PITTSBURGH — Bryan Reynolds’ two-run bloop single capped a three-run ninth inning as the Pittsburgh Pirates rallied for a 6-5 victory over the Miami Marlins on Wednesday night.

Elias Diaz started the winning rally with a leadoff homer against Jose Urena (4-8) that drew the Pirates within a run. Pinch-hitter Kevin Kramer then walked and went to third on Adam Frazier’s double before Reynolds flared a single into left-center to give the Pirates their fifth win in six games.

Frazier and Reynolds both had two hits at the top of the order.

Garrett Cooper’s two-run homer off Kyle Crick with two outs in the seventh put the Marlins ahead 5-3.

Miami’s Starlin Castro had four hits, all for extra bases, as he homered and doubled three times. Cooper also had a double among his three hits.

Wei-Chung Wang (2-1) pitched a scoreless ninth.

Marlins rookie Robert Dugger was in line for his first major league win after allowing three runs — two earned — over six innings in his third career start.

Pirates starter Trevor Williams basically matched Dugger’s line as he gave up three runs — two earned — and seven hits in six innings, though he had six strikeouts and one walk.

Castro’s two-run homer in the fifth put Miami ahead 3-1. Pittsburgh tied it on Frazier’s run-scoring triple in the fifth and pinch-hitter Pablo Reyes’ RBI double in the sixth.

Josh Bell drove in the Pirates’ first run with a first-inning single.
