SAN FRANCISCO -- It was truly a tale of two games Wednesday for the Padres, who encountered very few difficulties during the first seven innings of their game against the Giants at AT&T Park.
The final seven innings were a much different story, especially the last inning when Nate Schierholtz hit his second home run of the game, a walk-off blast in the 14th inning, to lift the Giants to a 6-5 victory over the Padres in front of a sold-out crowd.
Schierholtz's home run came off Padres reliever Pat Neshek (1-1).
The Padres were six outs away from winning their third game in as many days against the National League West-leading Giants (49-39) before Pablo Sandoval tied the game in the eighth inning with a two-run double off reliever Mike Adams.
"I'm very disappointed in myself," Adams said. "I consider myself one of the best if not the best [reliever] in the game. I'm very upset. That shouldn't have happened."
The Padres (40-48) scored five runs through the first six innings Wednesday, chasing Giants starting pitcher Madison Bumgarner almost in the same fashion they did the prior two games against Tim Lincecum and Matt Cain.
But that 5-3 lead, thanks in large part to the pitching of Dustin Moseley, didn't stand up. Moseley set a career high with nine strikeouts in 7 1/3 innings, allowing four runs to go with five hits and one walk before leaving with one out and one on in the eighth inning.
"I was getting ahead in a lot of counts," Moseley said. "I had good command of the cutter and my curveball. I had a sharp hook. I'm always surprised when I have that many strikeouts but I was able to keep my pitch count down.
"That was good."
The same couldn't be said for the Padres' offense after the Giants rallied to tie the game, as San Francisco relievers combined to retire the final 17 hitters they faced beginning in the ninth inning after Jason Bartlett's hit-and-run single.
"We couldn't get anything going," Padres manager Bud Black said. "That was two good bullpens going at it."
The Padres and Giants combined for 36 strikeouts, including 19 by the Padres. That's the Padres' most strikeouts in a game since May 25, 2008, against the Reds when they also had 19 in an 18-inning game.
"Our bullpen really shuts the door, so we feel like if we can get someone in scoring position, that's our goal -- just to get the first guy of the inning on and hopefully get him in," said Schierholtz, who had a two-run home run in the fourth inning.
Early on, it was the Padres swinging the bats.
Bumgarner got off to a rough start and his night never really improved as Ryan Ludwick had a two-run double to the gap in left-center field to score two runs in the first innings -- RBIs Nos. 53 and 54.
That was only the start, though, as the Padres stressed Bumgarner by getting at least one runner on base in each of his six innings and scoring at least one run in four of those first six innings.
Leadoff hitter Chris Denorfia doubled to start the third inning and scored from third base on Chase Headley's sacrifice fly later in the inning.
One inning later, the bats -- and legs -- of speedy Cameron Maybin helped account for a run, as Maybin tripled for the second time in as many games. He later scored on an RBI double by Jesus Guzman, who started at first base against Bumgarner.
The final blow for Bumgarner came in the sixth inning when Rob Johnson, who struck out in his previous two at-bats Wednesday, lined an RBI single to center field with two outs to give the Padres a 5-3 lead.
Across the way, Moseley was mostly cruising. He gave a run back in the bottom of the first inning and then two more on one swing of the bat in the fourth inning, when Schierholtz pounded a 3-1 changeup off the foul pole.
That was the last run Moseley would allow, as he pitched into the seventh inning before giving way to Adams.
"He pitched great. He was efficient and threw pitches into the eighth inning," Black said.
