The Fantasy Baseball Sherpa

This is the fourth in a series of posts taking a look back at the top fantasy baseball performers for 2009. In this post I’ll review the top 10 Pitchers using a 5×5 NL-only format. For the purposes of this analysis I’m including Cliff Lee’s Phillies’ stats only (he ranked 47th based on 79.2 IP) and Jake Peavy’s Padres’ stats only (he ranked 59th based on 81.2 IP).

1. Tim Lincecum (Preseason rank was 3) - SF, SP

• Projected stats: 216 IP, 13 W, 0 SV, 3.63 ERA, 1.17 WHIP, 193 K, 2.76 Sherpa Pts

5. Adam Wainwright (10) - STL, SP

• Actual stats: 227 IP, 19 W, 0 SV, 2.58 ERA, 1.21 WHIP, 204 K, 2.98 Sherpa Pts
• Projected stats: 214 IP, 14 W, 0 SV, 3.53 ERA, 1.26 WHIP, 146 K, 2.36 Sherpa Pts

6. Josh Johnson (107) - FLA, SP

7. Matt Cain (22) - SF, SP

• Actual stats: 212.2 IP, 14 W, 0 SV, 2.88 ERA, 1.18 WHIP, 166 K, 2.58 Sherpa Pts
• Projected stats: 208 IP, 12 W, 0 SV, 3.94 ERA, 1.32 WHIP, 178 K, 1.52 Sherpa Pts

8. Jair Jurrjens (36) - ATL, SP

• Actual stats: 207 IP, 14 W, 0 SV, 2.61 ERA, 1.22 WHIP, 143 K, 2.50 Sherpa Pts
• Projected stats: 198 IP, 11 W, 0 SV, 4.59 ERA, 1.24 WHIP, 148 K, 1.35 Sherpa Pts

9. Wandy Rodriguez (69) - HOU, SP

• Actual stats: 199.2 IP, 14 W, 0 SV, 2.97 ERA, 1.23 WHIP, 190 K, 2.42 Sherpa Pts
• Projected stats: 151 IP, 9 W, 0 SV, 4.47 ERA, 1.37 WHIP, 133 K, 0.91 Sherpa Pts

10. Randy Wolf (105) - LAD, SP

• Actual stats: 209.1 IP, 11 W, 0 SV, 3.22 ERA, 1.08 WHIP, 158 K, 2.41 Sherpa Pts
• Projected stats: 157 IP, 9 W, 0 SV, 4.65 ERA, 1.46 WHIP, 135 K, 0.58 Sherpa Pts

Wandy Rodriguez and Randy Wolf were complete surprises to me - they both pitched ~50 innings more than I’d projected for them, but of course that’s primarily a result of the fact they pitched much better than I expected. Chris Carpenter is the classic boom-or-bust pitcher coming off an injury.  Before you run out and stock up on pitchers coming back from injuries in 2010, think of Ben Sheets, who represents the flip side of that coin.  In theory Strikeouts and WHIP should be easier to predict than ERA, Wins, and Saves (since the latter group are more a function of randomness and factors beyond a Pitcher’s direct control), but those predictions aren’t always the most accurate in practice. Dividing the Sherpa Pts by the IP gives a decent indicator of the overall accuracy of the initial projection compared to the actual results.

You’ll also note that only three of the Pitchers listed above were in my preseason top 10 list. Who were the other seven, and how did they fare? I’m glad you asked!

16. Johan Santana (1) - NYM, SP

• Actual stats: 166.2 IP, 13 W, 0 SV, 3.13 ERA, 1.21 WHIP, 146 K, 2.06 Sherpa Pts

59. Jake Peavy (2) - SD, SP

• Actual stats: 81.2 IP, 6 W, 0 SV, 3.97 ERA, 1.19 WHIP, 92 K, 0.88 Sherpa Pts
• Projected stats: 213 IP, 13 W, 0 SV, 3.17 ERA, 1.15 WHIP, 215 K, 3.26 Sherpa Pts

37. Cole Hamels (4) - PHI, SP

• Actual stats: 193.2 IP, 10 W, 0 SV, 4.32 ERA, 1.29 WHIP, 168 K, 1.31 Sherpa Pts
• Projected stats: 197 IP, 12 W, 0 SV, 3.56 ERA, 1.13 WHIP, 185 K, 2.97 Sherpa Pts

