That's kinda the point. In a league that uses OBP, R, RBI, SB, TB Trout is outproducing Segura comfortably in every category except SB. Defense doesn't mean crap.
Also, you're a big stat buff, so tell me how Segura's going to keep up having a decent OBP with a .353 BABIP and a walk rate below 4%? Or are stats only applicable for players you're not high on?
