[Arizona Sports] D-backs leave runners on, bullpen struggles in loss to Giants - Jake Diekman, acquired on trade deadline day on Tuesday, faced only three hitters in his D-backs debut, committed an error, walked two, tossed a wild pitch and was charged with an unearned run. Brad Ziegler then made his (second) D-backs debut, pitching parts of the seventh and eighth innings and allowing four runs on three hits, a walk and a strikeout. But an oddity occurred in the eighth inning. With Ziegler on the mound, Lovullo made a mound visit, during which time the Giants called upon Alen Hanson to pinch hit.