6. Roy Halladay (3) - TOR, SP

8. Adam Wainwright (13) - STL, SP
   • Actual stats: 227 IP, 19 W, 0 SV, 2.58 ERA, 1.21 WHIP, 204 K, 2.98 Sherpa Pts
   • Projected stats: 214 IP, 14 W, 0 SV, 3.53 ERA, 1.26 WHIP, 146 K, 2.36 Sherpa Pts
9. CC Sabathia (2) - NYY, SP
   • Actual stats: 227.1 IP, 19 W, 0 SV, 3.21 ERA, 1.10 WHIP, 194 K, 2.94 Sherpa Pts
   • Projected stats: 235 IP, 16 W, 0 SV, 3.14 ERA, 1.13 WHIP, 219 K, 3.68 Sherpa Pts
10. Justin Verlander (73) - DET, SP
    • Actual stats: 232.1 IP, 18 W, 0 SV, 3.45 ERA, 1.18 WHIP, 264 K, 2.86 Sherpa Pts
    • Projected stats: 198 IP, 12 W, 0 SV, 4.55 ERA, 1.33 WHIP, 160 K, 1.29 Sherpa Pts

As was the case last year, the most interesting observation from my perspective is the relative difficulty in projecting W, ERA and WHIP vs. projecting Ks. Injuries obviously impact the actual rankings (see Johan Santana, Jake Peavy, and Brandon Webb below), but so do incorrect initial estimates regarding Innings Pitched. Dividing the Sherpa Pts by the IP gives a decent indicator of the overall accuracy of the initial projection compared to the actual results.

You’ll also note that only four of the Pitchers listed above were in my preseason top 10 list. Who were the other six, and how did they fare? I’m glad you asked!

27. Johan Santana (1) - NYM, SP

• Actual stats: 166.2 IP, 13 W, 0 SV, 3.13 ERA, 1.21 WHIP, 146 K, 1.92 Sherpa Pts
• Projected stats: 225 IP, 14 W, 0 SV, 3.00 ERA, 1.09 WHIP, 218 K, 3.72 Sherpa Pts

63. Jake Peavy (5) - SD, SP

• Actual stats: 101.2 IP, 9 W, 0 SV, 3.45 ERA, 1.12 WHIP, 110 K, 1.36 Sherpa Pts
• Projected stats: 213 IP, 13 W, 0 SV, 3.17 ERA, 1.15 WHIP, 215 K, 3.20 Sherpa Pts

402. Brandon Webb (6) - ARI, SP

• Actual stats: 4 IP, 0 W, 0 SV, 13.50 ERA, 2.00 WHIP, 2 K, -0.10 Sherpa Pts
• Projected stats: 226 IP, 13 W, 0 SV, 3.38 ERA, 1.18 WHIP, 181 K, 2.89 Sherpa Pts

65. Cole Hamels (9) - PHI, SP

• Actual stats: 193.2 IP, 10 W, 0 SV, 4.32 ERA, 1.29 WHIP, 168 K, 1.36 Sherpa Pts
• Projected stats: 197 IP, 12 W, 0 SV, 3.56 ERA, 1.13 WHIP, 185 K, 2.71 Sherpa Pts

74. Rich Harden (9) - CHC, SP

• Actual stats: 141 IP, 9 W, 0 SV, 4.09 ERA, 1.34 WHIP, 171 K, 1.22 Sherpa Pts
• Projected stats: 143 IP, 10 W, 0 SV, 2.71 ERA, 1.11 WHIP, 161 K, 2.62 Sherpa Pts

69. Roy Oswalt (10) - HOU, SP

• Actual stats: 181.1 IP, 8 W, 0 SV, 4.12 ERA, 1.24 WHIP, 138 K, 1.27 Sherpa Pts
• Projected stats: 212 IP, 13 W, 0 SV, 3.48 ERA, 1.22 WHIP, 161 K, 2.53 Sherpa Pts

We’ll soon be starting work here in Sherpaville on our projections for the 2010 season, but I’ll continue this series with a look at the 2008 top 10 Hitters in an NL-only 5×5 format as time permits.

