The Dodgers have yet to make any trades ahead of next Tuesday’s deadline.

But their roster got another notable shake-up Wednesday.

Before their game against the San Francisco Giants, the Dodgers activated pitcher Tyler Glasnow from the injured list, and signed and activated veteran shortstop Nick Ahmed.

In corresponding moves, shortstop Miguel Rojas was placed on the injured list with a flexor strain in his throwing arm. Pitcher Kyle Hurt was optioned, sent back to triple-A Oklahoma City despite his 3.07 ERA in nine outings this year. Reliever Ricky Vanasco was also designated for assignment to create room on the club’s 40-man roster for Ahmed.

Glasnow’s return was long expected, with the team’s right-handed ace returning as scheduled from back tightness he sustained before the All-Star break.

Rojas’ placement on the injured list was also no surprise, after he was removed early from Sunday’s game with discomfort in his forearm.

While the team was initially optimistic that Rojas could avoid an IL stint, manager Dave Roberts said a medical scan this week showed the strain in Rojas’ arm. His timeline to return is unclear, but Roberts didn’t make the injury sound serious.

“I think it’s something that he’ll be able to bounce back from,” Roberts said.

In Rojas’ absence, the Dodgers signed Ahmed to a major-league deal Wednesday, inking the 11-year veteran and two-time Gold Glover two weeks after he was released by the Giants.

Roberts said Ahmed, a longtime member of the Arizona Diamondbacks who batted .232 in 52 games with the Giants this year, would serve as the Dodgers’ primary shortstop in Rojas’ absence — or, at least, until Mookie Betts returns in the next couple of weeks from his broken hand.

“Got a call late last night, and came to terms pretty quickly,” Ahmed said of signing with the Dodgers. “Pretty obvious choice, just playing against these guys for a long time. Having the opportunity to compete and win a championship is something I want.”

The odd man out in Wednesday’s flurry of moves was Knack, the rookie right-hander who seemed to be establishing himself in the Dodgers rotation after a five-inning, one-run start Tuesday night.

Knack, however, became the casualty of a roster crunch. He had minor-league options. He was also the most recent member of the Dodgers rotation to pitch — which, with a couple off-days on the schedule in the next week, left his next potential start date unclear.

Instead, the Dodgers decided to send Knack down and preserve their bullpen depth, something that could be important the next two nights as Glasnow and Clayton Kershaw make their first starts back from the injured list.

“It was one of those timing situations for Landon,” Roberts said. “But I can’t say enough about what he did for our ball club.”

Buehler’s next steps

Walker Buehler said he will begin a rehab assignment with triple-A Oklahoma City on Friday. It will be his first live game action since going on the injured list last month with a hip injury.

Buehler is expected to make two rehab starts, Roberts said, before rejoining the Dodgers rotation next month.

Before going on the IL, Buehler had struggled in his return from a second Tommy John surgery, going 1-4 with a 5.84 ERA in eight starts.

Hurt having Tommy John

In other injury news Wednesday, the team announced that prospect Kyle Hurt is scheduled to undergo Tommy John surgery next week, ending his 2024 campaign and probably sidelining him for most of 2025 as well.

A USC product acquired in a 2021 trade with the Miami Marlins, Hurt had emerged as one of the top pitchers in the Dodgers’ farm system, earning the club’s minor league pitcher of the year award last year while leading all minor-league pitchers with 14.9 strikeouts per nine innings.

Hurt made his MLB debut with one outing last September, then opened this season in the Dodgers’ bullpen, giving up two runs (one earned) in 6 2/3 innings over three appearances.

He missed a couple of months earlier this year with a shoulder injury, but had been back pitching for Oklahoma City for a month before exiting an outing on July 4 with an apparent arm injury.
