The Impact of Tommy John Surgery on Free Agent Pitcher Contracts in Major League Baseball

Abstract

This research examines whether Tommy John surgery has an effect on the Major League Baseball’s starting pitchers’ free agent contracts. I have used historical data on player performance and salary to see if there are differences in pay levels and the efficiency of the contract between pitchers who have had Tommy John surgery and those who have not. I have found that Tommy John surgery does not have a significant impact determining their contract, but prior performance is the main determination factor for their contracts. Furthermore, I found that salary efficiency depends on the players’ prior performances and not Tommy John surgery.
