The rest of the team has had RISP on 24.25 percent of its at bats. Mauer has had RISP in 20.10. Also, I don't know how to easily figure out who was on base for Mauer, but with where he has been in the batting order, the vast majority of his games have come with guys like Garver, Wilson, Grossman, Lomo, and even the pitcher batting up to three batters in front of him. Specifically, in his 63 games as a lead off hitter, 47 times the No. 9 hitter has been Wilson (27), Garver (7), Adrianza (7), or a pitcher (6). When your guy on 2B is Wilson, you're not going to get as many RBIs as when your guy is Rosario. Also, take into account that Mauer doesn't hit homers. The batter, by definition, isn't in scoring position. Mauer has driven in 34 base runners. For context, in more at bats for each, Dozier drove in only 36 and Kepler 29 base runners. All factors in why a guy with great success with RISP may not have gobs of RBIs.
