PECOTAs Crystal Ball-American League

My favorite web site is baseballprospectus.com. The writers on this site do a better job than anyone I know analyzing baseball. But the site is not for everyone. If you are literate in the language of BABIP, FIP, VORP and their signature projection system called PECOTA you'd probably enjoy it more. PECOTA stands for player empirical comparsion and optimization test algorithm. Quite a mouthful huh. I really can't fully explain how it works, but it DOES. Of course its not 100%. But year after year its by far the most accurate predictive system. The prediction that seemed to get the main streams attention was 2 seasons ago after finishing with only 66 wins PECOTA tabbed the Rays to finish with 90 wins and make the playoffs. While most of us in Florida knew the Rays were improving, 90 wins seemed like a pike dream. The rational was the Rays went from the worst defensive team to one that should be very much improved by getting Jason Bartlett, moving BJ Upton to center, moving Iwamura to second. And they for saw Longo taking over third very early in the season. They predicted this unit would become an over average fielding unit. Which in turn would help the young pitchers. And they hit it right on the nose. This is just one of many things I could point to. So this week when BP released its early PECOTA forecasts I thought it would be interesting to post the predictions and get your feedback. The first thing the suprised me about the AL predictions was no shockers. PECOTA usually hits one underdog. The three best teams are in one division. The biggest surprise alot will find is the outcome of the shortstack. So without further ado here are the predicted standings as of Feb.1 and the top 10 in each of the 5 fantasy categories. I'll do the NL next. And when they have their final predictions right before the season I'll post those.

So what do you guys think? Please comment on what you think PECOTA got right and what they got wrong.

  1. Quick glance - they got Seattle wrong as I have Seattle battling it out with Texas for the top spot with the Angels close behind. They also have made too great an emphasis on Texas' HR power and with Kinsler projected to hit 5th, he doesn't lead the league in runs scored as that will be down to around 85-90.
