right-handed pitcher

CINCINNATI — A simple change opened up a dramatic offensive turnaround for Dodgers left fielder Teoscar Hernández.

Hernández’s two-run homer Tuesday, in the Dodgers’ 4-0 win against the Reds, was his second home run in as many nights, as the team trimmed its magic number to clinch the division to two. And, significantly, this one was against a right-handed pitcher.

“It’s been very helpful,” manager Dave Roberts said after the game. “As certain guys are not seeing the ball as well, it’s nice to kind of backfill with guys like Teo swinging the bat. And when you can slug like he can, you can win baseball games, and he can carry us for a while. And the last 10 days, something like that, it’s been really good from him.”

Through the end of August, Hernández had just a .668 OPS against right-handed pitchers this season. So, when manager Dave Roberts was asked in Detroit whether the Dodgers would consider setting up a left-field platoon with the team’s September call-ups, he said yes.

Hernández homered off Tigers left-hander Framber Valdez on the last day of the series. And before the Dodgers opened a three-game set against the Cardinals at Dodger Stadium, Hernández met with the hitting coaches.

Against Valdez, Hernández was in a closed stance, to delay his front hip from opening, according to Dodgers hitting coach Aaron Bates. But the team’s hitting group thought a return to a familiar setup could be a long-term solution.

“It was a great meeting we had,” Bates said. “We all talked about it, and then he felt comfortable enough to do it, and then the rest is to his credit. He’s just been who he is.”

In the past, Hernández had used a “twister tap” as his stride. He started in a more open stance, tapped his toe in line with the pitcher, and then set his foot down. But lower-body injuries the last couple of years — a left groin strain last season and a left hamstring strain earlier this season — forced him away from it.

His improved health and hip flexibility opened up the avenue for him to return to that timing mechanism.

“When Teo’s hips are loose that way, and his front leg looks like an Elvis knee, it’s a good sign for us,” Bates said. “Because that means that he can open and close it without his upper body going with it.”

The advantage of the twister tap, as Hernández explained it, is how repeatable it is. A more traditional stride can be sped up or slowed down.

“Just being able to control my body and being in a good position,” Hernández said earlier this month. “I can see the pitch a little sooner and identify what kind of pitch it is and if it’s going to be a strike or a ball.”

With that change, he’s rewarded the Dodgers for deciding against platooning left field. Hernández entered Tuesday with a .777 OPS against right-handed pitchers — a sample size of just 28 plate appearances but still a significant jump.

“The biggest thing is his plate coverage away,” Bates said. “Because now he can spoil pitches, and he’s staying in at-bats longer.”

Hernández’s dramatic offensive turnaround, along with fellow corner outfielder Kyle Tucker’s improvement, have helped steady a Dodgers offense that’s missing Shohei Ohtani (on the IL with right biceps and left knee injuries) and includes a hobbled Freddie Freeman (right knee soreness).

Rookie Josue De Paula, mostly filling in for Ohtani at designated hitter, has already shown he can take mature at-bats and provide some pop. But he’s still finding his footing in a new league.

It lengthens the Dodgers lineup for Hernández, after a slow start to his year, to return to being a veteran power threat — just in time to, ideally, carry the momentum into the postseason.

On Monday, he launched his two-run shot off left-hander Nick Lodolo. On Tuesday, he replicated the feat off right-hander Rhett Lowder.

On the second pitch of the at-bat, Hernández recognized a hung slider, and he roped it over the left-field fence at 109.3 mph, according to Statcast. The blast put the Dodgers up 3-0 in the third inning, with Dodgers starter Yoshinobu Yamamoto settling into a groove on the other side.

Yamamoto had walked the first two batters he faced, but he reigned in his control to pitch seven scoreless innings and allow just one more baserunner, on a double by Reds star shortstop Elly De La Cruz.

The Dodgers also scored on Hunter Feduccia’s second-inning single and Alex Freeland’s seventh-inning homer. And the Dodgers bullpen completed the shutout.

Freeman staying in the lineup

Freeman was all smiles after his three-hit game Tuesday — after going hitless for his last four games.

“I was supposed to be off tomorrow, but I played myself in there,” he said. “So I’m very excited.”

Roberts explained: “He was joking, saying, ‘If I get three hits, then can I be in there tomorrow?’”

Sure enough, the mechanical adjustments he made in the batting cage — focusing on getting his foot down early and making contact out in front — got him there.

“I’m just trying to find something that gives me results,” Freeman said. “We’re at the time where we’re just trying to get hot for five weeks here. So kind of like I did in the World Series a couple years ago, I did the step-out move. That’s not sustainable over six months. I’m not trying to find something that’s sustainable.”

Though Roberts has been trying to find opportunities to rest Freeman, he saw promising signs Tuesday beyond the results.

“Just my eyes, just watching him move, I feel good about him going tomorrow,” Roberts said.

De Paula, Freeland and third baseman Max Muncy will be out of the lineup Wednesday, Roberts said.
