Top 100 Fantasy Baseball Prospects - Dynasty Rankings for Non-Debuted Prospects (July Updates)

Kevin's updated top 100 fantasy baseball prospect rankings for MLB prospects yet to debut in the majors. His July 2025 dynasty prospect rankings for fantasy baseball.

Some exciting content news for you dynasty baseball fans -- my Top 100 Fantasy Baseball Prospect Rankings will now be updated monthly as a recurring series, and today I'm back with my updated rankings for July.

The prospect rankings update will usually come a little later in the month, but I wanted to get out one update before the MLB draft and the craziness of adding hundreds of new names to the fantasy prospect pool.

This fantasy baseball prospect rankings list will only have non-debuted prospects. I'm also re-sharing some of my general prospect ranking philosophies for those who are new to my rankings.

• Upside over proximity: the best prospects are often closer to the majors than they seem, and the low upside guys will always have factors that block their chances of being too fantasy relevant
• I will probably be lower on your favorite pitching prospect than most lists: I've just seen this film before, and I didn't like the ending too many times
• I am a sucker for age-to-level production- there's a reason why the top NBA draft pick every season is a college freshman or teenager playing overseas against grown men, similar analysis can be utilized to value baseball prospects
• What you did as an amateur matters very little to me once you have a solid sample size of professional games under your belt

Fantasy Baseball Prospect Dynasty Rankings: Top 100

Prospect details can be found in the rankings table below, with some thoughts on a few exciting prospects. The top of my prospect list likely won't change too much each month, as my top 20-25ish prospects are who I would consider the cream of the crop, and it's harder for a prospect to move in or out of that range.

Check here for more thoughts on my Top 20 prospects, as I did a long write-up on most of them last month, and check here to see last month's Top 100 prospect rankings list.

One note: I know one of the first things that I look at when I see a prospect list is what their previous ranking was. I would say some prospect risers and fallers have tangible things they've done since the last ranking to justify that change.

However, some risers and fallers are just me recalibrating my thoughts on a prospect. I won't hesitate to adjust a player's ranking, even if it might make my previous ranking "look bad". Let's get to it:

No. 22: Theo Gillen, OF, Tampa Bay Rays

Is Theo Gillen the most underrated prospect from last year's MLB Draft? Obviously, the college stars that have already made it to the majors and the arguable new overall top prospect, Konnor Griffin, have generated the most buzz. Still, I feel like no one is talking about Gillen.

This past offseason, I was a little worried about Gillen as his first stint of pro ball was pretty rough. In 34 PAs at Low-A, he only had one XBH and struck out 41.2 percent of the time. Gillen was a guy I liked as a prep hitter, but I had to downgrade him quite a bit, even though this was a tiny sample.

This season, he's put my concerns about him to rest very quickly. Back at Low-A as a 19-year-old, Gillen has a 156 WRC+ so far this season, which is fifth among qualified hitters at the level. He's behind Griffin, Eduardo Quintero, and two guys who are 22 and 23, respectively.

Gillen has five HRs and 29 SBs, but what has really impressed me is his mature approach at the plate. He's striking out 23.6 percent of the time while walking 21.1 percent of the time, which is the second highest among qualified hitters at the level.

I'll have to remember Gillen when I'm doing my offseason list as an example to not overreact to poor small sample sizes from new draftees, especially prep players. They're teenagers who just got millions of dollars and had the biggest jump in competition of their baseball careers. It's ok if they're not that good right away.

No. 28: Jonah Tong/No. 42 Nolan McLean, P, New York Mets

We're seeing what the Mets' pitching lab is cooking at the Major League level as they've made lemonade out of lemons and built a substantial rotation out of castaways like Clay Holmes, Sean Manaea, and Luis Severino over the last couple of seasons.

However, very soon we'll see what they've been cooking at the minor league level as two of their top pitching prospects are now on the doorstep of the majors.

Nolan McLean could be the next man up for the Mets as he's been excellent so far this season between Double-A and Triple-A. He has a 2.17 ERA and 1.17 WHIP across 87.0 innings. He also has a 26.6 percent K-rate and 10.6 percent BB-rate.

