PHOENIX -- Pablo Sandoval defies convention on the baseball field, so it makes perfect sense that he would put his own twist on a called shot.

With the Giants trailing the Arizona Diamondbacks by a run in the ninth inning Tuesday, Sandoval and Hunter Pence had a short discussion in the dugout. Pence told Sandoval to "feel that good click" at the plate, and the fun-loving Panda told Pence he would "click one" and then started singing Kanye West's "Clique" as he walked to the plate.

Moments later, he hit a mammoth blast to right field, leading the Giants to a 2-1 come-from-behind victory that capped a month of improbable comebacks.

Did Sandoval call his shot during the conversation with Pence?

"Pretty much," he said, smiling.

Pence said he was "simply trying to plant the seed" for a game-winning homer, and in that respect, the right fielder was doing nothing out of character. Known as Reverend Pence last postseason, Pence's pregame speeches planted the seeds for a string of historic comebacks.

The never-say-die attitude still hasn't dissipated.

Despite poor starting pitching at times, an inconsistent lineup and uncharacteristic play in the field, the Giants won 15 April games for the first time since 2003.

"It seems like we've been struggling and having a hard time, but we've pulled out wins," Madison Bumgarner said. "As long as we keep fighting and getting wins, that's all you ask for."

The Giants couldn't have asked for much more from Bumgarner on Tuesday. He threw seven shutout innings to become the first Giants pitcher with at least six starts of two or fewer runs since Kevin Correia had seven in 2007.

Bumgarner finished April with a 3-0 record and 1.55 ERA, the second-lowest mark in the National League.

"He's doing what we need: putting up zeros," Bochy said. "He's in a good place right now."

Opposing starter Trevor Cahill was in a good place, too. Cahill needed just 82 pitches to get into the ninth inning but ran into immediate trouble when Angel Pagan singled. Cahill was replaced by closer J.J. Putz, and Pagan stole second.

All the while, Sandoval and Pence were talking about what was to come.

Sandoval had been removed from Monday night's game with right elbow irritation but arrived at the ballpark early Tuesday and convinced trainer Dave Groeschner that he was fine.

"You want to keep playing," Sandoval said. "I don't pay attention to (the soreness)."

When he stepped to the plate with one out in the ninth inning, Sandoval had 10 hits in his previous 16 at-bats. Eight of them were singles, but as soon as Sandoval hit Putz's splitter, there was no doubt about where it would land. The ball finally touched down more than a dozen seats beyond the pool behind the right-center field wall.

When Josh Wilson had homered in the eighth to give the Diamondbacks the lead, he flipped his bat toward the Giants dugout. Sandoval followed his blast with an emphatic bat flip of his own and then started the jog around the bases.

  • Sergio Romo closed out the Diamondbacks in the ninth to pick up his 10th save of the month. Romo's career-high before this season was 14.

    "I didn't see him having 10 saves (in April)," Bochy said. "That's not an easy save. A one-run game, facing the heart of their order. He did a great job."

    Romo, an Arizona resident, has pitched 26 consecutive scoreless innings against the Diamondbacks dating to 2010.

  • Buster Posey's hit streak was snapped at 10 games.

  • Sandy Rosario got the last out in the eighth on three pitches to earn the first win of his career.

  • Reliever Jeremy Affeldt (oblique strain) will face hitters during an extended spring training game Wednesday. Affeldt is likely to come off the disabled list when the Giants return to AT&T Park on Friday.
