Logan Webb struck out 10 and allowed one run over six innings to lead the San Francisco Giants to an 8-1 victory over the host Pittsburgh Pirates on Tuesday night.

Webb (10-8) put together his second consecutive solid start in less than a week against the Pirates to score the Giants' first win in five tries this season against Pittsburgh. It was Webb's sixth start with 10 or more strikeouts. He allowed seven hits and one walk.

Bryan Reynolds had two hits to lead the Pirates, who had a brief two-game winning streak snapped and lost for only the fourth time in their past 14 games.

Christian Koss hit a two-run home run to center field off Pirates starter Mike Burrows (1-4) in the third inning to open the scoring.

Pittsburgh answered in the bottom of the inning when Reynolds singled with the bases loaded and one out to score Isiah Kiner-Falefa and cut the deficit to 2-1. But Oneil Cruz struck out and Nick Gonzales grounded out to end the threat.

Jerar Encarnacion, who was called up from the minors on Monday, hit his first home run of the season in the fourth to extend the Giants' lead to 3-1.

San Francisco broke the game open in the fifth with three more runs. Rafael Devers singled to drive in Heliot Ramos, who started a two-out rally with the second of his two hits.

Willy Adames, who also had two hits, followed with a two-run home run off Burrows to push the Giants' lead to 6-1. Every starter in San Francisco's lineup recorded at least one hit.

Burrows' three homers allowed were a career-high, and he walked three, struck out three and gave up six runs and five hits over 4 2/3 innings. It was Burrows' worst start in his rookie season since he also allowed six runs against the Minnesota Twins on July 12.
