SAN FRANCISCO — No-hit through six innings, the Giants’ bats came alive late to rally for a 3-2 walk-off win over the Tigers in Friday night’s series opener at Oracle Park.

Beau Briske and Kenta Maeda shut down the Giants’ lineup until Tyler Fitzgerald finally broke up the combined no-hit bid with a leadoff single in the seventh. Fitzgerald went from first-to-third on another base hit by Heliot Ramos and then scored on Michael Conforto’s sacrifice fly to cut the deficit to 2-1.

The Giants tied the game on another sacrifice fly by Patrick Bailey in the eighth and then completed their comeback in the bottom of the ninth. Mark Canha, who was acquired from the Tigers at the Trade Deadline last week, lifted another sac fly with the bases loaded to score Conforto from third and end the game, giving the Giants (60-58) their 12th win in their last 16 games.

Robbie Ray gave up two runs on five hits over six innings in his fourth start of the year for the Giants. The 32-year-old left-hander walked three and struck out seven while throwing a season-high 105 pitches.
