Giants 4, Braves 1: Brandon Crawford notched his first career two-homer game and Madison Bumgarner fanned nine over six dominant innings as San Francisco completed a three-game sweep in Atlanta for the first time in nearly 26 years.

Crawford recorded a solo shot off Alex Wood (2-5) in the fourth inning to break up a 1-1 tie and added a two-run blast in the eighth as San Francisco posted its first three-game road sweep against the Braves since June 27-29, 1988. Bumgarner (3-3) avoided losing four straight starts for the first time in his career, allowing only an unearned run on three hits and a walk.

Chris Johnson had a pair of singles to account for half of Atlanta’s four hits while Jason Heyward drove in Ramiro Pena on a sacrifice fly as the Braves were held to one run in every game of this series. Wood struck out seven but took the loss after yielding two runs and seven hits over five innings.

San Francisco struck first in the opening frame as Hunter Pence doubled with one out and advanced to third on a wild pitch before coming across on Buster Posey’s RBI groundout. Atlanta manufactured its only run in the third when Pena singled, moved to third following a sacrifice bunt by Wood and throwing error by Bumgarner and scored on Heyward’s fly ball to center.

The Giants homered for the 11th consecutive game in the fourth when Crawford hammered a 1-2 fastball down the middle of the plate into the seats in right-center. Crawford went deep again four innings later off reliever Jordan Walden to give San Francisco some insurance runs while three relievers bridged the gap from Bumgarner to Santiago Casilla, who filled in for closer Sergio Romo after he worked the Giants’ last three games, and tossed a perfect ninth for his first save in four chances.

GAME NOTEBOOK: Eight of the San Francisco’s nine runs in this series came via the home run, including seven solo shots. … The Giants’ 11-game streak of hitting at least one home run is their longest since a 14-game run from July 28-Aug. 13, 2002. … Atlanta activated RHP Gavin Floyd from the 15-day disabled list on Sunday and optioned LHP Ian Thomas to Triple-A Gwinnett.