This time of year many fantasy baseball team owners look to trades in an effort to improve their place in the standings.  Of course, everyone’s ideal is to trade away players who will perform worse over the remainder of the season than they have year-to-date, while simultaneously trading for players who will perform better over the remainder of the season than they have year-to-date.

How should you assess a player’s year-to-date value vs. his forecasted remainder-of season value?  Using Fantasy Baseball Sherpa’s In-season Updates tool, an owner can quantify both of these values in an effort to identify players who are currently undervalued and overvalued.  Fantasy Baseball Sherpa assigns a score of 1.00 Sherpa Points to the league leader in each category.  All other players are assigned a score for that category based on their result relative to the league leader’s result.

For example, if the league leader has hit 26 HRs year-to-date, then a player who has hit 13 HRs year-to-date would be assigned a scoreof 0.50 Sherpa Points.  For ratio categories (e.g.- AVG, ERA) a proxy statistic is used.  A player’s scores in each category can be added up to determine the player’s Total Sherpa Points.  A player’s maximum score is equal to the number of categories used (note:  this maximum score will be different for Hitters and Pitchers if your league uses a different number of categories for Hitters and Pitchers).

Here are 10 National League Pitchers who are good buy-low candidates for a league using the standard 5 Pitching categories (Wins, Saves, Strikeouts, ERA, & WHIP) based on stats through games of Sun 6/21/09:

1. Rich Harden, SP, ChC (2.13 Remainder-of-Season Total Sherpa Points - 0.66 Year-to-Date Total Sherpa Points = +1.47)
2. Cole Hamels, SP, Phi (2.27 - 1.03 = +1.24)
3. Roy Oswalt, SP, Hou (1.93 - 0.78 =+1.15)
4. Johan Santana, SP, NYM (3.40 - 2.32 = +1.08)
5. Hiroki Kuroda, SP, LAD (1.48 - 0.46 = +1.02)
6. Jose Valverde, RP, Hou (1.52 - 0.56 = +0.96)
7. Ricky Nolasco, SP, Fla (0.52 - -0.26 = +0.78)
8. Carlos Zambrano, SP, ChC (1.99 - 1.24 = +0.75)
9. Tim Lincecum, SP, SF (3.27 - 2.56 = +0.71)
10. Ryan Dempster, SP, ChC (1.92 - 1.28 = +0.64)

Here are 10 National League Pitchers who are good sell-high candidates for a league using the standard 5 Pitching categories based on stats through games of Sun 6/21/09:

1. Zach Duke, SP, Pit (0.84 - 1.88 = -1.04)
2. Jason Marquis, SP, Col (0.75 - 1.55 = -0.80)
3. Jonathan Broxton, RP, LAD (1.91 - 2.61 = -0.70)
4. Livan Hernandez, SP, NYM (0.20 - 0.88 = -0.68)
5. Jeff Weaver, SP, LAD (0.01 - 0.60 = -0.59)
6. Johnny Cueto, SP, Cin (1.66 - 2.24 = -0.58)
7. Randy Wells, SP, ChC (0.43 - 1.00 = -0.57)
8. Chris Volstad, SP, Fla (0.51 - 1.02 = -0.51)
9. Brian Wilson, RP, SF (1.34 - 1.83 = -0.49)
10. Russ Ortiz, SP, Hou (0.06 - 0.55 = -0.49)

Of course, there are a number of reasons why a player’s performance over the remainder of the season may vary significantly from his performance year-to-date, including normal variation in results, injuries, changes in roles, etc.  By attempting to quantify both a player’s year-to-date and remainder-of-season results, we can take at least some of the guesswork out of identifying buy-low and sell-high candidates.

I’ll take a look at AL Hitters in my next post.

Until then,

This is the fourth in a series of posts taking a look back at the top fantasy baseball performers for 2008. Today I’ll review the top 10 Pitchers using a 5×5 NL-only format. For the purposes of this analysis I’m including CC Sabathia’s Brewers’ stats only.

