The Oakland Athletics’ farm system received a notable upgrade in the latest 2025 rankings, driven in part by the Mason Miller trade. On August 11, 2025, MLB Pipeline released updated Top 30 prospect lists for all teams, and Oakland introduced three new players among the overall Top 100 prospects, including the highly regarded Leo De Vries, along with 2025 first-round draft pick Jamie Arnold and 2024 left-handed draftee Gage Jump. This update reflects the team’s strengthened pipeline as they prepare for the future.
Details on Top Prospects and Draft Picks Elevating the Ranks
Before the update, right-hander Luis Morales, who recently made his MLB debut, was among the A’s Top 100 prospects. However, he has dropped just outside the Top 100 but remains close to breaking back into that group. The core of the Oakland farm system remains stable, with several 2025 draft picks moving up in the rankings.
One standout newcomer is second-round draft pick Devin Taylor, who ranks eighth overall in Oakland’s farm system. Taylor has shown promising offensive abilities during his six games with the Low-A Stockton Ports, batting .333 with an impressive 1.148 OPS and two home runs. His progress has drawn comparisons to established prospects Jacob Wilson and Nick Kurtz due to his advanced hitting skills and ability to advance quickly through the minors.
The fourth-round selection, Gavin Turley, is positioned 14th in the system and has registered a .731 OPS with three extra-base hits in Stockton. Meanwhile, the fifth-rounder, Zane Taylor, debuted as the 29th-ranked prospect, currently gaining experience in the Complex League in Arizona.
Noteworthy Surprises and Stalwarts in Oakland’s Prospect Pool
One surprising inclusion is 11th-round draftee Bobby Boser, who claimed the 30th spot in the farm system rankings. His production in Stockton includes a .797 OPS with four extra-base hits, signaling a promising start for the late-round pick.
Additionally, the prospects acquired in the midseason trade involving Mason Miller and JP Sears remain firmly placed in the rankings. Leo De Vries leads the pack as the A’s number one prospect and ranks third overall in MLB‘s Top 100. Other players from the deal include Braden Nett (sixth in Oakland’s system), Henry Baez (tenth), Eduarniel Núñez (eighteenth), and Kenya Huggins (twenty-fifth). Huggins was also part of the trade linked to Miguel Andujar with the Cincinnati Reds.
International Signings Add Depth and Versatility
The A’s international recruitment continues to show promise with two-way player Shotaro Morii ranked 24th in the system. Morii, an 18-year-old from Japan, has excelled in rookie ball with a .783 OPS and 12 extra-base hits. His remarkable plate discipline features a 19.1% walk rate alongside a 25% strikeout rate. The organization plans for him to develop his pitching this offseason in the complex league, enhancing his status as a coveted prospect.
Shortstop Edgar Montero, another international signee who joined the Athletics for $1.2 million in 2024, has also joined the Top 30. In the Dominican Summer League, Montero is hitting .322 with a 1.119 OPS and has tallied 23 extra-base hits. His excellent plate discipline is reflected in a 26.9% walk rate paired with a 21.2% strikeout rate, marking him as a disciplined and patient hitter.
A Deep Pool of Talent Foreshadows a Bright Future for the Athletics
The remainder of Oakland’s Top 30 prospects maintains a strong group of familiar names, underscoring a farm system that may be the deepest it has been for decades. Beyond the Top 30, there are at least a dozen additional prospects who narrowly missed the cut but highlight the organization’s overall strength and future potential. This depth will be essential as the Athletics work toward returning to competitiveness at the Major League level with Mason Miller and other promising players leading the way.
