Wainwright (16-9) had given up 15 earned runs over his previous two starts, both against Cincinnati. He allowed a career-high nine runs in two innings of a 10-0 loss Aug. 28. But he regained his form against the Pirates allowing just two hits.
Jeff Locke (9-5) allowed three runs on three hits over five innings.
Red Sox 13, Yankees 9
Mike Napoli hit two home runs, Jonny Gomes and prized rookie Xander Bogaerts also connected, and the Boston Red Sox kept up their dizzying scoring spree at Yankee Stadium, bashing New York 13-9 Saturday for their fifth straight win.
The AL East leaders became the first visiting team in more than a century to score at least nine runs on three straight days against the Yankees. In fact, the last time it happened, they weren’t called the Yankees — Boston did it in 1912 to the Highlanders at Hilltop Park.
Down 12-3, the Yankees rallied with four runs in the sixth inning and chased John Lackey (9-12). Mark Reynolds added a two-run double in the eighth off Red Sox reliever Drake Britton that made it 12-9.
David Ortiz and Dustin Pedroia each contributed to Boston’s five doubles. By the end of the fourth inning, it was 10-2 and every Red Sox batter had gotten a hit.
The Yankees scored at least six runs for the sixth game in a row. That wasn’t enough for David Huff (2-1), tagged for nine runs and eight hits in 3 1-3 innings.
ROYALS 4, TIGERS 3
Salvador Perez hit a two-run homer off Justin Verlander and the Kansas City Royals beat the Detroit Tigers 4-3 on Saturday night.
Perez drove a two-out pitch over the left-field wall to put the Royals ahead 4-2.
Verlander (12-11) is 0-3 with three no-decisions in six starts since an Aug. 6 victory at Cleveland.
The Tigers have dropped his past six starts and are 13-17 in his 30 starts this season.