7. Ricky Nolasco (N/A - didn’t even have him in my preseason database!) - FLA, SP

• Actual stats: 212.1 IP, 15 W, 0 SV, 3.52 ERA, 1.10 WHIP, 186 K, 2.60 Sherpa Pts
• Projected stats: N/A

8. CC Sabathia (1 in A.L.) - MIL, SP

• Actual stats: 130.2 IP, 11 W, 0 SV, 1.65 ERA, 1.00 WHIP, 128 K, 2.58 Sherpa Pts
• Projected stats: 227 IP, 15 W, 0 SV, 3.49 ERA, 1.17 WHIP, 196 K, 3.78 Sherpa Pts

9. Derek Lowe (16) - LAD, SP

10. Ben Sheets (28) - MIL, SP

• Projected stats: 137 IP, 8 W, 0 SV, 3.88 ERA, 1.16 WHIP, 121 K, 1.58 Sherpa Pts

Ricky Nolasco was obviously a complete surprise to me, and Ryan Dempster wasn’t far behind. In theory Strikeouts and WHIP should be easier to predict than ERA, Wins, and Saves (since the latter group are more a function of randomness and factors beyond a Pitcher’s direct control), but those predictions aren’t always the most accurate in practice. Dividing the Sherpa Pts by the IP gives a decent indicator of the overall accuracy of the initial projection compared to the actual results.

You’ll also note that only 4 of the Pitchers listed above were in my preseason top 10 list. Who were the other six, and how did they fare? I’m glad you asked!

We’re already busy here in Sherpaville developing projections for the 2009 season (we’re one of several projection providers selected for the 2009 season by Mock Draft Central!), but I’ll continue this series with a look at the 2008 top 10 Hitters in an AL-only 5×5 format as time permits.

Until next time,

This entry is the second in a series of posts taking a look back at the top fantasy baseball performers for 2008. Today I’ll continue with the top 10 Pitchers using a 5×5 mixed league format.

1. Roy Halladay (Preseason rank was 6) - TOR, SP
   • Actual stats: 246 IP, 20 W, 0 SV, 2.78 ERA, 1.05 WHIP, 206 K, 3.59 Sherpa Pts (out of a max of 5.00)
   • Projected stats: 208 IP, 13 W, 0 SV, 3.42 ERA, 1.14 WHIP, 134 K, 2.78 Sherpa Pts

3. Cliff Lee (298) - CLE, SP
   • Actual stats: 223.1 IP, 22 W, 0 SV, 2.54 ERA, 1.11 WHIP, 170 K, 3.33 Sherpa Pts
   • Projected stats: 50 IP, 3 W, 0 SV, 4.68 ERA, 1.36 WHIP, 33 K, 0.26 Sherpa Pts
4. Tim Lincecum (50) -SF, SP
   • Actual stats: 227 IP, 18 W, 0 SV, 2.62 ERA, 1.17 WHIP, 265 K, 3.32 Sherpa Pts
   • Projected stats: 183 IP, 9 W, 0 SV, 4.28 ERA, 1.20 WHIP, 203 K, 1.85 Sherpa Pts
5. Johan Santana (1) - NYM, SP

   • Projected stats: 224 IP, 15 W, 0 SV, 3.17 ERA, 1.03 WHIP, 237 K, 4.00 Sherpa Pts
6. Cole Hamels (21) - PHI, SP
   • Actual stats: 227.1 IP, 14 W, 0 SV, 3.09 ERA, 1.08 WHIP, 196 K, 2.88 Sherpa Pts
   • Projected stats: 187 IP, 12 W, 0 SV, 3.75 ERA, 1.16 WHIP, 188 K, 2.50 Sherpa Pts
7. Brandon Webb (3) - ARI, SP
   • Actual stats: 226.2 IP, 22 W, 0 SV, 3.30 ERA, 1.20 WHIP, 183 K, 2.74 Sherpa Pts
   • Projected stats: 231 IP, 14 W, 0 SV, 3.23 ERA, 1.19 WHIP, 182 K, 3.23 Sherpa Pts
8. Dan Haren (8) - ARI, SP
   • Actual stats: 216 IP, 16 W, 0 SV, 3.33 ERA, 1.13 WHIP, 206 K, 2.68 Sherpa Pts
   • Projected stats: 215 IP, 13 W, 0 SV, 3.64 ERA, 1.21 WHIP, 176 K, 2.62 Sherpa Pts
9. Ervin Santana (249) - LAA, SP
   • Actual stats: 219 IP, 16 W, 0 SV, 3.49 ERA, 1.12 WHIP, 214 K, 2.67 Sherpa Pts
   • Projected stats: 140 IP, 9 W, 0 SV, 5.21 ERA, 1.42 WHIP, 108 K, 0.42 Sherpa Pts
10. Ryan Dempster (198) - ChC, SP
    • Actual stats: 206.2 IP, 17 W, 0 SV, 2.96 ERA, 1.21 WHIP, 187 K, 2.56 Sherpa Pts
    • Projected stats: 80 IP, 6 W, 0 SV, 4.50 ERA, 1.40 WHIP, 70 K, 0.59 Sherpa Pts