What makes his season even more impressive is that it's only his first full season as a full-time pitcher. He was drafted in 2023 as a two-way player, and the Mets were still trying to develop his bat into the 2024 season. He's a guy who is getting better at a rapid rate and just had the best start of his professional career.

McLean Masterclass!

While we might need to wait a little longer to see Tong in the majors, he has some of the highest upside of any pitcher in the minors. Tong has struck out over 30 percent of batters he's faced at every stop on his minor league career, and he's striking out 40.8 percent of batters so far this season in Double-A.

He also has an excellent 1.83 ERA and .93 WHIP. His BB-rate is a tad high at 11.4 percent, but that's palatable given his amazing strikeout ability. Tong has a bit of a funky over-the-top delivery, emulating his favorite player, Tim Lincecum. If he can get even close to his idol, we'll be looking at a fantasy ace.

How about this strikeout from Jonah Tong?!

No. 50: Edward Florentino, 1B/OF, Pittsburgh Pirates

I will admit that Edward Florentino is a prospect I was not too familiar with coming into this season. He was starting to heat up around the time of my last update, and I put him on my spreadsheet as a prospect to watch, but I could not have anticipated he would be the rocket ship he's been over the last few weeks.

Florentino had a very strong season in 2024 as a 17-year-old in the DSL, but he didn't get the hype that the likes of Jesus Made or Luis Peña received. He had a 149 WRC+ with five HRs and eight SBs while walking (20.0 percent) more than he struck out (18.9 percent).

This season, he's done nothing but rake, both in the Complex and now in Low-A. In 113 PAs in the Complex, he had a 191 WRC+ with six HRs and six SBs while walking 14.2 percent of the time and only striking out 19.5 percent of the time.

Since being promoted to Low-A, he hasn't missed a beat. He has a 167 WRC+ with four HRs and nine SBs in 77 PAs. While his K-rate has increased a little bit to 22.1 percent at Low-A, one fascinating aspect of his profile is that his contact rate has gone up to 85.2 percent. This is an absurd contact rate for someone with his power, which is already being displayed in games.

Edward Florentino:

.364/.450/.818 in the month of July 🔥

Yup, .818 slugging!

4 HRs & 3 doubles in 9 games will do that pic.twitter.com/AGC7x3d0za

It's not normal for an 18-year-old to be displaying this level of power and hit tool in full-season ball. I know the prospect community has called Josue De Paula and Lazaro Montes "Baby Yordan," but could Florentino be the next in line to get that aggressive comp?

No. 52: Owen Caissie, OF, Chicago Cubs/No. 57 Spencer Jones, OF, New York Yankees

I wrote about these two guys in my prospects to stash series earlier this week because they're each simply too hot to ignore and have similar profiles- big power with questionable hit tools.

When I talk about prioritizing upside, that upside comes in multiple different forms. My usual preferred upside form is teenagers tearing up the low minors, but sometimes it comes in the form of guys with prodigious power that might not ever hit enough to be fantasy relevant.

But what if they do???

Owen Caissie and Spencer Jones are both homering almost every night in Triple-A. Caissie has a 144 WRC+ with 19 HRs so far this season, but he's striking out 30.2 percent of the time. His K-rate has hovered around 30 percent for most of his minor league career.

"If you make a mistake to this guy, he's gonna do that to it!"

Spencer Jones had a 186 WRC+ in Double-A this season, which is the highest at the level for any player with at least 200 PAs. He had 16 HRs but struck out 33.7 percent of the time. Since moving up to Triple-A, he's been even better.

In Triple-A, he already has six HRs in 12 games. He has a 229 WRC+ while striking out 28.8 percent of the time.

Not horrific K and chase rates so far. Whiff and zone contact rates are still really bad.

But when he does make contact? He’s obliterating the ball. pic.twitter.com/yRdWuOY5lu

— Yankees Prospect Watch (@NYY_Prospects) July 12, 2025

I'm not overly confident that Caissie or Jones will make enough contact to be fantasy stars. Could they end up being Joey Gallo-ian? If they do make enough contact, you're looking at two guys with some of the biggest power upside in the minors.

