Injury: Arm fatigue

Texas' top prospect has been sidelined in the Arizona Fall League with arm fatigue, according to MLB.com's Kennedi Landry. The organization plans to have Walcott rest and then will re-evaluate him in a few days. The 19-year-old has played in one game for Surprise -- he collected two hits, a walk and two runs in four at-bats after compiling a slash line of .255/.347/.427 with 13 homers, 71 runs and 59 RBIs for Double-A Frisco during the regular season.

TOP 100 PROSPECT NEWS
(ordered by ranking)
No. 12 Bryce Eldridge, 1B, Giants
Injury: Bone spur in left wrist
Expected return: 2026
The Giants announced that their top prospect will undergo surgery on Oct. 2 to remove a bone spur from his left wrist. He is expected to spend eight weeks rehabbing, which would leave him ample time to recover before the start of Spring Training. (Last updated: Oct. 1)
No. 17 Travis Bazzana, 2B, Guardians
Injury: Left oblique soreness
Expected return: 2026
The first overall pick in the 2024 Draft exited Thursday's game before the bottom of the fifth inning with left oblique soreness, a source tells MLB.com's Tim Stebbins. Bazzana made a leaping grab at second base in the fourth inning, and his spot in the lineup did not come up in the top of the fifth. The Australian native previously missed nearly two months on the injured list this summer because of an internal right oblique strain. (Last updated: Sept. 12)
No. 37 Bryce Rainer, SS, Tigers
Injury: Dislocated right shoulder
Expected return: 2026
Detroit's 2024 first-round pick will undergo season-ending surgery after dislocating his shoulder diving back to first base in a June 3 game for Single-A Lakeland. He slashed .288/.383/.448 with a 134 wRC+ in 35 games this season. Rainer is expected to be a full participant in Spring Training next year. (Last updated: June 6)
No. 40 Noah Schultz, LHP, White Sox
Injury: Knee discomfort
Expected return: TBD
It's a second stint on the injured list due to knee discomfort for the 6-foot-10 southpaw. Schultz missed nearly two months due to the ailment earlier this summer and made two starts (five innings) since returning. Across two levels this season, the White Sox 2022 first-rounder has battled his command (5.5 BB/9) while still showing off his premium swing-and-miss stuff (9.4 K/9). Schultz was already expected to pitch in the Arizona Fall League next month as a means for making up for lost innings. (Last updated: Sept. 4)
No. 44 Ryan Sloan, RHP, Mariners
Underwent season-ending eye procedure
The 19-year-old underwent an eye procedure that will only sideline him for 2-3 weeks, according to the Mariners. But given the timing, that will end Sloan's very strong first full pro season. The right-hander, the 55th overall pick in the 2024 Draft, reached High-A down the stretch after pitching to a 3.44 ERA and 77-15 K/BB in 18 starts at Single-A. (Last updated: Sept. 7)
No. 47 Owen Caissie, OF, Cubs
Injury: Concussion protocol
On the same day he was recalled from Triple-A Iowa, Caissie left the game at Wrigley Field after making a catch but hitting his head on the ivy-covered brick wall. Playing in right field for the Cubs in his first Major League game since Aug. 28, Caissie made a running catch in right-center field but lost his footing and fell forward, hitting his head.

No. 49 Travis Sykora, RHP, Nationals
Injury: Torn UCL
Expected return: Potentially late 2026
After an MRI unveiled a torn UCL, the right-hander will undergo UCL reconstruction in two weeks, the club announced. Sykora left his July 5 start after one inning due to lower right triceps soreness and has not pitched in a game since. The 21-year-old had been one of the Minors most dominant pitchers this season, registering a 1.79 ERA across 12 starts and reaching Double-A. (Last updated: July 28)
No. 58 Chase DeLauter, OF, Guardians
Called up to the Majors
DeLauter, who underwent hamate fracture excision surgery on July 23, made his Major League debut in Game 2 of the American League Wild Card Series. He becomes just the sixth player to debut during a postseason game. When healthy, the 2022 first-rounder slashed .278/.383/.476 and reached base in all 34 games for Triple-A Columbus during the regular season. (Last updated: Oct. 1)
No. 64 Mike Sirota, OF, Dodgers
Injury: Right knee
Expected return: 2026
Sirota has been sidelined since exiting High-A Great Lakes' July 5 game after an awkward slide in the sixth inning. The Loons placed him on the 7-day injured list and transferred him to the 60-day IL on July 13. Acquired in the Gavin Lux deal last winter, the 2024 third-rounder performed very well in his first season in the Dodgers' system, producing a .333/.452/.616 slash line with 13 home runs in 59 games across Single-A and High-A. (Last updated: July 29)
No. 65 Theo Gillen, OF, Rays
Injury: Left middle finger fracture
Expected return: 2026
After calf and oblique injuries sidelined him earlier this season, Tampa Bay's 2024 first-rounder has landed on the injured list again, this time with a broken middle finger on his left hand. When on the field, it's been a strong first foray into pro ball for Gillen, who led the Carolina League in on-base percentage (.433) by a considerable margin at the time of injury. A gifted runner, the 19-year-old has been successful on 36 of 39 stolen-base attempts and posted a 150 wRC+ in 73 games for Single-A Charleston. (Last updated: Aug. 15)
No. 77 Ethan Salas, C, Padres
Injury: Lower back stress reaction
Expected return: 2026
Back spasms threw a wrench into Salas' early-season plans, and he hasn’t appeared in game action since April 17. The Padres were optimistic his recovery would simply require rest and wouldn't impact his development much, aside from the missed games, initially projecting a late July return. But Salas' injury has been slow to heal, per reports, pushing back that timeline. (Last updated: Sept. 12)
No. 87 Jarlin Susana, RHP, Nationals
Injury: Right triceps soreness
Susana underwent successful surgery on his right lat muscle last week. The 21-year-old was diagnosed with right triceps soreness after he exited his Aug. 30 outing for Double-A Harrisburg in the second inning. Susana was shaking his right arm following a pitch, and left the mound in obvious discomfort. The 6-foot-6 hulrer sustained a Grade 1 UCL sprain in his pitching elbow in May but rehabbed the injury before returning to make eight starts this summer. He was up to 57 strikeouts across 30 1/3 innings since his return and had hit as high as 103 mph on ballpark radar guns on multiple occasions. (Last updated: Sept. 15)
