not solely but he ain't helping. if he and his pitcher ain't limiting the runs to just 2 or 3, then he's not doing his job. whatever he does for his bats is just extras.
I love Dusty as a person and I wish him nothing but the best, but not pinch hitting for Maldonado with a leadoff man on 2nd base and down by 5 is inexcusable. That's just unacceptable game management.
Offensively, he has to end more innings and strand more runners than any one else...has to. He may not be our worst problem but he's in the top 2.
