Athletics' No. 1 prospect De Vries to undergo shoulder procedure, out for rest of season
Leo De Vries, the Athletics' top-ranked prospect, will have right shoulder surgery and miss the remainder of the minor-league season, with an expected recovery time of eight months. The 19-year-old, acquired from San Diego in the Mason Miller trade, had been sidelined since mid-August with a shoulder issue. He finished the 2026 season at Double-A with an .836 OPS, 13 home runs, and 21 doubles across 93 games.
The procedure was confirmed by an anonymous team source to Keith Law. De Vries has been sidelined since mid-August and was placed on the 60-day injured list. He is a 19-year-old shortstop expected to eventually shift to third base.
Acquired from San Diego in the Mason Miller trade, De Vries had a strong 2026 campaign at Double-A Midland before the injury. He also participated in the Futures Game, where he singled and stole two bases. His recovery timeline of eight months puts his return around mid-2027.
This injury could delay the Athletics' rebuilding timeline, as De Vries was a key piece acquired in the Mason Miller trade. His absence may impact the team's future infield plans, given his anticipated move to third base. For the player, an eight-month recovery could affect his development and ranking, though his high ceiling suggests he may still be a cornerstone. The broader impact is limited to the team's fanbase and prospect watchers, who may see a slight setback in the franchise's competitive window.
