Brandon Belt ripped a two-run pinch-hit homer and Tommy La Stella came off the bench to single home the game-winner as the San Francisco Giants rallied for a 5-4 victory over the host Milwaukee Brewers on Sunday.

Brandon Crawford doubled to open the eighth inning off Brad Boxberger (4-3). La Stella then battled back from two quick called strikes and capped an 11-pitch at-bat with a pinch-hit RBI single up the middle.

San Francisco, which leads the National League West and has the best record in baseball at 71-41, came from behind to win each of the final two games of the series against Milwaukee, which leads the NL Central.

Tony Watson (4-3) pitched a perfect seventh for the victory and Zack Littell worked the final two innings for his first save.

Belt brought San Francisco even at 4-4 in the seventh, driving a 1-1 pitch from Daniel Norris 412 feet to center for his 15th homer following a leadoff walk to LaMonte Wade Jr.

Belt, who had two homers in the Giants' wild 9-6, 11-inning victory Saturday night, has four homers and seven RBIs in four games since coming off the injured list. He has 15 for the season.

Darin Ruf hit his 13th, a solo homer in the first inning, for the Giants, who lead the majors with 169 homers. San Francisco has eight players with 10 or more homers, the most of any team in the majors.

Omar Narvaez put Milwaukee up 2-1 in the fourth with a two-run homer, his 10th. Johnny Cueto retired the first 10 hitters before Christian Yelich drew a one-out walk. After Eduardo Escobar fouled out, Narvaez drove a 1-1 pitch 415 feet to right center.

The Brewers added a run in the fifth when Jackie Bradley Jr. singled with one out. He advanced on an errant pick-off attempt, took third on a groundout and scored on Kolten Wong's single.

The Giants pulled within 3-2 in the sixth on Crawford's bases-loaded sacrifice fly.

Milwaukee got the run back in the bottom half when Escobar doubled, advanced on a ground out, and scored on a wild pitch by Jose Alvarez.

Brewers starter Brett Anderson allowed one run on five hits in five innings before departing with left calf cramping. Cueto pitched 5 1/3 innings and allowed four runs on five hits with three strikeouts and a walk.
