2025 End-Of-Season farm system rank: #15
Jeremy Mahy’s organization take from our 2025 End-Of-Season Farm System Rankings:
The Athletics plan to open the 2028 season in Las Vegas. Whether or not that team is a legitimate contender or not remains to be seen. @TheRealNaClown believes the core of the offense will be there with Nick Kurtz, JacobWilson, Tyler Soderstrom and Brent Rooker likely to be joined by superstar in the making Leo De Vries. The question is will they have the pieces on the pitching side?

2026 International Signing: Johenssy Colome, SS (Dominican Republic) – $4M. Not included in the Top 50 rankings below. Would be slotted in Tier 4, possibly even toward the end of Tier 3. He should show up in our next Athletics prospects update.

Editor note: Several players who are not listed in the ranks below may still have prospect eligibility in your dynasty leagues. We made the decision to not rank them as they’re so close to crossing the 130 AB/50 IP threshold and we wanted to include some other younger prospects. Otherwise, they are Top 50 players.

Colby Thomas, OF (120 AB)
Luis Morales, RHP (48.2 IP)
Elvis Alvarado, RHP (42.1 IP)

Prospects1500 Tiers:
Tier 1: Players with high expectations of both making the majors and playing at an All-Star level for a number of years
Tier 2: Players with an above-average expectation of making the majors and being a solid contributor
Tier 3: Players with an average expectation of making the majors and being a solid contributor
Tier 4: Players who have the potential to make the majors; possible sleeper candidates for sustained MLB success
Tier 5: Players of interest, worth keeping an eye on, who may make (or have made) the majors but provide minimal impact

Levels listed for each player are the highest levels player reached in 2025

Tier 1

1. Leo De Vries, SS, 19, Double-A
The Athletics are thrilled with the idea of their top prospect De Vries joining Nick Kurtz and Jacob Wilson in the near future. The 19-year old shortstop was acquired at the 2025 deadline as the key piece in the trade with San Diego for All-Star reliever Mason Miller. The young future star from the Dominican Republic finished the season at AA Midland, where in 21 games, he slashed to the tune of .281/.359/.551. Over three levels, the talented, switch hitter clubbed 15 homers while stealing 11 bases. The Las Vegas-bound Athletics may have hit the jackpot with the 6’1″ promising prospect. (@100percent3G)

Tier 2

2. Gage Jump, LHP, 22, Double-A
One of the brightest stars in this farm system is the organization’s second round pick out of LSU in 2024. Jump debuted last season and started 24 games across High-A and Double-A. The results were positive. 31 IP, 45 K, 2.32 ERA at A+ Lansing, and then 81.2 IP, 86 K, and 3.64 ERA at AA Midland. He was also named to the All-Star Futures Game. Posting a 1.10 WHIP and 10.5 K/9 in his first taste against mid-to-upper level minor league hitting is a good litmus taste for his continued success and ascension toward the big leagues. Expect to see Jump assigned to Midland to begin 2026, with a good chance the A’s want to see him at Triple-A Las Vegas at some point this season. (@Scotty_Ballgame)

3. Jamie Arnold, LHP, 21, College
Arnold is a deceptive left-hander who creates extreme angle from a very low 3/4 to near sidearm slot, making his mid-90s fastball play well above the radar gun with heavy run and late life. The slider is a legitimate bat-missing weapon in the mid-80s with big sweep and depth that consistently earns plus grades, and the changeup has emerged as a real third pitch with sharp tumble and growing consistency. The delivery features pace, extension, and crossbody action that adds deception, though fastball strike efficiency will be the separator between starting and relief long term. The ingredients are there for a rotation profile built on a plus fastball-slider foundation with enough changeup to neutralize right-handers. If the command continues to trend forward, Arnold projects as a mid-rotation arm capable of missing bats at a high clip. Prior to his draft year, there was some reliever risk, but he improved his command and now points to a sure fire starter. (@ShaunKernahan)

Tier 3

4. Henry Bolte, OF, 22, Triple-A
5. Braden Nett, RHP, 23, Double-A
6. Devin Taylor, OF, 22, Single-A
7. Tommy White, 3B, 22, Double-A
8. Wei-En Lin, LHP, 20, Double-A
9. Henry Baez, RHP, 23, Double-A

Bolte, the local kid out of Palo Alto, HS in 2022, reached Triple-A last season and put up some excellent numbers across AA/AAA. He has some pop (9 HR) but even greater wheels, swiping 44 bags on the year. Nett and Baez were part of the package the A’s received from San Diego in the Miller deal. They both spent all of 2025 at Double-A on both sides of the trade, will both get looks in Spring Training, and could find themselves in Las Vegas to start the season. Taylor could potentially have been a first round selection, but the A’s snagged him in the second round last year. He debuted at Single-A and tallied 51 total bases in 28 games. White spent his second professional season playing in High-A and Double-A, and then the A’s gave him a good look in Arizona, where he slashed .292/.395/.444 with 3 HR and 20 RBI in 18 games. “Tommy Tanks” should be back in Midland to begin 2026. The Taiwanese lefty Lin pitched across three levels (A/A+/AA) as a 19-year-old last year, and punched out 12.1 batters per nine innings to go along with a 3.72 ERA. He’s one of my Under 21 prospects to watch in 2026. (@Scotty_Ballgame)

