SAN DIEGO -- Evan Longoria is currently sidelined with a left oblique injury, but he still found a way to deliver a huge hit on Saturday.

With the Giants in the midst of one of their worst stretches of the season, Longoria decided to try to lighten the mood in the clubhouse by organizing a pregame home run derby at Petco Park. The competition appeared to have the intended effect, with players breaking out in big smiles and cheers as they watched Austin Slater beat Austin Wynns in the final round.

The good vibes carried over to Sunday afternoon, when the Giants erupted for 17 hits in a 12-0 blowout that secured a split of their four-game series against the Padres. San Francisco played one of its most complete games in weeks, with Thairo Estrada and Wilmer Flores each crushing two-run shots off National League Rookie of the Year contender MacKenzie Gore and lefty Alex Wood firing seven shutout innings in his best start of the year.

“Losing sucks,” Wynns said. “We’re trying to keep a good atmosphere in this clubhouse, especially on the field with everything going on. We need to make sure the clubhouse is solid, and it is. We’re going to keep on taking steps forward to do that. If you’re around positive people, positive energy, you play better.”

After a 4-14 slide, the Giants have now won back-to-back games for the first time since June 17-18 against the Pirates.

“The boys came out banging today, we played good defense and we threw the ball well,” Wood said. “It was a good team win overall. Hopefully we’ll gain some momentum going into the last week for the All-Star break and get back to where we need to be.”

Flores also homered off infielder Matthew Batten, who took the mound for the Padres in the ninth, to cap his four-hit, four-RBI game and collect his third blast in his last two games.

“I was more nervous on my last one,” said Flores, who ranks second on the club with 12 homers this year. “You don’t want to make an out against a position player. But I went all in. I tried to hit a homer.”

Slater, Estrada, David Villar, Mike Yastrzemski and Luis González each produced multiple hits to help the Giants score double digits for the first time since June 21 at Atlanta. Entering Sunday, they’d been held to fewer than 10 hits in 14 consecutive games, their longest drought in a single season since Sept. 14-30, 1999.

Manager Gabe Kapler said he thought Saturday’s derby was a good way to remind players that they can still have fun and remain relaxed even while weathering turbulence on the field.

“I think that we need to be as loose and as calm as possible at all times,” Kapler said. “I think we need to keep things as light as possible whenever we can because we prepare so diligently, we work so hard, and there needs to be some balance between the work and the play. Everyone enjoyed it. … If guys are laughing, something good is happening.”

Despite their recent struggles, the Giants have largely remained committed to the processes that helped them win a franchise-record 107 games last year. With the left-handed Gore on the mound on Sunday, they decided to sit the majority of their lefty hitters, including All-Star Joc Pederson and veterans Brandon Crawford and Brandon Belt.

But their right-handed lineup got the job done against Gore, with Estrada opening the scoring with a two-run blast in the second. It was Estrada’s seventh home run of the year and his first since returning from a stint on the COVID-19 injured list on Friday. Flores stretched the lead to 4-0 with another two-run homer in the third before the Giants broke the game open with a four-run rally in the fourth.

It turned out to be plenty of support for Wood, who followed Carlos Rodón’s 12-strikeout complete game with another three-hit gem on Sunday. Wood retired 14 in a row after issuing a one-out walk to Manny Machado in the first inning and didn’t allow a hit until C.J. Abrams singled to left field to start the sixth. Wood struck out eight and issued only one walk while racking up 14 whiffs, including seven on his slider.

“I think it was one of the better pitching performances of Wood’s career,” Kapler said. “I think that’s objectively true. But also, the eye test. It looked like he had his best slider of the year.”

The Giants have struggled to consistently get quality starts from starters other than Rodón and Logan Webb this year, but Wood’s performance is an encouraging sign that the rest of the rotation is beginning to perk up as the club heads back to San Francisco to host the D-backs and the Brewers in its final homestand before the All-Star break.

“Hopefully it means a lot more good starts to come,” Wood said. “To be able to come back today and give seven quality innings and get out of here with a split series was big for us, for sure.”