The most interesting observation from my perspective - the relative difficulty in projecting W, ERA and WHIP vs. projecting Ks, and the number of Pitchers who seemingly came out of nowhere (i.e. - Lee, Ervin Santana, and Dempster). Injuries obviously impact the actual rankings (see John Smoltz and J.J. Putz below), but so do incorrect initial estimates regarding Innings Pitched. Dividing the Sherpa Pts by the IP gives a decent indicator of the overall accuracy of the initial projection compared to the actual results.

You’ll also note that only 5 of the Pitchers listed above were in my preseason top 10 list. Who were the other five, and how did they fare? I’m glad you asked!

21. Jake Peavy (2) - SD, SP

• Actual stats: 173.2 IP, 10 W, 0 SV, 2.85 ERA, 1.18 WHIP, 166 K, 2.11 Sherpa Pts
• Projected stats: 216 IP, 14 W, 0 SV, 3.17 ERA, 1.11 WHIP, 230 K, 3.62 Sherpa Pts

16. Roy Oswalt (5) - HOU, SP

• Actual stats: 208.2 IP, 17 W, 0 SV, 3.54 ERA, 1.18 WHIP, 165 K, 2.27 Sherpa Pts
• Projected stats: 224 IP, 14 W, 0 SV, 3.21 ERA, 1.25 WHIP, 166 K, 2.93 Sherpa Pts

188. John Smoltz (7) - ATL, SP

• Actual stats: 28 IP, 3 W, 0 SV, 2.57 ERA, 1.18 WHIP, 36 K, 0.47 Sherpa Pts
• Projected stats: 185 IP, 13 W, 0 SV, 3.41 ERA, 1.17 WHIP, 166 K, 2.70 Sherpa Pts

150. J.J. Putz (9) - SEA, RP

• Actual stats: 46.1 IP, 6 W, 15 SV, 3.89 ERA, 1.60 WHIP, 56 K, 0.63 Sherpa Pts
• Projected stats: 71 IP, 3 W, 33 SV, 2.41 ERA, 0.89 WHIP, 79 K, 2.32 Sherpa Pts

14. Mariano Rivera (10) - NYY, RP

• Actual stats: 70.2 IP, 6 W, 39 SV, 1.40 ERA, 0.67 WHIP, 77 K, 2.33 Sherpa Pts
• Projected stats: 74 IP, 3 W, 41 SV, 2.68 ERA, 1.03 WHIP, 70 K, 2.31 Sherpa Pts

We’re already busy here in Sherpaville developing projections for the 2009 season (we’re one of several projection providers selected for the 2009 season by Mock Draft Central!), but I’ll continue this series with a look at the 2008 top 10 Hitters in an NL-only 5×5 format as time permits.

Until next time,

The Sherpa

In my previous post I ranked the Top 10 Year-to-Date 5×5 Mixed League Hitters for the first quarter of the season. In this post I’ll do the same for Pitchers. The Sherpa Point system gives each Pitcher a score ranging from 0 to 1.00 in each of the 5 standard pitching categories (W, SV, K, ERA, WHIP). Essentially, the league leader in each category is given a score of 1.00, while all other Pitchers’ scores in that category are calculated as the ratio of their result to the league leader’s result.

For example, if Brandon Webb leads the league with 9 Wins, he gets a Sherpa Point score of 1.00 in the Wins category; a Pitcher with 6 Wins gets a score of 0.67; a Hitter with 3 Wins gets a score of 0.33, etc. A proxy statistic is used for average-based categories (e.g. - ERA, WHIP, K/BB, K/9).

The maximum Pitchers’ score is equal to the number of pitching categories. Statistics are taken from games through Tues 5/20/08.

