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

• Actual stats: 225.1 IP, 15 W, 0 SV, 2.48 ERA, 1.05 WHIP, 261 K, 3.46 Sherpa Pts (out of a max of 5.00)
• Projected stats: 220 IP, 12 W, 0 SV, 3.23 ERA, 1.19 WHIP, 259 K, 3.20 Sherpa Pts

• Projected stats: 175 IP, 11 W, 0 SV, 3.61 ERA, 1.33 WHIP, 152 K, 1.78 Sherpa Pts

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

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

We’re getting ready here in Sherpaville to develope our projections for the 2010 season, 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,

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.

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,

The Sherpa

In this post I’ll take a look at the Top 10 Pitchers (both year-to-date and for the rest of the season) in a standard mixed league format (i.e. - Pitching categories are Wins, Saves, Strikeouts, ERA, and WHIP). Each player receives a Sherpa Point score ranging from 0 to 1 in each of the 5 categories; thus, the maximum possible score is 5.00.

For the counting statistics the league leader is assigned a score of 1.00; all other Pitchers’ scores are calculated by taking the ratio of their score in a particular category to the league leader’s score. For example, if the league leader has 15 Wins, a Pitcher with 10 Wins would receive a score of .67, a Pitcher with 5 Wins would receive a score of .33, etc. For average-based categories (e.g. - ERA and WHIP) a proxy statistic is used. Pitchers’ Sherpa Points scores in each individual category are added to calculate the Total Sherpa Points.

Top 10 Pitchers Year-to-Date

1. Cliff Lee - 3.60 (Remainder-of-Season forecast = 2.48 Sherpa Points, which ranks 18th overall)
2. Roy Halladay - 3.45 (3.68, 2nd)
3. Dan Haren - 3.39 (3.59, 3rd)
4. CC Sabathia - 3.22 (3.69, 1st)
5. Brandon Webb - 2.94 (3.25, 5th)
6. Justin Duchscherer - 2.93 (2.61, 13th)
7. Cole Hamels - 2.93 (2.96, 8th)
8. Tim Lincecum - 2.84 (2.44, 19th)
9. Ben Sheets - 2.67 (2.52, 17th)
10. Ervin Santana - 2.66 (2.03, 36th)

Top 10 Pitchers for Remainder of Season

1. CC Sabathia - 3.69 (Year-to-Date score = 3.22 Sherpa Points, which ranks 4th)
2. Roy Halladay - 3.68 (3.45, 2nd)
3. Dan Haren - 3.59 (3.39, 3rd)
4. Johan Santana - 3.35 (2.32, 16th)
5. Brandon Webb - 3.25 (2.94, 5th)
6. Jake Peavy - 3.25 (2.16, 22nd)
7. John Lackey - 3.13 (1.88, 34th)
8. Cole Hamels - 2.96 (2.93, 7th)
9. Mariano Rivera - 2.83 (2.33, 15th)
10. James Shields - 2.69 (2.27, Tied for 17th)

As you would expect, there’s more of a difference between the Year-to-Date and Remainder-of-Season results for Pitchers than there is for Hitters. While hitting stats are somewhat team dependent (e.g. - RBI, Runs Scored), a Pitcher’s Wins are much more team dependent, which makes them more difficult to predict accurately.

In my next post I’ll take a look at the Top 10 Hitters in an AL-only format.

Until then,
