The Fantasy Baseball Sherpa

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 Hitters who are good buy-low candidates for a league using the standard 5 Hitting categories (AVG, Home Runs, RBI, Stolen Bases, & Runs Scored) based on stats through games of Sun 6/21/09:

1. Alfonso Soriano, OF, ChC (2.79 Remainder-of-Season Total Sherpa Points - 1.50 Year-to-Date Total Sherpa Points = +1.29)
2. Carlos Gonzalez, OF, Col (1.33 - 0.20 = +1.13)
3. Jimmy Rollins, SS, Phi (2.18 - 1.06 =+1.12)
4. Geovany Soto, C, ChC (1.55 - 0.50 = +1.05)
5. Chris Coghlan, 3B/OF, Fla (1.81 - 0.77 = +1.04)
6. Lance Berkman, 1B, Hou (2.53 - 1.55 = +0.98)
7. Andrew McCutchen, OF, Pit (1.68 - 0.72 = +0.96)
8. Ryan Ludwick, OF, StL (2.17 - 1.22 = +0.95)
9. Brian Giles, OF, SD (1.04 - 0.10 = +0.94)
10. Everth Cabrera, SS, SD (1.05 - 0.15 = +0.90)

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

1. Orlando Hudson, 2B, LAD (1.41 - 2.18 = -0.77)
2. Raul Ibanez, OF, Phi (2.49 - 3.21 = -0.72)
3. Justin Upton, OF, Ari (2.00 - 2.65 = -0.65)
4. Todd Helton, 1B, Col (1.80 - 2.26 = -0.46)
5. Clint Barmes, 2B/SS, Col (1.50 - 1.90 = -0.40)
6. Pablo Sandoval, C/1B/3B, SF (1.67 - 2.03 = -0.36)
7. Gary Sheffield, OF, NYM (1.14 - 1.40 = -26)
8. Mark Reynolds, 1B/3B, Ari (2.38 - 2.62 = -0.24)
9. Nick Johnson, 1B, Was (1.59 - 1.82 = -0.23)
10. Michael Bourn, OF, Hou (1.86 - 2.08 = -0.22)

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.

• Actual stats: 611 AB, 37 HR, 106 RBI, 14 SB, .285 AVG, 92 R, 2.73 Sherpa Pts
• Projected stats: 592 AB, 39 HR, 99 RBI, 19 SB, .280 AVG, 104 R, 2.86 Sherpa Pts

The most interesting observation from my perspective - the impact of batting order position (imagine what Hanley Ramirez could do if he batted 3rd or 4th) and the lower-than-expected SB totals for both Ramirez and Jose Reyes, which bring them back to the pack somewhat in the overall rankings. Injuries also impacted the actual rankings (e.g. - Matt Holliday and Chase Utley), as did the lack of anticipated injuries (e.g. - Albert Pujols). Ryan Ludwick is the only name on the list I’d term a complete surprise. Dividing the Sherpa Pts by the AB gives a decent indicator of the overall accuracy of the initial projection compared to the actual results.

You’ll also note that only 6 of the Hitters listed above were in my preseason top 10 list. Who were the other four, and how did they fare? I’m glad you asked!

11. Ryan Howard (6) - PHI, 1B

• Actual stats: 610 AB, 48 HR, 146 RBI, 1 SB, .251 AVG, 105 R, 2.71 Sherpa Pts
• Projected stats: 560 AB, 44 HR, 130 RBI, 2 SB, .313 AVG, 116 R, 3.44 Sherpa Pts

29. Jimmy Rollins (7) - PHI, SS

• Actual stats: 556 AB, 11 HR, 59 RBI, 47 SB, .277 AVG, 76 R, 2.10 Sherpa Pts
• Projected stats: 684 AB, 24 HR, 81 RBI, 39 SB, .289 AVG, 128 R, 3.12 Sherpa Pts

25. Alfonso Soriano (9) - ChC, OF

• Actual stats: 453 AB, 29 HR, 75 RBI, 19 SB, .280 AVG, 76 R, 2.17 Sherpa Pts
• Projected stats: 645 AB, 39 HR, 85 RBI, 26 SB, .285 AVG, 110 R, 3.02 Sherpa Pts

21. Derrek Lee (10) - ChC, 1B

• Actual stats: 623 AB, 20 HR, 90 RBI, 8 SB, .291 AVG, 93 R, 2.26 Sherpa Pts
• Projected stats: 575 AB, 28 HR, 92 RBI, 14 SB, .311 AVG, 100 R, 2.95 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 Pitchers in an NL-only 5×5 format as time permits.

Until next time,

The Sherpa

With just over 25% of the 2008 season already in the books many experts are now putting forth their “Biggest Surprises” and “Biggest Disappointments” lists. I will do something similar in this post, but I will also give you the actual impact these players have had year-to-date in a league that uses the standard 5×5 scoring categories.

