The Diamondbacks plan to use Brad Ziegler in the closer role for the time being. It seemed evident that Ziegler was the favorite for saves in Arizona after he nailed down his third save in as many appearances on Monday. The side-armer boasts a 2.58 ERA and 1.06 WHIP in 51 appearances this season, though he's struck out just 24 over 45 1/3 frames. Ziegler has been vulnerable to left-handed bats in his career but has managed to hold them in check this season.
