Brandon Pfaadt shut out the Pirates for seven innings Tuesday before being left with a no-decision.
Pfaadt departed with a six-run lead, only to watch Ryan Thompson give up three runs in the eighth and Paul Sewald surrender two homers to tie the game in the ninth. Before that, Pfaadt allowed six hits, walked one and struck out four. He had won five straight starts since rejoining Arizona’s rotation on June 30, but the best performance of the bunch wasn’t enough to make it six straight. He’ll likely make his next start Monday against the Padres.
