Leo De Vries

Originally signed by San Diego for a record-setting bonus in the 2024 international class, Leo De Vries was the headline piece sent to the Athletics in the July 2025 deadline deal that moved Mason Miller and JP Sears. The switch-hitting shortstop carries a 65 overall grade built on a balanced sheet: a 60 hit tool, 55 power, 55 run, 55 arm, and a 50 glove, the look of an everyday up-the-middle regular with upside for more. He has answered every challenge in 2026, opening at Double-A Midland as a 19-year-old and hitting well above his age, with reports putting him around a .330 average with a near-.430 on-base mark and strong strike-zone control (a roughly even walk-to-strikeout ratio). A torrid spring (over .420 with three homers in Cactus League play) only added to the buzz. The questions are mostly about ceiling rather than floor: whether the power grows beyond average and whether he sticks at shortstop or slides to second or third as he fills out. De Vries projects to push toward Triple-A in short order, with a late-2026 or 2027 debut on the table given how advanced the approach already is at Double-A. For collectors, his 2024 Bowman Chrome is the cornerstone, capturing his first chrome rookie-year prospect cards with the refractor and autograph parallels that drive a top-five-overall name. The bull case is a 19-year-old switch-hitting shortstop already controlling the zone in Double-A, the exact profile that holds a card market through promotions and into a big-league debut, with the new-organization narrative in Oakland giving him a clear runway to play. The bear case is that the power settles at fringe-average and a position shift off shortstop softens the premium, or that the aggressive assignments eventually expose holes against upper-level pitching, scenarios that would reframe him as a solid regular rather than the star the market is betting on.
