This list is for non debuted prospects only. I want all fresh faces, and I want everyone being evaluated on an even playing field with no MLB sample tainting the analysis. As usual, I go over 300 deep with blurbs for every player. Top 25 free here on the Brick Wall. Previous Rankings (Off-season and May) are in parenthesis. Here is the Top 300+ June 2025 Dynasty Baseball Prospects Rankings:

1) (21) (35) Konnor Griffin – PIT, OF, 19.1 – Roman Anthony finally got the call, and how fun is it to finally crown a new #1 non debuted prospect in baseball. And there is no funner (yes, I know that isn’t a word) prospect than Konnor Griffin. There is also no prospect with higher upside than Griffin. I was high on Griffin this off-season, but the Baseball Gods were telling me I wasn’t even high enough, writing in his FYPD Tier One Target blurb, “If one player in this group kinda pings my gut and heart every time I pass his name in the rankings, it’s Griffin. It’s like I’m getting a signal that he is the guy to truly go after. All of the college bats are good, but not great, and Griffin has the potential to be great. If you have the guts that I didn’t have in these rankings, maybe it’s Griffin that is the true top pick after Sasaki. Especially in a shallow league, it could be fun to roll the dice on him.” … and that dice roll is coming up 7’s if you took him first (I was able to nab him 11th overall in my 18 teamer). He conquered Single-A with 9 homers, 26 steals and a 156 wRC+ in 50 games, and his only weakness, plate skills, was improving massively by the end of his stint there with a 12.5/12.5 K%/BB% in his last 16 games. It earned him the challenge of High-A, and it’s gonna be fun seeing what he can do. He’s my #1 non debuted prospect in baseball.
2) (4) (15) Sebastian Walcott – TEX, SS, 19.3 – The game power is coming with 8 homers in 53 games at Double-A, and the plate skills are actually improving at the tougher level with a 21.2/12.4 K%/BB%. He’s not dominating, but he’s doing everything you wanted to see him do this year. I wouldn’t argue with you if you wanted to put Walcott first.
3) (7) (18) Josue De Paula – LAD, OF, 20.0 – I’ve been all in on Josue since he was a complete unknown in the DSL, and I’m not slowing down now, especially with the last piece of the puzzle coming together, and that is the game power. He has 8 homers in 56 games at High-A, the plate approach is still elite, and he keeps on racking up steals with 16 in 19 attempts. He is the complete offensive package, and even though he’s bad on defense, this is the type of bat to not care too much about that for fantasy.
4) (41) (252) Luis Pena – MIL, SS/3B/SS, 18.6 – I named Pena a Target this off-season in a DSL tier with Joswa Lugo, Yolfran Castillo, Yairo Padilla, Elvin Garcia and Jhonny Level, writing in his blurb, “Pena was a hit/speed breakout whose swing looks damn dangerous to me, and he’s not super small or anything at 5’11”. This could be the group where we find the next blow up. Take a lotto ticket or two here.” … and we did find the next blowup in this group, and that man’s name is Luis Pena. That explosive swing I couldn’t get out of my head has led to a power explosion with 5 homers in 35 games, and it comes with elite contact (11.5%) and speed (24 steals). He hits the ball hard, he doesn’t have any groundball issues, he pulls it … he’s the total package.
5) (6) (20) Bubba Chandler – PIT, RHP, 22.9 – The fact that Chandler hasn’t been called up already is just robbing baseball fans. Slow playing hitters is one thing, but pitchers with upper 90’s gas get hurt all the time. We don’t know how many bullets are in the tank. To let this man rot at Triple-A is baseball malpractice.
6) (10) (23) Chase Burns – CIN, RHP, 22.5 – Double-A was a complete joke for Burns with a 1.29 ERA and 36.4/2.6 K%/BB% in 42 IP, and while Triple-A has been slowing down tons of pitchers these days, I think Burns is ready for the challenge. We could see him in the majors by the 2nd half of the season. Chandler and Burns are in a tier of their own right now.
7) (3) (8) Leodalis De Vries – SDP, SS, 18.8 – He cooled off majorly with a .571 OPS in his last 26 games at High-A, but keep in mind that the Midwest League is a very tough league for hitters. His home park is one of the best places to hit in the league, and he has a .972 OPS there. On the road in tougher parks he has a .613 OPS. I’m not budging off Leo … well, I guess I am budging, but I’m not budging too far
8) (5) (9) Walker Jenkins – MIN, OF, 20.3 – Ain’t no way I can let an ankle injury impact Jenkins’ ranking. He just returned from the injury and after looking good in the lower minors, he’s back at Double-A for the last 2 games
9) (8) (32) Jesus Made – MIL, SS, 18.1 – I mean, he’s no Luis Pena … The .280/.389/.423 isn’t exactly a dominating triple-slash, but keep in mind he was still 17 years old for the first month of the season, and everything we loved about him in the DSL is transferring
10) (13) (13) Samuel Basallo – BAL, C/1B, 20.9 – 93.4 MPH EV with a 33.7% whiff% in 39 games at Triple-A really says it all. There is huge power, but don’t completely discount the hit tool risk. Having said that, he’s 20 years old, so I would bet on that improving as he gains more experience
11) (11) (10) Andrew Painter – PHI, RHP, 22.2 – I’ve hinted more than a few times that Painter doesn’t really look all the way back to where he was pre-injury, and with what we’ve seen from tons of Tommy John/internal brace returnees, that is really par for the course. The 3.86 ERA with a 26.9/11.8 K%/BB% in 21 IP at Triple-A is just not the bulletproof, basically perfect pitching prospect he was before the injury. The control hasn’t been as crisp and he’s not missing as many bats. I’m betting on him continuing to improve, but there is no guarantee
12) (17) (17) JJ Wetherholt – STL, 2B, 22.9 – Everything is transferring to Double-A. He’s exactly who we thought he was
13) (16) (16) Travis Bazzana – CLE, 2B, 22.9 – He’s almost exactly who we thought he was. That 26.2% K% in 33 games at Double-A is a tad higher than hoped. But he’s lifting and pulling and he’s running, so it’s a fantasy friendly profile. He’s currently out with an oblique strain since May 15th that is expected to keep him out for 8-10 weeks
14) (22) (19) Max Clark – DET, OF, 20.5 – The only thing missing from his great start to the season was the power/speed combo, so he added that back in with 3 homers and 7 steals in his last 25 games.
