SAN FRANCISCO -- Jay Bruce belted a solo home run off Madison Bumgarner to snap a tie in the seventh inning to lift the Cincinnati Reds to a 2-1 victory over the San Francisco Giants in the finale of a three-game series Wednesday.

Right-hander Dan Straily limited the Giants to three hits in 7 2/3 innings in his AT&T Park debut, helping the Reds win for the second time in three days in San Francisco. Cincinnati recorded its fourth consecutive series win since the All-Star break.

Straily outdueled Bumgarner, who was pitching at home for the first time since his near-no-hitter on July 10 against the Arizona Diamondbacks.

Bumgarner (10-6) had allowed only three hits in six innings before Bruce smacked his first pitch of the seventh well over the right-field wall for his fourth homer of the series and sixth in five games. The blast, which gave the Reds a 2-1 lead, marked his first career extra-base hit versus Bumgarner.

Bruce has homered in a career-high five straight games. He became the sixth Red ever to do so, the previous being catcher Devin Mesoraco in 2014.

The subject of serious trade talk with the deadline approaching, Bruce had entered the game just 2-for-17 (both hits singles) in his career against Bumgarner.

That slump went to 2-for-19 after a pair of flyouts in his first two at-bats Wednesday.

Bruce's four homers in 13 at-bats in the series came after he'd hit only two previously at AT&T Park in 81 at-bats.

Straily (6-6) gave up a third-inning homer to Conor Gillaspie, but only two other hits before getting pulled with two outs in the eighth.

He walked one and struck out five in his 90-pitch effort.

Right-hander Raisel Iglesias retired Gregor Blanco on a ground ball with a runner on base to end the eighth, and closer Tony Cingrani pitched around a leadoff single by Angel Pagan in the ninth for his 12th save and the Reds' 14th win in their last 19 visits to San Francisco.

The Reds improved to 8-4 since the All-Star break.

Bumgarner completed eight innings, allowing two runs, only one of which was earned. He gave up five hits, struck out nine and did not walk a batter.

The outing was his 28th straight at home in which he's gone at least five innings and allowed no more than three earned runs. That streak is the longest by a Giants pitcher since 1913.

The All-Star had recorded 19 consecutive scoreless innings at home before the Reds scored an unearned run in the fifth.

After Gillaspie's homer had put the Giants in front, the Reds got even thanks in large part to a Pagan error.

Tucker Barnhart's sacrifice fly scored Brandon Phillips, who had singled with one out, to tie the game. Phillips advanced into scoring position on Eugenio Suarez's liner to left field that was dropped for a two-base error by Pagan.

Joey Votto had two of Cincinnati's six hits, extending his hitting streak to 12 straight games since the All-Star break.

Votto's run of nine consecutive games with a walk ended, however, on a 2-for-4 day.

Gillaspie's home run came after Straily had retired the first six Giants. It was his fourth of the season and survived a video review that assured that the ball had cleared the 20-foot-high barrier in right-center field.

Pagan had two hits for the Giants, whose record fell to 2-9 since the All-Star break.
