Double-A Midland placed De Vries on its 7-day injured list Tuesday while he recovers from a sore right shoulder, Martin Gallegos of MLB.com reports.
The Athletics sent De Vries to their facility in Arizona to conduct his rehab and have shut him from throwing for four weeks, effectively bringing an end to his season. One of the top prospects in all of baseball, De Vries has spent his entire age-19 season at Midland, slashing .287/.376/.453 with 13 home runs and 34 stolen bases over 431 plate appearances. Assuming DeVries is ready to start throwing without issue by the end of September, he could pick up some additional at-bats in fall instructionals and/or the Arizona Fall League. The switch-hitting infielder doesn't have much left to prove in the minors, so he should be ready to make his MLB debut for the Athletics early in the 2027 season.
