Updated A's Top 30 Prospects After Draft, Mason Miller Trade

Finally, and maybe the biggest surprise, the A's 11th-round pick from this past draft, Bobby Boser, ranks 30th overall in the farm. Boser has a .797 OPS with Stockton and four extra-base hits.

All the prospects the A's received at the trade deadline remain ranked: De Vries (A's No. 1, MLB No. 3), Braden Nett (A's No. 6), Henry Baez (A's No. 10), Eduarniel Núñez (A's No. 18), and Kenya Huggins (A's No. 25). Huggins was the player acquired in the Miguel Andujar trade with the Cincinnati Reds.

The A's biggest international free agent signing from last winter, two-way player Shotaro Morii, ranks 24th in the system. Morii has been hitting well in rookie ball, holding a .783 OPS with 12 extra-base hits.

The 18-year-old Japanese standout has shown impressive plate discipline, with a 19.1% walk rate and a 25% strikeout rate. Morii could start working on the mound this winter in the complex league, which will make him an even more coveted prospect.

Another international signing debuted in the A's Top 30. Shortstop Edgar Montero, who signed with the A's for $1.2 million in 2024, has had a good year. In the Dominican Summer League, Montero is hitting .322 with a 1.119 OPS and 23 extra-base hits. However, the most impressive stat is his 26.9% walk rate and his 21.2% strikeout rate.

The rest of the A's Top 30 is filled with familiar faces, and they come with a lot of potential. This farm system may be the deepest the A's have had in decades, and it extends far past the Top 30. There are at least a dozen additional prospects who could have made the list, which highlights the strength of the system.
