Arrieta's slow delivery didn't help catcher Miguel Montero, who is now 0-for-31 in throwing out baserunners for the season.
"It really sucked because the stolen base goes on me," Montero said. "When you really look at it, the pitcher doesn't give me any time. It's like, 'Oh, yeah, Miggy can't throw anybody out.' Yeah, but my pitchers don't hold anybody on. It's tough. ... I don't get a chance to throw.