Let’s look at Hitters first. The Sherpa Point system gives each Hitter a score ranging from 0 to 1.00 in each of the 5 standard hitting categories (AVG, HR, RBI, SB, R). Essentially, the league leader in each category is given a score of 1.00, while all other Hitters’ scores in that category are calculated as the ratio of their result to the league leader’s result.

For example, if Lance Berkman leads the league with 16 HRs, he gets a Sherpa Point score of 1.00 in the HR category; a Hitter with 8 HRs gets a score of 0.50; a Hitter with 4 HRs gets a score of 0.25, etc. A proxy statistic is used for average-based categories (e.g. - AVG, OBP, SLG, OPS)

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

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

1. Lance Berkman 4.13 (Preseason Projection was 2.80)
2. Chipper Jones 3.03 (2.58)
3. Dan Uggla 2.72 (1.89)
4. Josh Hamilton 2.70 (1.74)
5. Nate McLouth 2.69 (1.82)
6. Chase Utley 2.66 (3.22)
7. Hanley Ramirez 2.64 (3.41)
8. Albert Pujols 2.61 (3.32)
9. Carlos Quentin 2.55 (1.92)
10. Miguel Tejada 2.51 (2.38)

Berkman is obviously outperforming his projections by the largest amount so far (and will likely come back down to earth in short order), but Dan Uggla, Josh Hamilton, and Nate McLouth have probably offered the greatest value so far relative to where they were picked in drafts and the amount paid for them in auctions. Of the Top 10 shown here, only three (Utley, Ramirez, and Pujols) were among the Preseason Top 10 Hitters.

Many others who went in the first round of many drafts have not fared well in the early stages of the season. Consensus top-pick Alex Rodriguez (1.01 Year-to-Date vs. 3.84 Preseason Projection) and reigning NL MVP Jimmy Rollins (1.22 vs. 3.05) have missed significant time due to injuries. Other highly touted players who have disappointed their owners so far: Jose Reyes (1.73 vs. 2.98), David Wright (2.11 vs. 3.40), Ryan Braun (2.29 vs. 2.82), Miguel Cabrera (1.51 vs. 3.40), David Ortiz (1.88 vs. 3.44), Matt Holliday (2.17 vs. 3.56), Carl Crawford (2.18 vs. 3.19), Vladimir Guerrero (1.17 vs. 3.08), and Ryan Howard (1.08 vs. 3.07).

The discrepancy between a player’s Year-to-Date Sherpa Point score vs. his Preseason Projected Sherpa Point score can also be used as an indicator for constructing trade proposals. If you have a player on your team who is outperforming his projection by half a point or more, and you have several glaring weaknesses elsewhere on your roster, I would definitely be looking to sell high on that player. Conversely, if some of these players have disappointed other owners in your league, it may be worth inquiring about the possibility of buying low. If you can flip an overperforming player for an underperforming one, you have mastered the art of trading!

I’ll put together a similar list for Pitchers in my next post.

Until then,

So, you’re in a 12-team 5×5 Mixed league snake draft, you pick towards the end of the first round, and Albert Pujols is still available. Do you bite?

I say no, unless you have the 12th pick and can immediately make your second selection. The adage about “high risk, high reward” doesn’t apply to fantasy baseball drafts - you must, must, must get a “sure thing” with your first-round pick. That means identifying players with known injuries in Spring Training and avoiding them like the plague in the first round. Before the news of the extent of Pujols’ injuries came out, I based my projections for him on the assumption that he would play 155 games this season. At that point I would have considered him with the 9th pick, factoring in the Position Scarcity analysis that underlies my player rankings. After the news came out, I scaled back my assumption to 145 games, and even that may be too optimistic. If Pujols’ health concerns persist and the Cardinals are as bad as I think they’ll be this year (i.e. - they’re mathematically eliminated in late August/early September), I think it’s definitely possible that the Cardinals and Pujols would mutually agree that it’s in their best long-term interests to cut short his season (ala Dwyane Wade).

So, why would I argue that Pujols is a good pick with the last pick in the first round or the first pick in the second round, but not a few picks before that? At that point I think the risk vs. reward scale tips back in favor of the reward, so I’d be willing to take that chance. I wouldn’t pair Pujols with Johan Santana - you need to get at least one “sure thing” Hitter in the first two rounds. However, if I could pair Pujols with a first-round pick of Miguel Cabrera, Ryan Braun, Chase Utley, Jose Reyes, or Jimmy Rollins, then I would consider the reward to outweigh the risk. But even if I did that, I wouldn’t necessarily commit to keeping Pujols for the whole season. Suppose Pujols gets off to a strong start, and the concerns about his injury subside temporarily. In that case I would look to package him with someone else on my team who’s off to an unsustainable start in return for two above-average players who help me in my weaker categories.
