Patrick Corbin held the Cubs to one run on four hits over six innings Tuesday for his 12th win of the season. He fanned six and walked three. Corbin (12-1, 2.31 ERA) has allowed exactly one run apiece in his last three starts, winning each. The young left-hander sits at 136 1/3 innings after throwing a career-high 186 1/3 frames between the majors and minors last season. Arizona hasn't announced a pitch cap, but keep an eye on the southpaw's workload as the summer escalates.
