SAN FRANCISCO-There maybe one more game in the Bay Bridge Series, but the San Francisco Giants have already clinched if after the two games.

Madison Bumgarner pitched seven strong innings, allowing one run on just five hits, walking two and striking out seven and the Giants defeated the a Oakland A’s 2-1 before a crowd of 42,186, the 376th consecutive sellout at AT&T Park.

With the victory, the Giants 10 out of their last 11, while the A’s gave lost four out of their last five games.

Over his last 11 games at home Bumgarner has allowed two or fewer runs in eight of those starts.

Bumgarner was also big at the plate as well, as he took a Chris Bassitt pitch and put it into the left field bleachers in the bottom of the third inning that gave the Giants 1-0 lead over their Bay Area counterparts.

It was the third home run of the season for Bumgarner, and the ninth of his career.

Bumgarner was the first opposing pitcher to hit a home run off the A’s since Dave McNally of the Baltimore Orioles did it off of Ken Holtzman in 1972.

Bassitt went six innings, allowing two runs on five hits, not walking a batter and striking out four, as he falls to 0-3 on the season.

Matt Duffy drove in what turned out to be the winning run in the bottom of the sixth inning, as with two outs, Joe Panik doubled up the right-center field gap and then Matt Duffy singled in Panik with what proved to be the winning run.

In his four starts this season, Bassitt receives an average of 1.57 runs per game during the four starts.

After Bumgarner’s home run in the second inning, the A’s tied it up in the top of the fourth inning, as Jake Smolinski singled and then Josh Phegley tied up the game with a double to left field.

Buster Posey saw his nine-game hitting streak come to an end, as he went 0-for-3 on the afternoon.

Santiago Casilla picked up his 25th save of the season, tying his career high that was set during the 2012 season.
