A's Top Prospect Leo De Vries Set for Right Shoulder Surgery

The 19-year-old's expected eight-month recovery will rule him out for the rest of 2026 and push back plans for his major-league debut.

Overview

  • De Vries is scheduled to have an anterior labrum repair on his right shoulder on Sept. 13 and team reports put his recovery at about eight months.
  • An eight-month timeline effectively eliminates any chance he plays in MLB this year and would likely delay his arrival into the 2027 season, with return projections near May.
  • The switch-hitting shortstop/third baseman hit .290/.378/.458 with 13 home runs at Double-A Midland in 2026 and ranks among baseball's top prospects in multiple outlets.
  • The A's placed De Vries on Midland's injured list after he last played on Aug. 14 and moved him to the 60-day injured list on Sept. 1 as the shoulder issue persisted.
  • The injury adds to a string of recent setbacks for Oakland's system and raises priority on winter infield help while the club monitors a separate, developing incident in which pitching prospect Jamie Arnold was taken to a hospital after being struck by a line drive.
