Major League pitcher performance after being placed on the disabled list

In Major League Baseball, pitchers, when injured, are placed on the disabled list (DL). We proposed that a decrease in performance occurs after being placed on the DL. We compared statistics of pitchers that were on the DL (study group) to pitchers that were not on the DL (control group) over a six year time period by analyzing three separate years (2007, 2010, and 2012 seasons). To determine the study and control group, the website prosportstransactions.com was used. For each variable, we set a minimum and maximum range and only pitchers whose statistics were within that range qualified. Fangraphs.com was used to determine pitching statistics: fastball velocity, strike to walk ratio (K/BB), walks plus hits per inning pitched (WHIP), earned run average (ERA (average amount of runs allowed by the pitcher)) and innings pitched per season (IP). Two hundred fifty pitchers were analyzed (125 in each group). In 2010, the control group (30) was significantly older (P=0.01) than the DL group (28.6). The ERA between both groups was significantly different, favoring the control group, during all three seasons. There were no significant differences when comparing fastball velocity, WHIP, and IP for any of the three seasons. We found that pitchers placed on the DL tended to have higher ERAs compared to pitchers that were not placed on the DL for the same season. The results of this study indicate that when pitchers are placed on the DL, their overall pitching performance decreases.
