PITTSBURGH (AP) — Logan Webb struck out 10 in six innings, and the San Francisco Giants hit three home runs on their way to an 8-1 victory over the Pittsburgh Pirates on Tuesday night.

Webb (10-8) allowed one run while scattering seven hits. It was his sixth double-digit strikeout game of the season.

Rookie Christian Koss and Willy Adames each hit a two-run homer and Jerar Encarnacion added a solo shot off rookie Mike Burrows as San Francisco won for just the third time in 11 games.

Koss opened the scoring with a drive into the left-field bleachers in the third inning. Encarnacion’s blast increased the Giants’ lead to 3-1 in the fourth, and Adames’ 18th homer of the season made it 6-1 in the fifth.

Encarnacion was playing his first game since June 15 after being sidelined by a strained left oblique.

San Francisco’s Patrick Bailey added a two-run single in the sixth inning.
