Trevor Williams outdueled Jacob deGrom, helping the Pittsburgh Pirates to a 5-0 win over the Mets on Saturday.
Williams (9-7) allowed five hits in six innings with five strikeouts and three walks. He hasn’t allowed a run in 17 straight innings since he surrendered three in the third inning of a 17-5 loss to the Philadelphia Phillies.
The Pirates have won 13 of their past 15 games, while the Mets have lost two straight after winning their previous three games.
Pittsburgh’s first run came after deGrom (5-6) began the sixth inning with two strikeouts. Gregory Polanco singled down the right-field line before stealing second. Colin Moran singled to right, scoring Polanco.
David Freese, who had five runs batted in during a 5-4 win Friday, pinch-hit in the seventh, grounding out but scoring Jordan Luplow from third. Adam Frazier followed with a double to right, driving in Jordy Mercer from second to make the score 3-0.
Moran drove in Polanco again with a single up the middle in the eighth, extending the Pirates’ lead to 4-0. Polanco was 3 for 4 with two doubles; Moran was 2 for 4 with two R.B.I.
Francisco Cervelli made it 5-0 later in the eighth with a single that scored Luplow.
Williams got out of trouble in consecutive innings, first when he got Devin Mesoraco to ground into a double play with one out and the bases loaded in the fourth. An inning later, he struck out Brandon Nimmo and forced Wilmer Flores to pop up to third, stranding runners on first and second.
DeGrom lost for the fourth time since June 28, when he last won a start. He allowed three runs on eight hits, his most surrendered this season, with five strikeouts in seven innings.
Luis Guillorme was recalled from Class AAA Las Vegas to replace Asdrubal Cabrera, who was traded Friday to the Phillies. Guillorme, a 23-year-old rookie, had a .172 batting average with four R.B.I. in 29 games with the Mets earlier this season. … The right-handed pitcher Zack Wheeler (4-6, 4.33 E.R.A.), the subject of recent trade rumors, will have the chance to carry momentum from his past two starts into Sunday against the Pirates. He won each while allowing a combined six runs on 12 hits in 14⅔ innings pitched.