Without further delay, here’s the list of the Top 10 Year-to-Date 5×5 Mixed League Pitchers:

1. Cliff Lee 3.34 (Preseason Projection was 0.26)
2. Brandon Webb 3.03 (3.23)
3. Cole Hamels 2.92 (2.50)
4. Edinson Volquez 2.77 (0.13)
5. Shaun Marcum 2.66 (0.93)
6. Tim Lincecum 2.59 (1.85)
7. Ervin Santana 2.50 (0.42)
8. Ryan Dempster 2.48 (0.59)
9. Carlos Zambrano 2.36 (2.34)
10. Daisuke Matsuzaka 2.34 (2.13)

Yes, it’s early, but even at this stage in the season it’s obvious that my Preseason Projections for Cliff Lee (50 IP, 3 Wins, 4.68 ERA, and 1.43 WHIP) were just a bit off. The Innings Pitched projection is obviously the driver - based on his performance the last 3 years, I didn’t believe he’d stick in the Indians’ rotation this year. Live and learn!

Webb and Hamels were in my Preseason Top 10, while Zambrano (13th), Matsuzaka (29th), and Lincecum (41st) all made my Preseason Top 50. However, the other 5 Pitchers on this list can all safely be termed “surprises”; I’ll venture a guess that if you have 2 or more of them on your roster (entirely possible), you’re probably sitting near the top of your league’s pitching standings.

Many notable names are missing from this list: Johan Santana (2.17 vs. Preseason Projection of 4.00); Jake Peavy (2.13 vs. 3.62); C.C. Sabathia (0.76 vs. 3.14); Roy Oswalt (0.61 vs 2.93); John Smoltz (1.41 vs. 2.70); Dan Haren (2.24 vs. 2.62); Aaron Harang (1.96 vs. 2.53); Erik Bedard (1.30 vs. 2.47). Just in case you’re curious, Jonathan Papelbon (1.89 vs 2.27), who ranks 24th Year-to-Date is the highest-ranked Closer; J.J. Putz (0.49 vs 2.32) was the highest-rated Closer (15th) in my Preseason Projections.

There is still plenty of time left for the Cliff Lees and the Ryan Dempsters to regress towards their expected values, and there’s plenty of time left for the C.C. Sabathias and Roy Oswalts to pitch the way most experts expected them to. I’ll be updating these rankings and comparisons for both Hitters and Pitchers periodically throughout the season.

Of course, lists like these are all well and good, but they don’t answer the obvious follow-up question: what should you expect these Hitters and Pitchers to do for the rest of the season?

I’ll begin to answer that question in a series of posts beginning early next week.

Until then,

The Sherpa

It happens every year, just like the swallows returning to San Juan Capistrano. A previously undistinguished hitter gets off to a fast start, and sportswriters speculate on whether a major league hitter will ever be able to hit .400 for an entire season again (I believe the answer is “no”, but that’s another topic for another day). If the same hitter were to hit .400 for 15 games in the middle of the season rather than at the beginning of the season, most of us would barely raise an eyebrow. However, due to what I referred to in a previous post as “Tuffy Rhodes Syndrome“, baseball fans tend to give a disproportionate amount of weight to events at the start of the season.

This year’s fast starters include A.J. Pierzynski (.421 as of this morning), Jason Kendall (.405), Angel Pagan (.385), Nate McLouth (.383), Luke Scott (.375), and Kurt Suzuki (.370). Obviously, none of these hitters will have a batting average anywhere near .400 when the season ends. But how many of them will finish with even a .300 average? Again, the answer could very well be zero.

So, how should you go about forecasting a batting average for the remainder of the season? Let’s use Pierzynski as an example. Suppose that going into the season you expected Pierzynski to hit .270 for the season. How should that expectation be combined with the .421 he’s hit through approximately the first 10% of the season? I’ve read a number of fantasy sportswriters’ articles on this subject, and their approaches usually fall into one of 2 categories: (1) expect Pierzynski to finish the season with his expected average of .270 (which implies that his average for the remaining 90% of the season will be .253); (2) expect Pierzynski to hit .270 for the rest of the season (which implies that his batting average for the season will be .285).

