Leiter didn't pitch as scheduled Thursday against the Tigers due to a back injury, Greg Joyce of the New York Post reports.

Leiter's injury doesn't seem to be anything too serious, but the Yankees are choosing to be cautious with the righty. He's slated to face hitters in a live batting practice session Sunday, and if all goes well he could return to playing in the Grapefruit League soon.

Manager Bruce Bochy said Saturday that Bradford (elbow) will be shut down from throwing for four weeks, Shawn McFarland of The Dallas Morning News reports.

Bochy's comments confirm that Bradford is not looking at a minimum-length stay on the injured list, as the left-hander will likely need significant time to build back up once his no-throw period is over. With Jon Gray (wrist) also slated to miss the beginning of the season, Jack Leiter and Kumar Rocker are both likely to join the Rangers' Opening Day rotation.

Fitts allowed one hit and struck out four over 4.1 scoreless innings in Friday's spring start against Miami.

After a couple of Grapefruit League appearances as a reliever, Fitts' last two appearances were as a starter. It's become apparent that Fitts will be part of the rotation to start the regular season, as several projected rotation members are expected to open the season on the injured list. The right-handed Fitts has a 0.84 ERA over 10.2 spring innings.

Paddack gave up two earned runs over four innings with six strikeouts and no walks in Friday's split-squad win over the Rays. He has a 5.59 ERA with nine strikeouts and no walks this spring.

Paddack left his previous start Saturday with a head contusion after a liner deflected off his glove, but he never entered the concussion protocol. He looked back to full strength and the injury doesn't look like an issue for Opening Day. While Paddack hasn't had the best numbers this spring, he's had decent strikeout totals and appears set to begin the season as the Twins' No. 4 starter.

Manager Alex Cora confirmed Saturday that Crochet will start Opening Day against the Rangers, Christopher Smith of MassLive.com reports.

After throwing 6.1 shutout innings in spring training, Crochet has officially earned the honor of starting on the bump Opening Day for his new team. His Red Sox debut will come against a Rangers squad that finished 11th in the American League with a .685 OPS last season but has brought that number up to .790 this spring.

Estevez (back) made his first appearance of spring training Friday, giving up one unearned run and two hits over an inning. "I feel great," Estevez told MLB.com. "Everything is going well with my body, and I'm in a good spot. For me, it usually takes me three, maybe four outings to say, 'OK, this is it, this is the point I want to be at.'"

Estevez has been slowed in camp by lower-back tightness, but the Royals say they are confident he'll be ready for Opening Day. He'll make six appearances between major-league and minor-league games barring any setbacks before spring training ends, according to MLB.com. Estevez is expected to be the primary closer for the Royals, with Lucas Erceg also getting some save chances.

Through four Grapefruit League appearances, Holton has allowed one run on two hits and two walks across 3.2 innings while striking out three.

The Tigers haven't used Holton heavily so far this spring after the lefty logged a career-high 94.1 innings during the regular season last year followed by 5.2 more innings in the postseason. Holton was effective in the regular season with a 2.19 ERA and 0.78 WHIP, and he was able to give the Tigers some length out of the bullpen when needed. The 28-year-old also recorded eight saves as a secondary option behind Jason Foley, who led the team with 28 saves. Foley is still likely the top closing candidate in Detroit heading into 2025, but both Holton and newcomer Tommy Kahnle figure to be in the mix as well.

Through five Grapefruit League appearances, Foley has allowed five runs on eight hits across 4.1 innings.

Foley was solid for the Tigers in 2024, posting a 3.15 ERA and 1.18 WHIP during the regular season and leading the team with 28 saves, so the righty should have a little leeway despite his spring struggles. He still looks like the top candidate for saves in Detroit to start the year, though newcomer Tommy Kahnle is expected to be in the mix along with holdover Tyler Holton, and possibly Will Vest and Beau Brieske as well. Foley will likely need a strong start to his season to solidify his grip on the closer role.

The Mariners optioned Klein to Triple-A Tacoma on Friday.

Acquired from the Athletics in January, Klein has allowed four runs (two earned) with an 8:3 K:BB over five innings during Cactus League play. He'll represent relief depth at Tacoma and should get an opportunity with the big club eventually.

Swanson has been diagnosed with a median nerve entrapment in his right forearm, Keegan Matheson of MLB.com reports.

Swanson has had recurring issues with his forearm/elbow and now there's an explanation as to what's going on. All things considered, the diagnosis could be worse, although it's not clear when he might be ready to pitch in games again. For now, Swanson will be shut down from throwing for at least a couple days. He is expected to begin the season on the 15-day injured list.
