PITTSBURGH — Bryce Harper’s go-ahead RBI single was one of 15 hits the Philadelphia Phillies used to beat the Pittsburgh Pirates 6-1 on Friday night, giving them back-to-back victories for the first time since July 2.

Harper hit a seventh-inning single off Pirates reliever Richard Rodríguez (3-4) that scored pinch-hitter Brad Miller to give the Phillies their first lead of the game.

Rookie outfielder Adam Haseley added a solo homer to start the scoring and a run-scoring double to cap it for the Phillies.

Miller reached on a single to left and advanced on a walk and fielder’s choice to set the table for Harper, who finished 2 for 5 with a double. The run snapped a 19-game scoreless streak for Rodríguez.

Philadelphia made it 3-1 in the eighth inning on Jean Segura’s bases-loaded infield single that followed a 13-pitch battle with reliever Kyle Crick.

In the ninth, Maikel Franco drove in J.T. Realmuto with another infield single, César Hernández scored on a wild pitch and Haseley plated Franco with a double.

Haseley also hit a solo homer in the fifth inning, his second in two games.

The rally made a winner of Juan Nicasio (2-3), who pitched one-third of an inning in relief of starter Jake Arrieta. Arrieta worked 5 2/3 innings of one-run ball. He struck out four and allowed six hits.

Cole Irvin pitched two innings for his first save.

Pirates starter Jordan Lyles bounced back from his worst start of the season, striking out seven in 5 2/3 innings while allowing one run. In his previous start, he gave up seven runs and didn’t get out of the first inning.