I disagree with both of these approaches. The first is an example of what statisticians refer to as the Gambler’s Fallacy, which means that (supposedly) independent events (such as future at-bats) are entirely dependent on past events. Andy Behrens, a very thought-provoking and entertaining fantasy sportswriter for Yahoo, had a great description of the Gambler’s Fallacy in a post he made yesterday. The second approach goes too far in the opposite direction, assuming that what a hitter has done season-to-date has zero predictive value in forecasting what he’s likely to do for the remainder of the season.

I suggest a third approach that combines what the hitter was expected to do with what the hitter has actually done in order to forecast what he’s likely to do for the remainder of the season. There are several possible weighting schemes, but for the sake of simplicity, I’ll go with a linear weighting scheme (i.e. - if the season is 10% complete, the hitter’s actual results should receive 10% weight, and his expected results should receive 90% weight). Applying this approach to the Pierzynski batting average example suggests that a reasonable forecast for Pierzysnki’s batting average for the rest of the season is .285 (which implies that his batting average for the season will be .299).

Some may still argue that .270 is a better forecast than .285. Let’s look at another example, this one from last season. If you expected Andruw Jones to hit .260 for the season, but he’s hitting just .211 at the All-Star break, would you still expect him to hit .260 for the remainder of the season? Probably not. Since the All-Star break occurs after roughly 55% of the season has been played, I would have forecast a rest-of-season average for Jones of .233 (= 55%*.211 + 45%*.260). Jones actually hit .236 for the rest of the season. I realize that one cherry-picked example doesn’t prove my argument, but hopefully, you get the idea.

How can you use this information to your advantage in your fantasy leagues? People often talk of wanting to “sell high and buy low” with respect to making early-season trades, but do you actually have the backbone required to do so? If so, congratulations - you’re probably well on your way to scooping up some above-average players at below-average prices. If not, re-read the above, pick some real-life examples from the current season, and follow them.

Others may have an easier time selling high on a fast-starting player than buying low on a slow-starting player. Who are some of this year’s “slow starters” who may be ideal buy-low candidates? C.C. Sabathia and Roy Oswalt come to mind immediately on the pitching side, while Carl Crawford, Alfonso Soriano, Robinson Cano, and Ryan Braun are among the hitters off to sub-par starts. A savvy team owner will rebuff your attempts to trade for one of these players, but some may be willing to part with these players for a below-market offer.

I’ll leave you with an example I witnessed last season. A friend had Alex Rodriguez on his team, but was struggling in the pitching categories. His league required that all trades be balanced from a position standpoint (i.e. - you couldn’t trade a Third Baseman straight up for a Pitcher). In late May/early June he took advantage of a fellow owner’s willingness to sell low on Garrett Atkins and buy high on the fast-starting Boof Bonser, trading A-Rod and Boof Bonser in exchange for Garrett Atkins and Johan Santana. As you might expect, my friend was able to climb a number of places in his league’s standings after pulling off that trade.

Until next time,

With just over a week gone in the 2008 baseball season the sky is officially falling. Those who drafted/bought C.C. Sabathia, Roy Oswalt, Jason Bay, J.J. Putz, Robinson Cano etc., are wondering why these players are off to lousy starts. Those who drafted/bought Johnny Cueto, Nate McLouth, Mark Reynolds, Livan Hernandez, Jason Kendall, Kerry Woods, etc., are congratulating themselves on their foresight. So, is your team doing as well as expected? If not, what should you do now?

Predictably, many fantasy baseball columnists are now churning out (or, more likely, recycling from last year) columns on how 10 games is too small a sample size to draw conclusions, how you shouldn’t make any panic moves, blah, blah, blah. The more adventurous (or less lazy) among them actually develop lists of players off to hot/cold starts and offer their expert opinions on which players will continue to over/underwhelm, and which ones will “regress to the mean”. Very little of this is helpful to you in your effort to manage your fantasy team, and unless you’re reading these pieces for entertainment purposes, you’re better off ignoring them.

Put it another way - if these same players had the same results over a 10 game stretch in July or August, would you notice? Assuming you did, would you be concerned enough to make a change to your roster? Probably not. Unfortunately, human nature being what it is, we generally give more weight to events that take place at the very beginning of the season (aka “Tuffy Rhodes Syndrome“) or at the very end of the season (aka “Tom Glavine Syndrome“).