15) (40) (54) Kevin McGonigle – DET, SS/2B, 20.9 – Here is what I wrote about McGonigle in the latest Dynasty Rundown and my thoughts remain the same now, “I’ve underestimated McGonigle his entire career, and I’m ashamed of myself. Hit tool first high school prospects are not my favorite bucket to shop in FYPD’s, so he wasn’t an FYPD target for me, and that was a mistake. He doesn’t jump off the screen at 5’10”, 187 pounds, and that led me to underrated him after his excellent pro performance too. The little man discount took me out, and I pride myself on the little man discount. But all the underrating from me stops now, as he cracked a true power hitter’s bomb into the parking lot for his 2nd homer in 11 games at High-A. The plate skills are silly elite with a 7.7/21.2 K%/BB%, he hits the ball hard, he can lift and pull, and while he’s yet to steal a base this year, we know he has that too with 22 steals in 24 attempts in 74 games in 2024. He’s awesome and I’ve never given him the respect he deserves.”
16) (20) (43) Zyhir Hope – LAD, OF, 20.4 – He’s 1 for 3 on the bases in his last 50 games. That is just 1 steal since April 10th. That could be a bit of an upside capper for fantasy, especially with some hit tool risk here too
17) (23) (104) Bryce Rainer – DET, SS, 19.11 – I’ve been talking about it for most of the season, but shoulder surgery doesn’t seem to be that big of a deal for hitters anymore. Neto, Ohtani and Varsho all returned this season ripping dingers, arguably stronger than they’ve ever looked before. So I’m not fading Rainer at all due to the shoulder surgery. I closed out Rainer’s Top 1,000 blurb by writing, “Riley Greene might actually be the perfect comp here, and Detroit has done a great job developing Greene. Detroit got their SS version of Greene” … and he basically performed right to that comp. He’s a buy low off the surgery if you can
18) (49) (31) Aidan Miller – PHI, SS, 21.0 – The hit tool is getting a bit exposed at Double-A with a 27.2% K% and .234 BA, but he just turned 21, and he’s been better of late with a .264 BA in his last 28 games. The 6 homers and 22 steals are also damn exciting for fantasy
19) (107) (103) Eduardo Quintero – LAD, OF, 19.9 – Utterly obliterating Single-A with true across the board destruction, and the only nitpick from early in the year, the high K%, has been coming down of late too with a 19.6% K% in his last 21 games. He has zero groundball issues. Kid is a stud
20) (66) (181) Caleb Bonemer – CHW, SS, 19.8 – The high school talent in the 2025 FYPD class is popping all over the place, and Bonemer is leading the 2nd round charge, slashing .278/.419/.473 with 5 homers, 17 steals, and a 22.5/18.5 K%/BB% in 49 games at Single-A. He has the talent and power/speed combo to back up the numbers, He’s lifting and pulling. I’m all in on Bonemer
21) (135) (106) Theo Gillen – TBR, SS, 19.9 – Dominating Single-A, slashing .283/.438/.453 with 4 homers, 17 steals, and a 23.7/19.4 K%/BB% in 31 games. He was one of my favorite targets after the consensus top tier was off the board, so he most certainly has the talent to back up the numbers. There still might be a buy window here before his value explodes
22) (50) (71) Josue Briceno – DET, C/1B, 20.8 – Going bonkos at High-A with 8 homers in his last 14 games. That gives him 13 homers with a 173 wRC+ and 19.0/7.9 K%/BB% in 40 games on the season. This is the elite, middle of the order blowup that I warned you about this off-season when I named him a major target. And I’ve been naming him a target from before he got even a whisper of hype. I love this dude.
23) (32) (93) Arjun Nimmala – TOR, SS, 19.8 – One of the most visually dangerous righty swings in the game, and he’s backing it up with 9 homers and a 19.9/11.0 K%/BB% in 51 games at High-A. Age to level production, power, athleticism … there is nothing not to like
24) (43) (70) Jacob Misiorowski – MIL, RHP, 23.2 – We aren’t quite out of the woods yet with his control problems with 11 walks in his last 11 IP, which is definitely a bit scary, but a 12.3% BB% is still a career best, and I just can’t bring myself to fade his monster stuff with elite bat missing ability. Plus he’s in a great organization
25) (37) (24) Bryce Eldridge – SFG, 1B, 20.7 – 8 homers with a 27.2/10.5 K%/BB% in 39 games in the upper minors. We know who Eldridge is, and while the power is good enough to conquer San Francisco, I do think it shaves some upside off the top
