MILWAUKEE (AP) - Buster Posey hit a grand slam in the top of the 10th inning to lift the San Francisco Giants to a 10-7 win over the Milwaukee Brewers on Friday night.
Joe Panik singled, Mike Yastrzemski walked and Brandon Belt singled to load the bases for Posey who hit the first pitch from Matt Albers (4-3) to deep left-center. It was Posey's fifth career grand slam and first this season.
Keston Hiura, who had three hits, got his eighth homer of the season off Mark Melancon in the bottom of the 10th for the final margin.
Christian Yelich tripled off All-Star Will Smith (2-0) to start the bottom of the ninth and scored on Mike Moustakas' ground out to tie the game at 6. It was Smith's first blown save of the season, but he picked up the win thanks to Posey's fourth homer this season.
Trying to preserve a 5-4 lead, All-Star Josh Hader coughed up Tyler Austin's third career pinch-hit home run in the top of the eighth and then Brandon Crawford's first home run off a left hander this season with two outs in the ninth. Hader has allowed 17 hits, nine of them home runs, this season.
Rookie right-hander Shaun Anderson faced the Brewers for the first time and baffled them with four-seam fastballs, sliders and curveballs. He struck out a season-high eight, including NL MVP Yelich three times, but tired in the sixth.
A walk and a double by Moustakas ended Anderson's 11th career start. Reyes Moronta came on and gave up Ryan Braun's two-run double off the glove of third baseman Evan Longoria. Braun advanced on a wild pitch and scored on Thames' single to put the Brewers up 5-4.
Austin Slater's third home run of the season, a two-run shot in the fifth off Milwaukee starter Chase Anderson, evened it up for the Giants after the Brewers scratched out the game's first two runs.
Longoria's two-run blast in the sixth off Corbin Burnes hit the left-field foul pole and gave the Giants a 4-2 lead.
Giants: Manager Bruce Bochy said Madison Bumgarner was good to go for his Saturday start. The left-hander was knocked out of the game against St. Louis in his previous outing. José Martínez lined a wicked shot off Bumgarner's pitching elbow in the second inning last Saturday. X-rays were negative, but he had an elbow contusion.
Brewers: LHP Gio González (left arm fatigue) allowed two runs and four hits in two innings in his first rehab start on Thursday with Class-A Carolina.
Giants: LHP Bumgarner (5-7, 4.03 ERA) is 7-4 with a 2.76 ERA in 13 career starts against the Brewers, including 3-1 with a 3.31 ERA in five outings at Miller Park. It's the second time he's facing Milwaukee this season. He went six innings and took a no decision at Oracle Park in June.
Brewers: RHP Zach Davies (7-2, 3.07 ERA) makes his second start of the season against the Giants. He is 0-2 with a 2.81 ERA in three career outings against San Francisco, including a 5-3 loss at Oracle Park on June 14th.
