Draft season always produces a handful of players who slip through the cracks. Sometimes it’s a former top prospect finding a better situation. Other times it’s a veteran who suddenly solves a problem that held back his production. On a recent Fantasy Fest discussion at FantasyPros Fantasy Baseball Podcast, analysts highlighted several undervalued names who could outperform their current draft cost in 2026 fantasy baseball leagues. Here are their favorite must-have fantasy baseball sleepers of 2026.

Fantasy Baseball Sleepers to Draft
Here are four fantasy baseball sleepers worth targeting if you want to squeeze extra value out of the middle and late rounds.
Andrew Vaughn might be the definition of a post-hype sleeper.
A former third overall pick, Vaughn never quite delivered on expectations with the White Sox. But a midseason move to Milwaukee sparked something. In 64 games with the Brewers, Vaughn posted a .308/.375/.493 slash line with nine home runs and looked far more comfortable at the plate.
The context matters. Milwaukee has quietly become one of baseball’s smartest organizations. The Brewers maximize player development and often unlock value from hitters who struggled elsewhere. Vaughn could be the next example.
The projection here is fairly straightforward. If the Brewers deploy him in the middle of a lineup full of high-OBP hitters, Vaughn has a path to something like .270 with 20-25 homers and around 90 RBI. That kind of production plays very well at corner infield.
The bigger appeal is cost. His ADP sits outside the top 200 in many formats, sometimes even closer to pick 250 or later depending on the platform.
In other words, you’re getting everyday playing time and middle-of-the-order upside at a near free price.
Max Muncy is one of those boring veterans who quietly win fantasy leagues.
Last season included a fascinating turning point. After April, Muncy began wearing glasses and claimed he could finally see pitch spin clearly. The result was a massive surge in production. From that point forward, he posted a 166 wRC+ with 19 home runs and a near .970 OPS.
That might sound like a quirky narrative, but improved vision can legitimately change a hitter’s ability to recognize pitches.
There’s also a positional element at play. Third base looks surprisingly shallow heading into 2026 drafts. Once the early stars are gone, the player pool gets thin quickly.
Muncy solves that problem.
Even with some age-related risk and occasional rest days, the expectation remains 25-30 home runs with strong RBI totals hitting in the Dodgers lineup. If the batting average settles around league average, he’s a major profit.
Considering his ADP often sits outside the top 200 on several platforms, Muncy fits perfectly as a late starting third baseman or corner infield solution.
Daylen Lile may be the least recognizable name on this list, but his skill set screams fantasy upside.
In a partial rookie season, Lile produced an impressive .299/.347/.498 slash line while flashing both speed and emerging power. If you pace those numbers over a full season, you’re suddenly looking at a potential 15-20 homer and 15-20 steal player.
The speed is real. Lile ranked in the 92nd percentile in sprint speed and even legged out 11 triples in just 91 games. That kind of athleticism creates extra fantasy value through stolen bases and infield hits.
Washington may not be a great real-life team yet, but fantasy value doesn’t require a winning roster. It requires playing time and skills.
Lile should have both.
Because he flew under the radar during his rookie stretch, his ADP remains outside the top 200 in many drafts. That makes him an ideal upside pick if you’re looking for balanced category contributions in the outfield.
Pitching prospects often fade from the fantasy spotlight after injuries, and Cade Cavalli is a perfect example.
Before Tommy John surgery, Cavalli was widely considered one of baseball’s top pitching prospects. Now fully healthy and named Washington’s Opening Day starter, he’s positioned for a breakout.
The underlying metrics are intriguing. Cavalli features four pitches with plus “stuff” grades and showed strong contact suppression despite uneven results last year. He allowed a sub-5 percent barrel rate, an 87 mph average exit velocity, and generated 55 percent ground balls.
The strikeouts could be the key improvement.
While his strikeout rate sat around 18 percent, his 12.5 percent swinging strike rate suggests a much higher ceiling, potentially in the 25 percent range. If that correction happens, Cavalli suddenly looks like a legitimate mid-rotation fantasy asset.
Because the results haven’t fully caught up to the talent yet, his draft cost remains extremely low.
That’s exactly the type of profile worth targeting in the late rounds.
Fantasy Baseball Sleepers: Takeaways
- Andrew Vaughn offers strong corner infield value with a path to .270, 20-25 HR, and 90 RBI in Milwaukee’s lineup.
- Max Muncy remains a power source at a thin third base position and could easily reach 25-30 homers again.
- Daylen Lile brings speed and emerging power, making him a potential 15-20 HR / 15-20 SB breakout candidate.
- Cade Cavalli still has top-prospect upside and could deliver a major strikeout jump if his underlying metrics translate.
- All four players are currently available outside the top 200 picks in many drafts, making them ideal mid-to-late round targets.
- Prioritize sleepers with clear playing time and skill growth indicators, not just hype.
