Using data from the 2000-2016 Major League Baseball seasons, this paper looks at the determinants of durability amongst baseball athletes, durability is measured in games played for batters and innings pitched for pitchers, with a particular focus on height and weight. This paper finds evidence that lighter, shorter batters play significantly more games than taller, heavier batters. Additionally, amongst pitchers, there is only circumstantial evidence that height and weight are important determining factors of player durability. Finally, I find that starting pitchers increase the likelihood of becoming injured in the regular season by 10.3% and 21.8% if their hits per nine innings and home runs per nine inning totals, respectively increase by one.
