Madison Bumgarner got run support in the very first inning from his battery mate, and the San Francisco Giants never looked back.

Andrew Susac hit a two-run double in the first inning, as the Giants scored four runs in the opening inning and hung on to defeat the Detroit Tigers 5-4 at Comerica Park.

Buster Posey continues his late push for National League Most Valuable Player award, as he picked up three hits on the afternoon, including a solo home run for the Giants who have won nine out of their last 11.

Bumgarner pitched six strong innings for his fourth consecutive victory and his career-high 17th victory of the season

The left-gander failed to walk or a strikeout for the first time in his major league career.

Miguel Cabrera hit two home runs for the Tigers, giving him 20 for the season, while Victor Martinez hit a solo home run in the bottom of the third inning, that gave him a career-high 30 home runs on the season.

David Price came back after a rough first inning to pitch eight and two-thirds innings, as he struck out 11.

Posey hit his 20th home run of the season in the top of the fifth inning to give the Giants a two-run lead.

Cabrera got a little redemption when hit his home run in the bottom of the eighth inning, as he hit his home run off of Sergio Romo, who struck out the 2012 American League Triple Crown winner to clinch the Giants second World Series championship in the last last three years.

This was the second multi-home run game for Cabrera of the season, with both of them occurring this week.
