His story can be told with two numbers: 6 and 8. He walked only six batters in 33 innings of work, but he gave up eight home runs. This suggests a pitcher who is throwing it in there and hoping that they don’t hit it too far. He doesn’t strike out many batters, didn’t have good minor league stats before 2015, and got absolutely clobbered in his one post-season appearance, so there’s no reason to hope for much.
Fun stat: in 2013, when pitching in class AA ball, Tepera hit 12 batters in 116 innings. Ouch! (The major league leader in plonkings this season was 13, shared by four pitchers.)
