The Athletics are promoting top prospect Leo De Vries to Double-A Midland after the switch-hitting shortstop’s recent hot stretch with High-A Lansing, MLB.com’s Martín Gallegos reported Sunday, citing a source.
De Vries is the league’s No. 3 overall prospect and was the A’s critical return piece in the deal that sent All-Star closer Mason Miller to the San Diego Padres at the 2025 MLB trade deadline.

At 18 years old, De Vries slashed .249/.354/.426 with 91 hits, 58 RBI and 10 home runs over 97 games between the Padres’ High-A Fort Wayne affiliate and the Athletics’ High-A Lansing team in 2025. He began his professional career with the Padres organization at just 17 years old in 2024, playing 93 games between Single-A Lake Elsinore and the Arizona Fall League’s Peoria.
De Vries will be the youngest player at the Double-A level when he debuts for the RockHounds, according to Baseball America, and will be the 19th player to reach Double-A at 18 years old since 2010.
A’s general manager David Forst told Chris Townsend about his expectations for De Vries on “A’s Cast” on Wednesday — and it was quite the foreshadowing.

“I think Leo De Vries has a chance to be a superstar,” Forst said, adding that “there is a learning curve no matter where you are, but I’d like to think he gets his feet wet in Double-A before the end of the year, starts there next year, and then he’s off and running.”
The A’s have liked what they have seen from De Vries and look forward to seeing him — the equivalent of a high school senior — get his feet wet at yet another big-boy level.
