SAN FRANCISCO -- Through the first 10 games of the season, the Giants leaned on their starting rotation to pick up their sluggish offense. On Tuesday night, their bats finally got the chance to return the favor.

Mike Yastrzemski, Brandon Crawford and Evan Longoria homered to erase an early four-run deficit and power the Giants to a 7-6 comeback victory over the Reds, evening this three-game series at Oracle Park.

Wilmer Flores drove in the game-winning run for San Francisco, lifting a sacrifice fly to center field to score Donovan Solano from third and snap a 6-6 tie in the bottom of the seventh.

Submariner Tyler Rogers confounded hitters in a clean eighth, and closer Jake McGee worked a scoreless ninth to convert his fifth save of the year and lock down the back-and-forth affair for the Giants.

San Francisco entered Tuesday batting only .192, but manager Gabe Kapler expressed confidence that the lineup would begin to click as expected soon. That offensive breakout finally happened on Tuesday, with the Giants setting season highs in hits (11) and runs scored.

“I think what tonight demonstrated is that we are resilient, and we’re not going to get down on ourselves,” Kapler said. “We’re not going to lose confidence because we have a stretch of 10 or sometimes even more games where we’re not putting up big numbers. It’s just the ebb and flow of baseball. We have to be even through those times and be resilient and fight through them so that we come out on the other end and things start to click. The only way we do that is through maintaining our confidence and staying patient.”

The Giants trailed, 4-0, after Joey Votto and Mike Moustakas each launched two-run home runs off right-hander Kevin Gausman in the top of the first, but they quickly wiped away the deficit after Yastrzemski and Crawford countered with a pair of two-run shots of their own off Reds ace Luis Castillo in the bottom half of the inning.

It marked the first time four or more home runs have been hit in the first inning of a game at Oracle Park, according to the Elias Sports Bureau.

The Reds went ahead, 5-4, on Nick Castellanos’ RBI double in the second, but Gausman settled in after that and ended his outing by retiring the final 13 batters he faced. He departed after allowing four hits, walking two and striking out seven over six innings.

“Longo kind of told me, ‘Hey, keep your head down, keep going, keep grinding. We’re going to win this game,’” Gausman said. “With these guys, you feel pretty confident that eventually they’re going to get the job done.”

Fittingly, Longoria tied the game with his fourth home run of the year in the bottom of the sixth. Buster Posey then kept the two-out rally alive with a single to left field. With lefty reliever Sean Doolittle on the mound for the Reds, Kapler sent Austin Slater to pinch-hit for LaMonte Wade Jr., prompting Reds manager David Bell to summon right-hander Carson Fulmer from the bullpen.

Kapler decided to stick with Slater, who promptly tripled to right-center field to score Posey from first and give the Giants a 6-5 lead.

“I thought we did a really nice job of spoiling tough pitches,” Kapler said. “I thought we did a really nice job of extending at-bats. I thought we got some really timely and important hits. I thought our offense looked really good today, from both sides. We kind of made a little line change there midgame, and our right-handed bats came through in a pretty big way as well.”

Still, the Reds once again tied the game in the top of the seventh, when Jonathan India reached on an infield single and advanced to third on a balk and a wild pitch by left-hander Wandy Peralta. Tyler Blandino followed with an RBI bloop single that eluded both Crawford and La Stella, who collided in shallow center field while trying to snag the ball.

La Stella was 3-for-3 out of the leadoff spot at that point, but Kapler decided to have the right-handed-hitting Solano pinch-hit for him against lefty Cionel Pérez to start the seventh. The move paid off, as Solano drew a walk and later came around to score the decisive run for the Giants.

“It’s a huge credit to those guys,” Yastrzemski said. “That’s a really hard thing to do, to be thrown into the game to pinch-hit, to have those at-bats in those big situations and to produce. It’s really hard to do. It’s really impressive that we have the ability to do that. It’s a credit to our bench because everybody should be playing every day. That’s the crazy thing about our lineup. Our guys are that talented.”
