Leo De Vries Headlines A’s 31 Non-Roster Invites to 2026 Spring Training

The Oakland Athletics announced 31 non-roster invitees to Spring Training, expanding their initial camp to 71 players and bringing a mix of elite prospects and experienced major leaguers into early competition. The group is headlined by infielder Leo De Vries, a young center of attention after his acquisition in the Mason Miller trade.

De Vries enters camp as one of the A’s most prized assets, appearing on MLB Pipeline’s Top 100 Prospect List at No. 4. He made his Double-A debut at Midland at age 19 and hit a combined .255 with 28 doubles, eight triples, 15 home runs, 74 RBI, 11 stolen bases and an .806 OPS in 118 games across Midland and Single-A stops at Fort Wayne and Lansing. Left-handers Jamie Arnold and Gage Jump also headline the non-roster class, carrying MLB Pipeline rankings of No. 41 and No. 57 respectively. The A’s materials separately presented a numbered list of top prospects not on the 40-man roster that lists De Vries as No. 1, Arnold No. 2 and Jump No. 3.

Camp composition reflects internal depth and outside acquisition. Eighteen of the invitees finished 2025 in the A’s organization, while 13 were signed to minor-league deals after the season. Sactown Sports noted that 14 of the non-roster invitees have Major League experience, including pitchers Nick Anderson, Wander Suero, Ben Bowden, Matt Krook, Geoff Hartlieb, Nick Hernandez, Brooks Kriske, Joel Kuhnel and position players Joey Meneses, Bryan Lavastida, Cade Marlowe, Brian Serven, Michael Stefanic and Chad Wallach. That veteran contingent provides immediate depth and a test bed for reclamation projects and depth pieces for Oakland.

Prospect and performance context gives fans clear storylines to follow. Outfielder Henry Bolte earned A’s Organizational Hitter of the Year honors after hitting .284 and stealing 44 bases between Midland and Triple-A Las Vegas. Third baseman Tommy White hit .275 in 93 games with Lansing and Midland. Infielder Joshua Kuroda‑Grauer led the A’s farm system with 147 hits. Outfielder Ryan Lasko recorded nine outfield assists in 89 games across three teams. Other noted numbers include McGuire’s combined .268 average and .392 on-base percentage with Midland and Las Vegas, and an entry listing “Elliot” at .251 with a .395 on-base percentage with Lansing and Midland.

Several invitees arrived via recent trades or international signings: Euribiel Angeles was acquired in the Sean Manaea trade, Kenya Huggins came in the Miguel Andujar deal, Kade Morris was acquired for Paul Blackburn, and Wei-En Lin was signed out of Taiwan at age 18. Those moves underline the A’s strategy of blending high-upside youth, international scouting and veteran reclamation.

For Triple-A and prospect followers, spring camp will accelerate evaluations. Early at-bats and bullpen sessions will shape assignment decisions, spot-starter depth and potential early-season call-ups. De Vries is the marquee name to watch, but the camp’s mix of proven MLB arms and high-contact, high-volume minor-league producers suggests Oakland will have multiple roster puzzles to solve before Opening Day.
