Description
Ulnar collateral ligament reconstructive surgery, commonly referred to as Tommy John surgery, is a procedure that many Major League Baseball pitchers undergo. This research explores the effect of Tommy John surgery on MLB pitching performance, measured by average fastball velocity, home runs, strikeouts, and walks, using a time series cross-sectional model. Results indicated that at the 5% level of significance, Tommy John surgery has a positive impact on average fastball velocity and strikeouts per inning pitched controlling for age, seasons missed, and rehab innings pitched. The results of this research are contrary to those of other studies. It is hoped that this research will spark conversation on the impact of Tommy John surgery.
