5 Fantasy Baseball Prospects Dynasty Managers Need to Know

Dynasty fantasy baseball players are always looking for the next wave. Sometimes that means chasing top-10 fantasy baseball prospects everyone already knows. Other times, it means getting ahead of the market before the rest of your league catches up. This week’s group leans heavily into the second category.

Fantasy Baseball Prospects to Know

These are prospects producing at multiple levels of the minors who are beginning to force their way into bigger conversations. Some are close to the majors. Others are years away. But all five are trending up fast in dynasty formats.

Yohandy Morales

The conversation around Washington’s system lately has centered on other names, but Yohandy Morales is quietly putting together one of the loudest offensive seasons in Triple-A.

Morales is hitting .355 with 10 home runs, and the underlying power metrics stand out just as much as the surface stats. The transcript highlighted a 54 percent hard-hit rate and a 108.1 mph 90th percentile exit velocity, putting him in similar territory to some much more heavily discussed prospects.

The most interesting fantasy angle here is the potential buying opportunity. While other Nationals prospects dominate headlines, Morales appears to be flying under the radar despite producing elite contact and hard-hit numbers.

There’s also a possible path to the majors sooner than people realize. With Washington already shuffling pieces around the infield, Morales could enter the picture quickly if the organization wants another bat with impact potential.

For dynasty managers, this is exactly the type of profile worth targeting before the market catches up.

Karson Milbrandt

Karson Milbrandt is becoming impossible to ignore.

The Marlins right-hander owns a 1.06 ERA through eight Double-A starts with 63 strikeouts across 42 innings. Just as important, the control issues that previously created concern appear to be improving.

The pitch mix is deep. Fastball, curveball, slider, and cutter all got mentioned in the discussion, with the breaking stuff generating significant swing-and-miss results. The improved walk rate may be the biggest development of all.

Milbrandt was described as one of the hottest pitching prospects in the minors right now, and there’s growing belief he could push himself into top-100 prospect territory in short order.

The fantasy takeaway is straightforward. In dynasty leagues with meaningful minor league systems, he probably should not be available anymore.

There may not be a major league debut coming this season, but the stock is rising rapidly.

Mike Sirota

Mike Sirota has done nothing but hit.

After spending most of the year at High-A before recently earning a promotion to Double-A, Sirota owns a .322 batting average with seven home runs, eight steals, and an absurd .473 on-base percentage.

The Dodgers organization appears to have unlocked another level in his offensive game after acquiring him from Cincinnati. The discussion emphasized how much development progress he’s made since the move.

Fantasy managers already know about several high-end Dodgers prospects, but Sirota sounds like the next name climbing into that tier.

The combination of batting average, plate discipline, and enough power-speed production gives him a chance to become a major riser in prospect rankings over the next year.

There was even discussion that his trajectory could eventually push him toward top-25 overall prospect status if the offensive breakout continues.

That kind of upside makes him a strong dynasty stash now before the hype fully arrives.

Eric Hartman

Eric Hartman may be one of the biggest helium prospects in fantasy baseball right now.

A 20th-round pick from the 2024 draft, Hartman has exploded offensively with 13 home runs, 17 stolen bases, a .301 batting average, and a .381 OBP before June.

The fantasy appeal is obvious. Few players in the minors are producing this kind of power-speed combination right now.

There’s still some caution attached to the profile. Last season, Hartman hit just five homers while relying heavily on stolen bases, so evaluators want to see the power gains hold as he climbs levels.

Still, the production has become impossible to overlook.

The transcript even referenced some fantasy prospect evaluators already placing Hartman inside their top-25 fantasy prospect rankings.

For dynasty managers, this is the classic early investment profile. The price is climbing fast.

Luis Hernandez

Luis Hernandez is the furthest away from the majors on this list, but he may also carry the biggest long-term ceiling.

The 17-year-old Giants shortstop is already playing stateside rookie ball and reportedly impressed immediately, including opening his professional career with home runs as his first three hits.

The discussion around Hernandez focused heavily on the quality of the bat for his age. The swing, raw power, and overall offensive feel were described as rare for a player this young.

While there are still defensive questions and some uncertainty about whether he sticks at shortstop long term, the offensive upside is what matters most in fantasy formats.

The comparison wasn’t direct stylistically, but the expectation is that Hernandez could rapidly climb prospect rankings the same way other breakout teenage hitters have in recent years.

The takeaway here is simple. Dynasty managers in deeper formats should get familiar with the name now because the price tag may look very different a year from today.
