Eric Cross' Top 125 Dynasty Prospect Rankings for Fantasy Baseball (May 2026)

May 28, 2026

Eric Cross' updated fantasy baseball prospect dynasty rankings -- his top 125 prospects for fantasy baseball from his May 2026 rankings update. Check out his dynasty prospect risers and fallers.

In the blink of an eye, we're already one-third of the way through both the Major League and minor league seasons. Many of the top prospects entering the season have graduated, giving the top of these rankings a different look than in March and April. And per usual, we've already seen plenty of notable breakouts flying up rankings.

These MLB prospect rankings are geared toward standard 5x5 fantasy baseball leagues (AVG) and consider many factors, including performance to date, scouting grades, future projection, and video and data analysis. Or, as I like to call it ... "PPP," which stands for profile, performance, and projection.

While these dynasty fantasy baseball prospect rankings are more slanted toward long-term fantasy value, proximity and short-term value do play a part in where a prospect lands in my rankings. If you want to see the full top 500, then head on over to my Patreon!

Fantasy Baseball Prospect Rankings Notes

Devin Fitz-Gerald, Washington Nationals

It's been a phenomenal start to the season for Devin Fitz-Gerald. In 42 High-A games, Fitz-Gerald is slashing .297/.411/.618 with 26 extra-base hits, 12 home runs, 11 steals, and nearly as many walks (28) as strikeouts (30). His 161 wRC+ is the second-best mark in the minor leagues for all prospects age 20 or younger with at least 100 plate appearances this season. Only Franlin Arias ranks higher with a 171 wRC+.

Not only does Fitz-Gerald have a great approach at the plate with a 14.1% walk rate, 15.2% strikeout rate, and an 8.6% SwStr rate, but he's also making contact at an 80% clip while showcasing more power than he did last season. And while he's not a burner, Fitz-Gerald has enough speed and baserunning acumen to be a 20-steal threat long-term to go with more than 20 home runs and a good AVG/OBP.

As you can tell from my ranking, I'm fully on board the Fitz-Gerald hype train.

Eric Hartman, Atlanta Braves

If Fitz-Gerald isn't the biggest breakout prospect so far in 2026, it's because Eric Hartman is. In 43 High-A games, Hartman has already racked up 11 doubles, 13 home runs, and 17 steals to go along with a .302/.383/.609 slash line and a 156 wRC+. The stolen bases are on pace with last season, and so are the approach and contact rates, all of which are nearly identical to last season, with a 74% contact rate, 10.4% walk rate, and 22.8% strikeout rate.

However, Hartman is impacting the ball a lot more, already hitting eight more home runs this season than he did in 46 more games last season. So while Hartman doesn't possess the same floor as Fitz-Gerald, specifically in the AVG/OBP department, you can make a case for Hartman having the higher power/speed ceiling due to his speed impact. Fitz-Gerald projects slightly better in the power department, though.

Not bad for a 20th-round pick, huh?

Ethan Salas, San Diego Padres

If you've followed my work over the last few years, you'll probably know that I've been lower on Ethan Salas than most. Most of that was back in 2023 when he got pushed to Double-A as a 17-year-old, and his rankings shot up to Top-10 or Top-20 levels. That was obviously way too high back then, but I'd be lying if I said I wasn't intrigued by how Salas looks this season.

Salas has slashed .303/.364/.503 with eight doubles, seven home runs, and nine steals in his first 40 Double-A games this season. He's still making above-average contact with an 85% contact rate, along with a solid 9.2% walk rate and 18.4% strikeout rate. But the biggest difference for Salas this season, outside of the fact that he's 100% healthy, is the impact he's made in the power department.

Salas is hitting the ball much harder this season, which is the area I had concerns about over the last few seasons. If he continues to show this level of contact and power, while stealing a bag here and there, Salas could wind up as an impactful catcher for fantasy purposes. And yes, I'm fully aware my Salas ranking is probably too low. He's going to move up even more in my next update if this continues.

Seaver King, Washington Nationals

After a rough 2025 season, Seaver King has bounced back nicely so far in 2026. In 41 games between Double-A and Triple-A, King has slashed a robust .344/.429/.581 with 22 extra-base hits, six home runs, and six steals. His hot start in Double-A earned him a promotion to Triple-A, where he has a .391/.444/.696 slash line in his first six games.

King is making contact at a similar 78% clip this season, but he's shown exponentially more patience at the plate, which has really helped his overall offensive output tick up this season. After walking at just a 5.8% clip last season, King is walking at a 12.5% clip this season while keeping his strikeout rate in check at 20.5%.

Long-term, King has enough power to be a 15-20 homer bat who could push or exceed 25 steals annually while hitting for a decent average. And if the higher walk rate sticks, the OBP might not be too shabby either.

Karson Milbrandt, Miami Marlins

On the pitching side of things, arguably the biggest breakout performer through the first two months of the season jas been Miami's Karson Milbrandt. In 42.1 Double-A innings, Milbrandt has posted a stellar 1.06 ERA, 0.90 WHIP, 8.7% walk rate, and a 39.1% strikeout rate. Among the 158 minor league pitchers with at least 40 innings pitched this season, Milbrandt has the 2nd highest strikeout rate, 2nd highest K-BB rate, and the 3rd lowest BAA at .164.

Milbrandt works with a deep five-pitch arsenal, headlined by three above-average or better offerings in his curveball, cutter, and mid-90s 4-seamer. And on top of that, Milbrandt has dropped his walk rate from 12.3% last season to 8.7% this season. The higher walk rate was always a concern with Milbrandt, so it's highly encouraging to see him pounding the zone more often and limiting the walks better this season. He's a strong buy in dynasty leagues.
