Top 100 prospects: Injuries & roster moves
Here is the latest on injuries and roster moves involving MLB Pipeline's Top 100 prospects:
LATEST NEWS
No. 23 Aidan Miller, SS, Phillies
Injury: Back discomfort
Expected return: Day-to-day
Miller has been held out of baseball activities since Feb. 21 while dealing with recurring back soreness. The issue first flared up last year for the 2023 first-rounder, who missed the final few games of the 2025 Minor League season and was pulled from participating in the Arizona Fall League due to similar discomfort. The Phillies had planned for their top prospect to spend time at both shortstop and third base throughout the spring before his back pain returned. The club doesn't have a timetable for when Miller will resume baseball activities, but they are leaving the door open for him to still suit up in games this spring. If he doesn't play before the big league club breaks camp, Miller will likely return at some point during the season for Triple-A Lehigh Valley. The Florida native posted an .825 OPS across Double-A and Triple-A last season. More >> (Last updated: Feb. 28)
No. 47 Aiva Arquette, SS, Marlins
Injury: Underwent core muscle surgery
Expected return: 4-6 weeks
Miami's 2025 first-rounder sustained a left groin injury during offseason workouts in his native Hawaii and stopped baseball activities with hopes of recovering soon after. When he arrived at Spring Training and restarted his workouts, the pain returned, leading to core muscle surgery to remedy the discomfort. Arquette slashed .242/.350/.323 over 27 contests last season at High-A Beloit. More >> (Last updated: Feb. 28)

(ordered by ranking)
No. 7 Sebastian Walcott, SS/3B, Rangers
Injury: Underwent internal brace surgery on right elbow
Expected return: As early as August
It’s good news that the 19-year-old infielder avoided Tommy John surgery, shortening the recovery time. It’s going to be a timeline of about five to six months before he starts hitting, and the fielding will follow. Position players have a shorter rehab timeline for elbow surgery than pitchers with either the internal brace or Tommy John surgery. If Walcott returns in August, it’s conceivable that he could appear in regular-season games at a Minor League affiliate before heading to the Arizona Fall League or a Winter League in the offseason.

No. 8 Samuel Basallo, C/1B, Orioles
Injury: Side discomfort
Expected return: Day to day
Basallo exited a Grapefruit League game with right side abdominal discomfort in the third inning on Feb. 26, a move Baltimore manager Craig Albernaz later described as “precautionary.” The 21-year-old departed after laying on the ground and holding his right side, though he eventually walked off the field -- and back to the clubhouse. Albernaz said he doesn't expect Basallo to go for further testing. (Last updated: Feb. 26)

No. 46 Chase DeLauter, OF, Guardians
Injury: Lower body soreness
Expected return: Day to day
DeLauter was scratched shortly before first pitch on Feb. 25 in a precautionary move by the Guardians. The club made it clear all offseason that it would be mindful about DeLauter’s workload this spring given his physical history. He’s played just 138 games in the Minors since his selection in the first round of the 2022 MLB Draft. He was limited to 42 games last year, when he underwent core muscle surgery in March and right wrist surgery for a hamate fracture in July. (Last updated: Feb. 26)
No. 54 Travis Sykora, RHP, Nationals
Injury: Torn UCL
Expected return: Potentially late 2026
After an MRI unveiled a torn UCL, the right-hander underwent UCL reconstruction last August. The 21-year-old had been one of the Minor Leagues' most dominant pitchers last season, registering a 1.79 ERA across 12 starts while reaching Double-A. (Last updated: Feb. 26)
