SAN FRANCISCO-Madison Bumgarner did it all by himself in the series finale against the Chicago Cubs.

Bumgarner drove in the only run of the game on a double that scored Gregor Blanco from first base in the bottom of the fourth inning, as the San Francisco Giants defeated the Cubs 1-0 before 41,359, the 432nd consecutive sellout at AT&T Park.

The duo of Matt Cain and Bumgarner became the first Giants pitchers since May 29 and 30, 1978 to drive in the game-winning runs in back-to-back games. Ed Halicki singled in the game-winning run on May 29, and then Bob Knepper turned the trick with a sacrifice fly on May 30, this according to STATS, INC.

Not only did Bumgarner drive in the only run for the Giants, but his outing on the mound was solid. Things did not begin well for Bumgarner, as he threw 28 pitches in the first inning alone and the Cubs loaded the bases; however Bumgarner got out of the jam, when struck out Addison Russell looking to end the inning.

This was the first time in Bumgarner’s career that he won a game with just one run of support, as the Giants are now 2-27 in such games with Bumgarner on the mound. This was the first time that the Giants won a game with just one run of support for Bumgarner since July 1, 2011 against the Detroit Tigers at Comerica Park.

Bumgarner is the second pitcher this season to drive in the only run of the game and come out with the win, the other pitcher is Clayton Kershaw of the Los Angeles Dodgers.

After that first inning, where he hit a batter, gave up a base hit and walked a batter, the 26-year old left-hander gave up only two hits until he was replaced by Cory Gearrin with two outs in the top of the eighth inning.

Gearrin threw one pitch to Kris Bryant, and the reigning National League Rookie of the Year lined out to Brandon Crawford at shortstop.

Just prior to Bryant lining out to Crawford to end the inning, Anthony Rizzo walked and that was the end of the night for Bumgarner.

In all, Bumgarner went 7.2 innings, allowing only three hits, walked two and struck out six in raising his record to 6-2 on the season.

Matt Szczur broke a streak of where Bumgarner retired 16 consecutive batters, when the right fielder singled with two outs in the top of the seventh inning; however Bumgarner regrouped and struck out David Ross to end the threat and the inning.

Blanco walked to leadoff the inning where the Giants scored their only run of the game on the Bumgarner double.

Despite being on the short end of the 1-0 loss to the Giants, Kyle Hendricks pitched a great game for the Cubs, as he went 5.1 innings, allowing just that one run on just three hits, while walking three and striking out one.

Santiago Casilla came on in the top of the ninth inning, and retired the Cubs in order to pickup his 12th save of the season.

This was the third time this season that Cubs have been shutout, as it also happened on April 17 versus the Colorado Rockies at Wrigley Field and on May 11 against the San Diego Padres also at Wrigley Field.

As for the Giants, this was the second time this season that they have thrown a shutout, as they also shutout the San Diego Padres 1-0 on April 26, as Johnny Cueto threw a complete game, the first of two against the Padres.
