The Dodgers suffered a deflating 9-3 loss to the Arizona Diamondbacks at Dodger Stadium on Friday to start their final series before the All-Star break.

But if there was a silver lining to the Dodgers rough performance, it was that superstar Shohei Ohtani looked fine at designated hitter after being scratched from his scheduled start because of irritation in his left knee.

Ohtani, will not participate in next week’s All-Star Game in Philadelphia, hit a leadoff home run off Diamondbacks starter Eduardo Rodriguez.

“I found out yesterday morning,” Roberts said of Ohtani’s injury. “So if there’s a chance that we could kind of be proactive and get it drained and do whatever we need to do to try to manage it, along with the rest for the All-Star break, we were gonna do that.

“But obviously the way he’s swinging the bat hasn’t really affected performance,” Roberts added. “We have certainly curtailed the stealing bases. But he feels good, obviously, and he’s gonna be DH’ing the next three games.”

The Diamondbacks took advantage of the Dodgers’ bullpen game — and three defensive errors.

Right-handed pitcher Kyle Hurt opened and surrendered two runs on three hits through 1⅔ innings.

Arizona’s Ketel Marte and Geraldo Perdomo opened the game with base hits. Corbin Carroll grounded into a force out at second, moving Marte to third, before Gabriel Moreno singled on a liner to right that scored Marte. Carroll then scored on an errant throw to third from Kyle Tucker that went into the Dodgers’ dugout.

After Ohtani hit his 21st homer of the season, Andy Pages hit a tying 419-foot blast to left-center for his 17th homer.

But that was all the Dodgers (61-34) would score against Rodriguez, who gave up seven hits and struck out five over six innings to improve to 8-3.

Arizona’s bullpen then held the Dodgers to just two hits — both coming in the ninth inning off Drey Jameson.

Will Klein (3-4) took the loss after surrendering one run through 1⅔ innings.

After Brock Stewart gave up a two-run home run to Tim Tawa in the fourth, Arizona (47-47) tacked on two more runs in the fifth after the Dodgers’ second error.

Stewart walked Perdomo to start the frame. Then, Carroll grounded into a fielder’s choice in front of the plate and reached first safely, with an errant throw by Rushing allowing Perdomo to reach third. Moreno grounded out to third to drive in Perdomo. A balk by Edgardo Henriquez followed by a wild pitch allowed Carroll to score.

Arizona extended its lead in the sixth after Tawa hit an RBI single to left and Perdomo drove in a run on a groundout to first. Tawa ended his four RBI performance with a run-scoring single in the eighth.

Reliever Alex Vesia threw a scoreless ninth inning for his fifth consecutive scoreless outing to cap a night the Dodgers probably would like to forget.

Will Smith crouched, his left knee on the ground and his mitt grazing the dirt as his Team USA teammate Mason Miller strode towards the plate.

From there, the only way for his glove to go was up and through the slider that fell out of the strike zone as the Dominican Republic’s Geraldo Perdomo stopped his swing. But, in a full count, home plate umpire Cory Blaser called it strike three.

Miller threw his hands above his head. Smith pumped his first. And the United States advanced to the World Baseball Classic final.

“That’s the work we do in the cage, and off the machine, and drills, and all that coming to fruition, and being applied to in-game,” Smith said in a recent conversation with The Times.

He has a slim chance of replicating that moment during the season, with the ABS challenge system implemented in MLB. If it had been in play during the WBC — as long as the Dominican Republic had challenges left — Perdomo surely would have used one on the final pitch of that 2-1 game.

And yet, as counterintuitive as it may sound, Smith dedicated time and effort during spring training to improving his framing.

“It’s important because you only get two challenges a game, offensively and defensively,” Smith said. “The whole team only gets those two. So the harder I can make it on the other team to challenge pitches, the better. The more strikes I can get and not have to challenge, the better. I think overall, it almost makes it more important, in a way.”

Framing had been a weakness in Smith’s game in recent seasons, according to Statcast’s catching metrics. His best season was 2023, when he recorded four runs saved via pitch framing. But he slipped to minus-eight and minus-10 the next two seasons. Entering the Dodgers’ series against the Phillies this weekend, he was at an even zero after 43 games at catcher this season, including 39 starts.

And now, when Smith doesn’t get a call, he has ABS to fall back on. Entering Friday, he’s challenged 41 calls through the ABS system from behind the plate, the 10th-most of any catcher. And he had a 71% success rate, the ninth-best mark among catchers with at least 20 challenges.

Because the catcher has the best vantage point, teams across the majors have made their catchers, not their pitchers, the point men for ABS challenges on defense.

ABS as a skill, however, isn’t just about getting the challenges right. Knowing the right times to take a risk is also key.

“There’s so many games within the game,” Smith said, “and that’s just another one of them.”

As Smith alluded to, under the challenge system — as opposed to fulltime ABS, which MLB also tested in the minors — it’s still possible to steal strikes.

“I like the challenge system because you still have the human error element to the game,” Smith said. “…Everyone always talks about how it’s a game of life, dealing with failure and dealing with ups and downs — the umpire screwing you or catching a break, that’s part of the game.”

Now, the players have recourse for the egregious calls and the biggest moments of the game.

The margins are so slim, however, that if a hitter isn’t convinced enough on a borderline strike call, and the situation dictates caution, he may not challenge.

The same goes for a catcher on a borderline ball call.

That’s where Smith’s work on framing comes in. He describes it as a change in philosophy.

“For me, it’s more just understanding the move,” Smith said. “I had to drill it in a little bit obviously, but more understanding the move of going farther out to get it, working through the ball, more like towards the pitcher, as opposed to letting the ball kind of come back to you. That was just not how I’d ever done it.”

That’s what he did on that last pitch of the WBC semifinals. Moving through the ball creates a more seamless motion, compared to pulling it into the strike zone, making the frame job more convincing. And catching it out in front also stops the ball’s own movement before it gets too far out of the zone.

That’s how Smith made a pitch that appeared to cross the plate below Perdomo’s knees look like a strike from Blaser’s vantage point.

The effect Smith’s spring training work behind the plate will have on the Dodgers’ season will be subtler. Instead of a singular game-defining moment, it’ll be an edge here and there.

But over the course of a long season, that adds up.
