SAN FRANCISCO (AP) - Nate Schierholtz hit his second home run of the game leading off the bottom of the 14th inning to give the San Francisco Giants a 6-5 victory over the San Diego Padres on Wednesday night.
Schierholtz had three hits and drove in three runs for the Giants, who beat the Padres for just the third time in 12 games at AT&T Park.
Javier Lopez (4-1) threw two scoreless innings while Pat Neshak (1-1) took the loss.
Pablo Sandoval drove in three runs, including the game-tying runs in the eighth inning, as the Giants rallied from a three-run deficit. Andres Torres had three hits.
Sandoval's two-run double came against Mike Adams, who had not allowed a run in 15 of his previous 16 appearances against the Giants.
Ryan Ludwick drove in two runs, Chase Headley, Jesus Guzman and Rob Johnson all had one RBI for the Padres, who had won 10 of their last 13.
The Giants snapped a three-game losing streak.
Padres starter Dustin Moseley allowed four runs and five hits over 7 1-3 innings. He walked one and struck out a career-high nine.
Moseley was 1-3 over his previous eight games despite allowing no more than three runs in a game over that span. He has the lowest run support of any NL pitcher. Giants starter Madison Bumgarner has the second-lowest.
Bumgarner lasted six innings, allowing five runs and nine hits. He walked one and struck out six. He is 1-5 in nine starts at home.
Ludwick had a two-run double in the first, but Torres doubled leading off the home half of the inning and eventually scored on Sandoval's groundout.
The Padres added a run in the third on Headley's sacrifice fly and in the fourth on Guzman's double.
Schierholtz's fifth home run of the year, a two-run shot that glanced off the right field foul pole, narrowed the deficit to 4-3.
Orlando Hudson singled with two outs in the sixth, stole second and advanced to third on Chris Stewart's throwing error. He scored on Johnson's single to make it 5-3.
Torres sparked the tying rally with a one-out single off Moseley. Adams came in and allowed Brandon Crawford's single ahead of Sandoval's drive into the right-center field.
