Rangers top prospect Sebastian Walcott, one of the most touted prospects in the entire sport, could miss the entire 2026 season due to an elbow injury that will require surgery, president of baseball operations Chris Young announced to the team’s beat this morning (link via Jeff Wilson of DLLS Sports). Walcott could potentially get at-bats late in the season, and if he’s healthy, he’ll be a prime candidate to make up some lost reps in the Arizona Fall League and/or in winter ball. Young added that righty Nabil Crismatt, who’s in camp as a non-roster invitee, is also headed for elbow surgery (via Wilson).
Walcott appeared in last year’s Arizona Fall League, but his time there was cut short by elbow inflammation. Surgery was not recommended at the time. Evan Grant of the Dallas Morning News writes that Walcott spent the offseason rehabbing and felt strong entering camp, but he recently experienced renewed discomfort when throwing. A consultation with renowned surgeon Dr. Keith Meister revealed “structural changes. Walcott will have surgery to repair the ulnar collateral ligament in his elbow, it seems, but it has not yet been determined whether he’ll require a full Tommy John procedure (i.e. ligament reconstruction) or an internal brace procedure to repair/strengthen the existing ligament. The latter comes with a shorter timetable for recovery.
It’s a brutal blow to the Rangers and their farm. Walcott is only 19 years old (20 next month) but already appeared on the cusp of MLB readiness. The Bahamian-born shortstop spent the 2025 campaign in Double-A and hit .255/.355/.386 (110 wRC+) despite being the youngest player in the league.
In 552 plate appearances, Walcott hit 13 home runs, 19 doubles and two triples. He also went 32-for-42 in stolen base attempts, walked at a huge 12.7% clip and only struck out in 19.6% of his plate appearances. That’d be a productive season even for a more physically developed 23- or 24-year-old, but Walcott enjoyed that success in spite of being five years younger than the average Texas League player.
More to come.
