Over the past few days, Eno Sarris has been rolling out our consensus ranking for players at various positions. To create my rankings I used ZiPS rest of season stats to compile my rankings. The only time I changed my ranking was because of expected time lost on the D.L. For some players who are having a good 2012 season (Josh Reddick, Jed Lowrie, Allen Craig, Edwin Encarnacion and Trevor Plouffe), my rankings are lower than most people expected. Today, I am going to look at one cause for a player to be out performing his projections: injuries.
Note: I will be looking at lack of past playing time and a measurable change in talent for the other two causes for a player out performing there projections.
Injuries and how they relate to player performance are one of the few last few frontiers in sabermetric studies. This off season, in two separate studies, Mitchel Litchman (MGL) and myself looked at how injuries affect a hitter’s performance. In MGL’s study, he looked at players who went on the DL and how they performed. He found that hitters under performed their SLG in the year of the injury, but the rest of their traits stayed constant. In my study, I looked at players who played through injuries without going on the D.L. and found the same conclusion. In the year after the injury, the player exceeded their projected power numbers.
