Charlie Morton shut down Cincinnati's powerful lineup again, throwing a five-hitter for his second career shutout, and Pedro Alvarez hit a three-run homer Wednesday night, leading the Pittsburgh Pirates to a 5-0 victory that snapped their six-game losing streak.
Morton (5-1) avoided heavy rain for a change and stymied Cincinnati again. He threw a five-hitter for a 6-1 win at Great American Ball Park on April 15, coming within one out of his second career shutout.
Alvarez ended his streak of 15 games without driving in a run when he connected in the fourth off Bronson Arroyo (3-4), who has been prone to homers this season.
Andrew McCutchen added a two-run shot in the seventh. Arroyo has given up 10 homers, accounting for 16 of the 29 runs he's allowed.
