SAN FRANCISCO — Henry Davis’ fielder’s-choice grounder brought home the go-ahead run in the 10th inning, and the Pittsburgh Pirates completed a three-game sweep of the San Francisco Giants with a 2-1 victory on Wednesday.

Pittsburgh has won five in a row. San Francisco went 0-6 on its homestand, the first time since 1896 the Giants franchise has gone winless on a homestand of six or more games, according to the Elias Sports Bureau. The Giants also dropped below .500 (54-55) for the first time this season.

San Francisco was swept last weekend by the New York Mets.

With runners at the corners in the 10th, Davis hit a comebacker to Ryan Walker (2-4). Instead of throwing to the plate to get Oneil Cruz, Walker went to second to try to get a double play. Jack Suwinski was running on the pitch and beat the throw. Davis was retired.

Isaac Mattson (3-1) worked two scoreless innings. He struck out Patrick Bailey and Heliot Ramos with runners at second and third for the final two outs.

Pittsburgh starter Mike Burrows allowed one run on three hits in six innings. He struck out seven and walked one. The Giants’ Logan Webb gave up one run on five hits in 5 2/3 innings. He struck out 11 and walked four.

Up next, Pittsburgh’s Andrew Heaney (5-9, 4.79 ERA) faces host Colorado’s Antonio Senzatela (4-4, 6.68) on Friday. San Francisco takes on the host New York Mets and David Peterson (7-4, 2.83) on Friday.

PIRATES 3, GIANTS 1

SAN FRANCISCO (AP) — Liover Peguero homered for the first time in nearly two years, Joey Bart singled in the go-ahead run against his former team and Pittsburgh won their fourth straight game by beating skidding San Francisco.

San Francisco has lost five in a row and 11 of 13 overall.

Peguero’s solo shot in the fifth inning was the first in the majors for the Pirates shortstop since Sept. 9, 2023, and it marked a rare mistake on this night by 42-year-old Justin Verlander.

Coming off his first win in a Giants uniform, the three-time Cy Young Award winner had seven strikeouts and allowed six hits in five innings. He remains 37 wins shy of 300 for his career.

Peguero also drove in a run on a grounder in the eighth off Tyler Rogers (4-3) after Bart’s single gave the Pirates a 2-1 lead. Bart spent his first four seasons with the Giants.

Pittsburgh reliever Braxton Ashcraft (3-1) pitched three scoreless innings. Dennis Santana retired three batters for his sixth save.
