The 22-year-old has made three rehab appearances in total, upping his pitch count each time out. He is set to make one final rehab start for Triple-A Buffalo on April 21.

No. 95 Gavin Fien, INF, Nationals
Injury: Left wrist inflammation
Expected return: TBD
Fien played in four games to open the year for Single-A Fredericksburg before left wrist inflammation shut him down.

No. 100 River Ryan, RHP, Dodgers
Injury: Hamstring
Expected return: TBD
Ryan was placed on the 7-day injured list on April 17 due to a hamstring issue. Injuries have sidetracked the 27-year-old throughout his pro career, most recently when Tommy John surgery knocked him out for the entirety of the 2025 season. Ryan has 10 strikeouts through seven innings across two starts this year for Triple-A Oklahoma City. (Last updated: April 17)
No. 19 Ethan Holliday, SS, Rockies
Injury: Left groin tightness
Expected return: Day-to-day
Holliday was lifted from Single-A Fresno's contest on April 11 due to left groin tightness a source told MLB.com's Jonathan Mayo and he has been held out of the lineup since. The fourth overall pick in the 2025 Draft got off to a slow start across his first three contests of the year, but went 6-for-19 with three walks and four RBIs over the next five outings.

(ordered by ranking)
No. 6 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. 18 Aidan Miller, SS, Phillies
Injury: Back discomfort
Expected return: Day-to-day
Phillies president of baseball operations Dave Dombrowski said on April 9 that Miller is back to swinging a bat after recurring back soreness prevented the club's top prospect from participating in baseball activities since Feb. 21. 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 club doesn't have a timetable Miller's return, in part because of the nature of back injuries and the recurring nature of his. Dombrowski is happy with his progress and does not see a reason to rush him; Miller will return to Triple-A Lehigh Valley when he is fully healthy. More » (Last updated: April 9)
No. 35 Josue Briceño, C/1B, Tigers
Injury: Right wrist surgery
Expected return: Summer 2026
Briceño said he expects to miss “a few months” after undergoing surgery to repair the extensor carpi ulnaris subsheath in his right wrist. The 21-year-old said he suffered the injury on a swing in his last Spring Training game on Feb. 28. Briceño made an impression in camp, including a home run off a Tarik Skubal slider during live batting practice in February. He batted 2-for-12 with a double and two RBIs in six Grapefruit League games. (Last updated: March 6)
No. 42 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)
No. 45 Edward Florentino, OF/1B, Pirates
Injury: Left ankle
Expected return: TBD
Out with a left ankle injury since February, Florentino has resumed baseball activities but is still expected to be out into April. The 19-year-old put together a tremendous 2025 campaign -- his first affiliate action -- slashing .290/.400/.548 with 41 extra-base hits, 16 homers, 59 RBIs and 35 stolen bases in 83 games across two Minor League levels.

No. 49 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)
No. 52 Jaxon Wiggins, RHP, Cubs
Injury: Right elbow inflammation
Expected return: TBD
Cubs manager Craig Counsell noted on April 15 that Wiggins was dealing with right elbow inflammation after not making his scheduled start on April 10. The 24-year-old was placed on the Minor League injured list due to lingering soreness, which the Cubs are hoping is just a minor issue. Wiggins last pitched on April 4 for Triple-A Iowa, and he had made only two starts this season prior to the move to the IL. He posted a 5.63 ERA over eight innings, striking out 10 and walking five.

No. 72 Jarlin Susana, RHP, Nationals
Injury: lat surgery
Expected return: TBD
Susana underwent lat surgery the week of Sept. 8. The 22-year-old had been limited to 56 1/3 innings in 2025 due to a Grade 1 UCL sprain in his elbow he suffered on May 4, then a right lat injury suffered on Aug. 30, which ended his season. Susana was a non-roster invite to Nationals big league camp this spring, but he did not compete in Grapefruit League action. (Last updated: March 25)
