PITTSBURGH — Anthony DeSclafani allowed one hit over five scoreless innings and Steven Duggar hit his first home run in nearly two years to lead the San Francisco Giants past the Pittsburgh Pirates 3-1 on Thursday night.

DeSclafani (3-1) struck out five and walked one while improving to 3-7 against the Pirates. The lone hit off him was a first-inning single by Jacob Stallings.

Duggar's solo shot to right-center field with one out in the fifth off Wil Crowe (0-2) broke a scoreless tie. It was the center fielder's seventh career homer in four seasons, and first since June 13, 2019.

Duggar and Mauricio Dubon had two hits each for the Giants, who improved to an NL-best 23-14 with their fifth win in six games. Tyler Rogers earned his third save by pitching a scoreless ninth.

Pirates first baseman Will Craig hit his first major league home run with one out in the eighth off fellow rookie Camilo Doval. Craig's contract was selected from Triple-A Indianapolis earlier in the day after he went 5 for 6 with three homers in the previous two games.

The Giants added two more runs in the fifth after the home run by Duggar to stretch their lead to 3-0.

Mike Tauchman scored from third base on a low pickoff attempt by Stallings, the catcher. Mike Yastrzemski followed with a run-scoring triple past stumbling right fielder Gregory Polanco.

The Pirates have lost six of eight and were held to four hits.

Crowe allowed three runs and six hits in five innings with five strikeouts and one walk. The rookie is still looking for his first career win after seven starts.

Pirates: INF/OF Phillip Evans (left hamstring strain) was placed on the 10-day injured list. … RHP Sean Poppen was designated for assignment. … Double-A Altoona RHP Cody Bolton, a top prospect, underwent surgery to repair a torn meniscus in his right knee and will likely miss the remainder of the season.

Giants RHP Kevin Gausman (3-0, 1.97 ERA) faces Pirates LHP Tyler Anderson (3-3, 3.05) on Friday night. Gausman has pitched at least six innings in all seven starts this season. Anderson spent last season with San Francisco.
