The Fantasy Baseball Sherpa

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

10. Ben Sheets (28) - MIL, SP

• Actual stats: 198.1 IP, 13 W, 0 SV, 3.09 ERA, 1.15 WHIP, 158 K, 2.41 Sherpa Pts
• 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!

12. Jake Peavy (2) - SD, SP

• Projected stats: 216 IP, 14 W, 0 SV, 3.17 ERA, 1.11 WHIP, 230 K, 3.62 Sherpa Pts

11. Roy Oswalt (4) - HOU, SP

• Actual stats: 208.2 IP, 17 W, 0 SV, 3.54 ERA, 1.18 WHIP, 165 K, 2.33 Sherpa Pts
• Projected stats: 224 IP, 14 W, 0 SV, 3.21 ERA, 1.25 WHIP, 166 K, 2.93 Sherpa Pts

99. John Smoltz (5) - ATL, SP

• Actual stats: 28 IP, 3 W, 0 SV, 2.57 ERA, 1.18 WHIP, 36 K, 0.48 Sherpa Pts
• Projected stats: 185 IP, 13 W, 0 SV, 3.41 ERA, 1.17 WHIP, 166 K, 2.68 Sherpa Pts

98. Aaron Harang (8) - HOU, SP

• Actual stats: 184.1 IP, 6 W, 0 SV, 4.78 ERA, 1.38 WHIP, 153 K, 0.52 Sherpa Pts

60. Chris Young (9) - SD, SP

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 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