Tier 4

10. Joshua Kuroda-Grauer, SS, 23, Double-A
11. Jack Perkins, RHP, 26, MLB
12. Gavin Turley, OF, 22, Single-A
13. Mason Barnett, RHP, 25, MLB
14. Steven Echavarria, RHP, 20, High-A
15. Kade Morris, RHP, 23, Triple-A
16. Junior Perez, OF, 24, Triple-A
17. Edgar Montero, SS, 19, Rookie (DSL)
18. Shotaro Morii, SS, 19, Rookie (ACL)

Kuroda-Grauer has shown excellent contact skills and the ability to hit the ball to all fields so far in his professional career. Turley had some of the best exit velocities at the 2025 draft combine. How much he hits will determine how that power plays in game. Barnett made his MLB debut last year but struggled, there is #4 upside with a bullpen role the more likely outcome for him. The A’s believed so much in Echavarria, drafted in the third round of 2023, that they went $2 million over slot value to sign him. There is a mid-rotation pitch here if his changeup continues to develop. Morris features an arsenal that could make him a valuable innings eating starter with the occasional high strikeout outing. He could see the big leagues this year. Perez absolutely blew up in Vegas last year sporting 1.054 OPS in 151 AB’s. Vegas is a very friendly hitting environment, and he has run a high K-rate for his career so temper your expectations. Montero and Morii both bring some very intriguing skills to the table but are also very young. Montero demonstrated advanced strike-zone control and solid contact skills in his DSL debut. Morii has two-way player intrigue, it will be fun to see how the organization develops him as he goes through the system.

Tier 5

19. Gunnar Hoglund, RHP, 26, MLB
20. Eduarniel Núñez, RHP, 26, MLB
21. Ryan Lasko, OF, 23, Triple-A
22. Rodney Green Jr., OF, 22, High-A
23. Nate Nankil, OF, 23, Double-A
24. Cole Miller, RHP, 20, Single-A
25. Chen Zhong-Ao Zhuang, RHP, 25, Double-A
26. Tzu-Chen Sha, RHP, 22, High-A
27. Zane Taylor, RHP, 23, Triple-A
28. Will Johnston, LHP, 25, Triple-A
29. Clark Elliott, OF, 25, Double-A
30. Kenya Huggins, RHP, 23, High-A
31. Breyson Guedez, OF, 18, Rookie (DSL)
32. Myles Naylor, 3B/SS, 20, Single-A
33. Carlos Pacheco, OF, 21, High-A
34. Ayden Johnson, 3B, 17, Rookie (DSL)
35. Cooper Bowman, 2B/OF, 26, Triple-A
36. Brennan Milone, 1B/OF, 24, Triple-A
37. Jared Dickey, OF, 23, Double-A
38. Darwing Ozuna, OF, 17, Rookie (DSL)
39. Bobby Boser, SS, 23, Single-A
40. Pedro Pineda, OF, 22, High-A
41. Justin Riemer, 2B/3B, 23, Double-A
42. Logan Sauve, C, 22, College
43. Jose Ramos, OF, 19, Rookie (DSL)
44. Yunior Tur, RHP, 26, Triple-A
45. Cameron Leary, OF, 24, High-A
46. Sam Stuhr, RHP, 23, Single-A
47. Dylan Fien, C, 20, Single-A
48. Corey Avant, RHP, 24, Double-A
49. Euribiel Angeles, 2B/SS, 23, Triple-A
50. Jared Sprague-Lott, 2B/3B, 24, Single-A

Hoglund and Nunez have both made their MLB debuts and look to be competing for bullpen roles in the Spring. Bowman is that utility guy that you love to have on your team, he just grinds it out and brings high energy to the clubhouse. Green Jr. is a typical high-risk, high-reward prospect, the power/speed potential is sky high but his ability to make consistent contact is lacking currently. Sha’s arsenal consists of just average offerings but potentially elite control gives him a fairly safe floor. Taylor, drafted in the fifth-round last year, will not blow you away with his stuff but he too commands his arsenal at an elite level and could move through the system quickly. Milone brings average tools across the table and profiles as a fourth outfielder/bench player, one that could produce a solid OBP. The A’s Jose Ramos looked much better in his repeat of DSL ball, showing significantly more pop in his bat while also improving his contact rate. Tur pitched across three levels last season and has an outside chance to push for a roster spot in the Spring.
