Manager Aaron Boone said Saturday that Bellinger's back "went out on him a little bit," Meredith Marakovits of YES Network reports.

Boone added that Bellinger is expected to sit out the Yankees' next few Grapefruit League games before returning Tuesday, so it doesn't sound like an issue that will impact his Opening Day status. The 30-year-old outfielder is 4-for-9 with an RBI and a run scored through his first three exhibition matches.

Marte signed a one-year contract with the Royals on Saturday, Mark Feinsand of MLB.com reports.

Marte is coming off his most efficient season in three years, as he finished 2025 with a .270/.335/.410 slash line to go with nine homers, 34 RBI, 37 runs scored and seven steals in 329 plate appearances. That being said, the 37-year-old outfielder hasn't appeared in more than 100 games since 2022, and he likely isn't slated for a full-time role in Kansas City either. Instead, he'll presumably work in tandem with Jac Caglianone in right field and Carter Jensen at DH, filling in for one of the two against left-handed starters.

Arquette underwent core muscle surgery Friday, Christina De Nicola of MLB.com reports.

Arquette paused his offseason workouts after suffering a left groin injury. His discomfort returned after he restarted his activities during spring camp, so he went under the knife to address the issue. He'll require 4-to-6 weeks of rest before resuming baseball activities.

Crawford (shoulder) will take live at-bats Saturday, Daniel Kramer of MLB.com reports.

Crawford's shoulder has never been considered a threat to his Opening Day availability, as the Mariners previously said they're simply taking a cautious approach with ramping up the veteran infielder. He's expected to make his first Cactus League appearance of the spring Tuesday as a DH and begin playing in the field the following week.

Sproat allowed one earned run over 1.1 innings in Friday's spring game against the White Sox. He gave up three hits, struck out three batters and walked one.

Sproat made his first start since being acquired from the Mets and tossed 35 pitches while hitting 99.8 mph with his fastball, per Todd Rosiak of the Milwaukee Journal Sentinel. Sproat is in the mix for a spot at the back end of Milwaukee's rotation, though it may be a bit until roles are sorted out.

Miller received a platelet-rich plasma injection Saturday to treat inflammation in his left side, Shannon Drayer of SeattleSports.com reports.

Miller reported soreness after pitching in Thursday's Cactus League game against Cleveland, and an MRI later confirmed inflammation. He will now be shut down from throwing for five days, after which he'll begin playing light catch. A timeline for his return will emerge as he progresses in his throwing program.

Peralta struck out three over three perfect innings in Friday's Grapefruit League game against the Cardinals.

Making his first start of the spring, Peralta fired 18 of 29 pitches for strikes while fanning Jose Fermin, Nathan Church and Blaze Jordan. The 29-year-old right-hander had been named the Mets' Opening Day starter earlier in the day, and he heads into his first season in Queens having reached 200 strikeouts in each of the last three seasons for the Brewers, posting a 3.40 ERA and 1.14 WHIP during that time with a 10.7 K/9.

Williams is focused on adding a cutter and slider to his repertoire this season, Anthony DiComo of MLB.com reports.

The reliever known as the Airbender has been almost exclusively a fastball-changeup artist during his career, but a tough 2025 season with the Yankees in which he posted a career-worst 4.79 ERA, albeit with a much more palatable 2.68 FIP and 3.05 xERA, has Williams looking for an extra edge. The early results in spring training on the new pitches haven't exactly been encouraging -- Cardinals prospect JJ Wetherholt homered on a first-pitch cutter Friday -- but Williams isn't concerned. "That one specifically, I was just trying to throw a strike and he jumped on it," Williams said. "I kind of babied it, trying to just throw it over the plate. He wasn't giving me strike one." The 31-year-old right-hander is still going to lean heavily on his changeup to generate strikeouts, but having other options could help the Mets' new closer to rebound.

DeLauter (lower body) will resume running Saturday, Tim Stebbins of MLB.com reports.

DeLauter was a late scratch from Wednesday's contest with a lower-body injury, but after a few days of rest, he's been cleared to start up a running program. The Guardians are hopeful that he'll return to Cactus League action within the next few days, so his Opening Day availability doesn't seem to be in jeopardy.

Acuna went 2-for-3 with a walk, a grand slam, two additional runs scored and two stolen bases in Friday's Grapefruit League game against the Red Sox.

The star outfielder clubbed his first homer of the spring with the bases loaded in the third inning off minor leaguer Steven Brooks, one of four long balls by Atlanta on the day. Power display aside, it was Acuna's activity on the basepaths that might be the most important takeaway for fantasy GMs -- while the 28-year-old didn't run much last season after May 2024 surgery to repair a torn ACL, he's just a couple years removed from becoming the first player in MLB history to join the 40-70 club in 2023, stealing 73 bags in 87 attempts to go along with 41 homers, 106 RBI, 149 runs, a .337/.416/.596 slash line and NL MVP honors.
