CC Sabathia
Rupp began the 2015 season as the Phillies' backup catcher, but by the end of June, with primary catcher Carlos Ruiz struggling and Rupp's performance starting to improve, Rupp began to see increased playing time. On June 23, 2015, Rupp hit his first major league home run off New York Yankees pitcher CC Sabathia. He batted .217 in 2017.
