sixth inning

SAN DIEGO — The home run that Roki Sasaki gave up to San Diego’s Ty France was more dramatic than the two walks he issued to open the inning. But it was the free passes that really hurt him.

In the Dodgers’ 7-1 loss to the Padres on Friday, Sasaki was out of the game before he could record an out in the fifth inning. He gave up only three hits but issued five walks, tying his season high, and hit a batter.

“I actually felt different than I ever felt before, mechanically,” Sasaki said through interpreter Kensuke Okubo, noting that his lower body felt a little off. “So I need to go over it and see what was really happening.”

Sasaki successfully pitched around traffic for much of his outing, other than the three-run homer to France in the second inning. But the inefficiency sent his pitch count past 80 before he exited with runners on first and second in the fifth.

“I’m not going to have it every time out, so that’s something I have to improve,” Sasaki said. “And also the game plan. I was able to execute some of the pitches, but some of the pitches I couldn’t, so that’s something I have to go through before next start.”

Earlier this month, when Sasaki held the Angels scoreless through seven two-hit innings, it seemed as if he’d had a breakthrough. But in three starts since, including a seven-run dud against the Chicago White Sox two weeks ago, he has yet to pitch through the sixth inning.

“I am a little surprised, because there was such good momentum going on,” manager Dave Roberts said. “Hopefully we can get him back to throwing the way he did in May.”

Sasaki’s command issues Friday showed up almost immediately. After striking out Padres leadoff hitter Fernando Tatis Jr., Sasaki walked Samad Taylor on 10 pitches. But Sasaki bounced back by inducing a double play.

The next inning, there would be no such escape. Sasaki walked both Manny Machado, whom he also battled for 10 pitches, and Gavin Sheets to open the frame. Then Xander Bogaerts’ sharp line drive to center field found leather.

France’s long fly ball to left field, however, found the seats.

Sasaki’s only clean inning, the third, was made possible by catcher Dalton Rushing’s successful challenge of a called ball four against Tatís, flipping a walk into a strikeout.

“I know that there’s confidence in there,” Roberts said. “But when you feel good and you don’t feel good mechanically and can’t execute pitches, then the results are walks, and 1-2 [count] homers, and things like that. But I do think that we can kind of tackle the mechanical things that he’s probably looking for right now.”

The Padres piled on in the eighth inning against reliever Jonathan Hernandez, as the sold-out crowd chanted “Beat L.A.!”

Mookie Betts hit a home run off former teammate Walker Buehler for his second homer in as many games. Betts seems to have come out of his offensive funk, entering Friday with a 1.061 on-base-plus-slugging percentage over the previous 11 games.

Buehler earned the win, delivering five strikeouts in 5⅓ innings.

“[Buehler] is reinventing himself,” Roberts said. “He’s throwing the kitchen sink at you. Cutter, slider, changeup, two-seamers. He doesn’t just try to bully you, and he’s finding ways to just get guys out. So yeah, he’s gonna still go up there and compete.”

The Dodgers went 0 for 4 with runners in scoring position and squandered a bases-loaded opportunity with one out in the sixth inning after chasing Buehler. Max Muncy popped out and Kyle Tucker, back in the lineup after exiting Monday’s game because of back spasms, flied out.

The Dodgers have built such a big lead in the division that the loss barely made a dent. The Padres, in second place, trail by eight games.

CHAPEL HILL, N.C. — Dean Carpentier popped up with the biggest swing of his life, and the Trojans won their biggest game in more than two decades.

USC baseball stormed back to defeat No. 5 overall seed North Carolina 9-5 in Game 1 of the Chapel Hill Super Regional, a loud start to the program’s first appearance on this stage since 2005.

Carpentier smoked a go-ahead grand slam off North Carolina (48-12-1) reliever Walker McDuffie in the sixth inning, turning a 5-2 deficit into a 6-5 lead and shutting down a previously charged-up Boshamer Stadium. The swing was Carpentier’s first career grand slam and just his 10th home run in his 132-game collegiate career, the defining moment of the day as USC (48-16) tied its largest comeback victory of the season.

“I was sitting on a slider,” Carpentier said. “He’s a slider guy. I got a good pitch to hit, put a good swing on it and it found a way out of here.”

Ace Mason Edwards struggled through his shortest outing of the season, yielding three earned runs in just three innings with four walks. But the Trojan bullpen picked him up, and kept the game close enough for the offense to rally. Chase Herrell, Ben Cushnie and Andrew Johnson gave up just one run over six innings, with Johnson retiring the first eight batters he faced.

“He’s done that now a couple of times with the bases loaded where he strikes out the side and gets out of it,” USC coach Andy Stankiewicz said of Edwards’ first inning. “It’s in there. That was huge. It was a big momentum swing to get out of that. Unfortunately it’s taxing though; it made him jump up in his pitch count a little bit.”

His successful but ultimately draining first inning led to UNC scoring four in the next two innings, knocking the Trojans into a huge hole and forcing its bullpen to stem the tide. But eventual winning pitcher Herrell picked up two innings with just one earned run given up. Cushnie retired the only batter he faced and the offense went to work from there.

“The job that Chase Herrell did, the job he did in College Station, it’s two back-to-back outings where he has been tremendous for us,” Stankiewicz said. “It’s always Mason and Grant [Govel] — which is great, they deserve all the recognition — but there’s more guys down there that are doing it.”

With the lead and all of the momentum after Carpentier’s grand slam, Stankiewicz pushed his chips to the middle of the table knowing the importance of winning the opener of a best-of-three series. He brought usual Game 3 starter Johnson in out of the bullpen, and he delivered a sensational performance.

Johnson retired the first eight batters he faced and ended up getting the final 11 outs of the game with just two singles allowed, slamming the door shut for his first save of the season.

“You saw the job that he did over in College Station,” Stankiewicz said of Johnson. “It was a big moment, and we needed that again today. He throws strikes, he’s unafraid, he attacks the strike zone and we felt like he was going to make the pitches.”

Johnson’s dominance meant the go-ahead grand slam would have been enough, but USC added three more runs in the seventh. Isaac Cadena drove one in with an RBI groundout, Jack Basseer plated one on on a fielder’s choice and Andrew Lamb — who started the scoring for USC with a solo home run off Ryan Lynch back in the third inning — tacked on one more with a perfectly executed squeeze bunt.

The Trojans have outscored opponents 64-19 during their five-game NCAA tournament winning streak. And are one win away from advancing to the College World Series for the first time since 2001. Game 2 is set for 11 a.m. PDT Saturday on ESPN.
