Mason Miller deal still reshaping A's Top 30 as Leo De Vries sits at No. 1 and could debut

The trade that sent mason miller to San Diego continues to define the Athletics' prospect picture after a newly released Top 30 list ranks Leo De Vries No. 1 in the organization. De Vries' standing and a manager's open acknowledgement that he could reach the majors this year make the list a focal point for how the A's will populate Lansing and higher levels in 2026.

Mason Miller deal: how the trade reshaped the A's Top 30

The deadline trade that brought Mason Miller to San Diego also delivered a significant prospect package that now anchors the Athletics' draft-and-development ladder. The package was headlined by Leo De Vries, who emerges as the organization's top-ranked prospect on the March Top 30 compilation, and several upper-level arms who were slotted above Lansing on the prospect ladder.

Within the Top 30 release, 15 players on the list were noted as having come through Lansing, and multiple names acquired in the trade were identified as upper-level pitching pieces likely to open the year at Double-A Midland or higher. The reshuffling created by the trade has immediate roster and developmental implications for Lansing and the higher minor-league levels.

Leo De Vries' climb and the prospect list

Leo De Vries is listed as the No. 1 prospect in the Athletics' system on the Top 30 list. The compilation highlighted recent performances that tracked his jump through the minors: an April cycle in Lansing while with the Fort Wayne TinCaps, a hot stretch that included seven hits over three days in Dayton, and a promotion to Double-A to finish the season.

Those on the list who passed through Lansing include De Vries, Gage Jump, Wei-En Lin, Henry Bolte, Tommy White, Joshua Kuroda-Grauer, Kade Morris, Steven Echavarria, Gunnar Hoglund, Junior Perez, Ryan Lasko, Kenya Huggins, Nate Nankil, Chen Zhong-Ao Zhuang and Cameron Leary. The concentration of talent tied to Lansing underscores how the trade and subsequent promotions are affecting the composition of single-A and Double-A rosters heading into the new season.

Manager comments and the near-term outlook

Athletics manager Mark Kotsay said he won't rule out De Vries making the big-league club this year and noted being impressed with the player's spring training actions. Kotsay's assessment opens the possibility that De Vries could join a short list of prospects expected to make their Major League debuts this summer.

The Top 30 commentary called out a reasonable expectation that Gage Jump, Henry Bolte, Kade Morris and Junior Perez could reach the majors sometime this summer. It also suggested certain players—Wei-En Lin, Steven Echavarria, Kenya Huggins and Cameron Leary—might return to Lansing to open the season, while others acquired in the Miller trade are projected to begin the year at higher levels.

What the list means for Lansing and beyond

The concentration of prospects tied to Lansing means that both the Lugnuts' opening-day roster and midseason call-ups will be watched closely. The Top 30 notes several players who could provide immediate impact at Lansing, including outfielders and pitchers expected to slot into starting roles. Meanwhile, upper-level arms from the trade package are viewed as candidates for Double-A Midland or higher assignments, altering depth charts across the system.

Looking ahead

The Top 30 snapshot frames a season of potential transitions: a high-profile prospect at the top of the list with a manager publicly leaving the door open for a major-league debut, multiple Lansing-connected names poised to contribute at lower levels, and pitchers from the trade expected to accelerate through Double-A or beyond. The trade that centered on Mason Miller reshaped both immediate roster planning and the developmental blueprint for the organization.

Recent updates point to active roster movement and promotion possibilities; details may continue to evolve as spring training progresses and organizational decisions are finalized.
