Giants 4, Brewers 3 (14): Hector Sanchez homered with one out in the top of the 14th inning, lifting visiting San Francisco in the series opener.

Sanchez unloaded on Juan Perez (0-1), Milwaukee's sixth pitcher, to give the Giants their fourth win in five games.

Buster Posey, who was replaced by Sanchez as part of a double switch in the 12th, belted a three-run homer in the first inning for San Francisco's other runs.

Javier Lopez (4-0) worked one-third of an inning for the win and Santiago Casilla finished up for his 11th save.

Reigning National League MVP Ryan Braun belted a two-run tying home run in the eighth inning to spoil a magnficent outing by Giants starter Madison Bumgarner.

Braun, who extended his hitting streak to 10 games and has nine RBIs during a stretch of four straight multi-hit games, exited in the 10th inning due to right groin tightness.

Bumgarner had registered a season-high 10 strikeouts and was on cruise control until a two-out error by shortstop Brandon Crawford in the eighth inning opened the door for Braun's blast.

Brewers starter Randy Wolf blanked the Giants for six innings after giving up Posey's homer in the first. He allowed three runs on five hits.