No. 74: Juneiker Caceres, OF, Cleveland Guardians

It's pretty rare for a 17-year-old to play stateside. It's even rarer for them to play as well as Juneiker Caceres has been playing this season.

Maybe we should've seen some of this coming, as he had a very impressive season as a 16-year-old last season in the DSL. He had a 144 WRC+, which was tied for the highest for a 16-year-old in the DSL, while walking more than he struck out. He didn't hit any HRs, but he did have 17 XBHs.

This season at the Complex, Caceres has been even better than he was in the DSL. He has a 158 WRC+ while walking (17.6 percent), much more than he's striking out (11.5 percent). He's also starting to get into some game power with three HRs.

Juneiker Caceres is a 17 year old at the Rookie level that the @StatlineScout model is suggesting that you be aware of. He is currently slashing .312/.444/.545 with 3 home runs more BBs (19) than Ks (13) ✍️

It's crazy to say for a player so young, but Caceres might be too good for Complex-level pitching. If the Guardians bump him up to Low-A and he continues to hit like this, he should fly up prospect rankings before the offseason.

The "Other Mudcats"

No. 64: Braylon Payne, OF/No. 76: Josh Adamczewski, 2B/No. 91: Marco Dinges, C/No. 95: Eric Bitonti, 1B/3B, Milwaukee Brewers

I could probably write a whole article about all of the exciting prospects that have donned a Mudcat uniform this season. The Brewers are brewing something special at their Low-A affiliate in Carolina.

Made and Peña have stolen most of the headlines and have gotten most of the love from prospect rankers due to how advanced they've been at such a young age. However, this squad has been absolutely loaded offensively and had four other players in my Top 100, so I had to give some special recognition.

I'm not some special ranker, but six players at one level for one org in anyone's Top 100 prospects is absolutely insane.

Braylon Payne actually got a small taste of Low-A last season as a 17-year-old after being drafted in the first round by the Brewers and was phenomenal as he had a 225 WRC+ in 19 PAs.

This season has been a bit up and down, but the overall stat line is very solid for an 18-year-old at Low-A. He has a 124 WRC+ with six HRs and 22 SBs. He is striking out 28.4 percent of the time, but has a very impressive 15.3 percent BB-rate. He is also starting to heat up a bit and could see himself rise in my next update.

Josh Adamcezski has been underrated since he was drafted in the 15th round in 2023. However, all he does is hit. He doesn't have much power or speed, but he has put up amazing ratios throughout his minor league career.

He had a 157 WRC+ in 2024 at the Complex with a taste of Low-A and a 175 WRC+ in mostly Low-A this season. He's had super high BABIPs at every level, and he doesn't have big upside, but there's a place in fantasy for guys who simply just hit like he does.

Marco Dinges is the only member of this quartet who has been promoted out of Carolina. He was drafted out of college, so there was some expectation that he'd move faster than the others. Dinges dominated Low-A this season with a 203 WRC+.

He had three HRs and walked (18.8%) 50% more than he struck out (12.5%). Since getting the bump to High-A, his absurd plate approach has worsened a bit as his K-rate is up to 19.7 percent and his BB-rate is down to 9.8 percent, but he's hitting for more power as he already has six HRs at the level in about the same amount of PAs.

Eric Bitonti is the potential Caissie/Jones type that I talked about earlier in this group. He has already hit for a ton of game power for a player of his age. He hit 16 HRs between the Complex and Low-A last season as an 18-year-old and is already up to 14 this season, all in Low-A.

2-0 fastball to Eric Bitonti?

You know what happens next 😉💥 pic.twitter.com/kEf8OxDEyU

However, his K-rate has ballooned to 33.7 percent this season. His K-rate was under 30 percent at both levels last season, so there is hope that he can bring it back down, which he'll need to do to survive against better pitching. Like Caissie and Jones, he has massive power upside if the hit tool is palatable.
