SAN FRANCISCO (AP) -- Madison Bumgarner had a season-high 12 strikeouts and hit his first major league home run to lead the San Francisco Giants to a 6-3 victory over the Houston Astros on Tuesday night.

Bumgarner connected on a 2-1 pitch from Houston starter Bud Norris leading off the third inning. It's the first home run by any San Francisco player at AT&T Park since May 14.

Brandon Belt added a two-run homer, Brandon Crawford drove in two runs and Melky Cabrera had two hits and an RBI in his return to the Giants lineup.

Brian Bixler singled, doubled and drove in both runs for Houston, which has lost 12 of its last 16 games.