So, is there any reason to consider making trades this early in the season? Some experts advise fantasy team owners to sit on their hands until at least the end of May before hitting the “Submit Trade” button unless your roster is decimated by an injury. I disagree. In addition to injuries, there are at least two other reasons to explore potential trades even this early in the season: (1) To shore up weak categories, and (2) To take advantage of another team owner’s desire to make quick and sweeping changes.

First, let me explain what I mean by shoring up weak categories. Do not judge which categories you’re weak in by the results of the first 10 days of the season. Rather, go back to the analysis you did on your team immediately following your draft/auction. Trust the instincts you had at that time over the reaction you currently have now that 10 games are in the books. Before a draft/auction I set a goal to assemble a team that can finish in the top third in every category. If I can achieve that kind of balance, there’s a good chance I’ll finish at the top of my league. Of course, trades, free agent acquisitions, and waiver claims are also necessary to maintain/improve your team during the course of the season, but without a good draft/auction, you’re digging yourself a deep hole that’s almost impossible to climb out of. Identify your post-draft/auction weaknesses and address them as soon as you are able.

Regarding the second reason to make trades at this point in the season, there’s at least one owner in every league who seems to panic and make an early-season trade that ultimately hurts their team more than it helps. Don’t let that be you! Case in point - last year I saw someone who panicked after Garrett Atkins got off to a slow start, then traded Atkins and Johan Santana for Alex Rodriguez and the overachieving Boof Bonser. Not surprisingly, the owner who received Atkins and Santana finished much higher in the standings at the end of the year.

Not every trade will be that one-sided, nor should it be. I obviously want my team to be better after a trade than it was before the trade; however, I don’t want the other owner to have buyer’s remorse to the point where they’d never want to trade with me again. Here are my recommendations in executing a trade, particularly early in the season:

1. Assess your roster’s strengths and weaknesses. The earlier you are in the season, the more weight you should be giving a player’s preseason projected performance vs. his actual season-to-date performance. Of course, you need to be mindful of injuries and role changes (e.g. - everyday players who lose their jobs, newly-minted Closers, etc.)
2. Assess your leaguemates’ rosters’ strengths and weaknesses. The obvious goal in doing so is to find several potential trading partners (not just one!) whose strengths match up well with your weaknesses, and vice versa.
3. Send out trade feelers without making formal proposals. Initiate contact with specific owners. One of my fantasy sports pet peeves is owners who update their “Trading Block” page with a list of the categories they’re weak in, followed by a list of the players they’re willing to trade in order to improve their team (usually their weakest players). Sorry, I’m not trading you A-Rod and Carlos Zambrano for Pedro Feliz and Jose Contreras. As with most other things in life, you’re much more likely to get what you want if you ask for it rather than wait for it to come to you.
4. Sort through the responses to your trade feelers, then make a specific proposal where it makes sense to do so. Most trade talks will die after the previous step. If you do identify an owner who seems interested in discussing matters further, throw out an initial proposal. This should not be your “best offer”, but it should be good enough that the other owner isn’t insulted and actually has to give your offer some serious thought. It’s fine to pursue this stage with multiple owners simultaneously, even if you’re offering the same player(s) to several of them.
5. Negotiate. Expect the other owner(s) to counter your initial proposal - that’s part of the game. Keep a sense of humor about this - after all, we’re talking about fantasy sports here, not a life and death matter!
6. Assess your options. After some finite period of time you’ll get a good sense of whether owners are willing to pull the trigger on a deal or not. Trust your instincts here too - if your potential trading partner is constantly hedging or stalling, you’re probably better off moving on. Compare the impact of a trade to the impact of adding a player through a free agent bid or waiver wire claim.
7. Decide. While it may seem like a waste of time to come this far, then decide not to complete a deal, it’s not. The adage “sometimes the best trades are the ones you don’t make” applies just as much in the fantasy sports world as it does in the professional sports world. At the very worst you’ll receive a more accurate read on how your fellow owners value your players, as well as how they value their own players. You may unknowingly be sowing the seeds for a future trade. If you decide to complete a deal, don’t look back! If the player you’ve just traded away hits three home runs in a game or pitches a complete game shutout, let it go. You’re making the trade for the rest of the season, not just for the next game or two.

Until next time,
