OAKLAND -- LaMonte Wade Jr. earned his “Late Night” nickname due to his penchant for clutch ninth-inning hits last season, though one of his signature moments took place on an afternoon at the Oakland Coliseum.

On Aug. 21, 2021, Wade came off the bench to crush a go-ahead two-run shot off A’s closer Lou Trivino in the ninth, powering the Giants to a dramatic comeback victory that helped them stay in front of the Dodgers in the tightly contested National League West.

Wade has struggled to match those heights this year. But the 28-year-old slugger channeled his 2021 form in his return to the Coliseum on Saturday afternoon, going 2-for-4 with two RBIs to help the Giants snap a four-game skid with a 7-3 win over the A’s in the Bay Bridge Series opener.

Wade, batting eighth and serving as the designated hitter, doubled in his first at-bat in the second inning before teaming up with recently acquired utility man J.D. Davis to launch back-to-back blasts that broke the game open in the sixth. It was only the third multihit game of the season for Wade, who entered Saturday batting .172 with a .620 OPS over 34 games this year.

“Very encouraging,” manager Gabe Kapler said. “These are the guys that we’re going to need to perform if we’re going to the postseason. It’s going to be a lot of consistent and especially good performance. I think that’s what we saw today.”

Wade emerged as the Giants’ breakout hitter in 2021, when he recorded an .808 OPS with 18 home runs over 109 games. But his second season in San Francisco has been marred by a left knee injury that cost him 61 games and led to two separate trips to the injured list. Wade returned from his second IL stint on June 29, but he had a difficult time finding his rhythm at the plate, going only 9-for-62 (.145) over his first 24 games.

“We’ve been working on some stuff in the cages,” Wade said. “Things have been feeling better as of late, so we’ve just got to keep rolling and keep going with it.”

Wade looked more like himself on Saturday, grinding out an eight-pitch at-bat against Oakland right-hander Adam Oller in the second before lifting a changeup into the right-center-field gap for a leadoff double. He added his fourth home run of the year in the sixth, drilling a fastball out to right field to stretch San Francisco’s lead to 4-1 and knock Oller from the game.

After lefty Kirby Snead entered in relief, the Giants sent up the right-handed-hitting Davis to pinch-hit for Tommy La Stella. Davis promptly hammered a first-pitch sinker out to straightaway center for a mammoth, Statcast-projected 437-foot shot, his second home run in three games since being acquired from the Mets as part of the Darin Ruf trade on Tuesday.

There were several other positive developments for the Giants, who also welcomed outfielder Joc Pederson and shortstop Brandon Crawford back into their lineup on Saturday.

Pederson, who slotted into the leadoff spot in his first game back from a concussion, set the tone by drawing a free pass and scoring on Crawford’s bases-loaded walk to put the Giants on the board in the first inning. Pederson also knocked in Wade with an RBI single in the second, while Crawford added a two-out double in the third after missing 16 games with left knee inflammation.

“I don’t think there’s any question that when our lineup is deep and healthier, it feels like we have a chance to put runs on the board,” Kapler said.

The Giants also got another encouraging performance from rookie Joey Bart, who capped the club’s offensive output with a seventh-inning solo shot off Snead. Since returning from the Minors on July 6, Bart is batting .282 (20-for-71) with five home runs over 24 games, and he has reeled off three consecutive multihit games.

Better health and more consistent production will be key for the Giants as they attempt to rebound from a 3-12 slide that left them seven games behind the Phillies for the third and final NL Wild Card spot. Saturday was a step in the right direction, but the Giants know they have plenty of work ahead of them if they plan to reassert themselves as true contenders over the final two months of the regular season.

“We’re starting to click a little bit on both sides of the ball,” Wade said. “We’ve got some guys who were hurt doing some big things, so it always helps getting those guys back. Anytime we’re at full health, I think we’re pretty good.”
