Three top fantasy baseball prospects - Max Clark, Jett Williams, Joshua Baez - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Targeting high-end prospects who are on the verge of earning the call to the majors is key to winning in fantasy baseball. Those who stashed Payton Tolle ahead of his promotion this season secured a high-end producer in the strikeout category.
Below, we will spotlight three of the top hitting prospects who are not only all at the Triple-A level but have flashed high-end potential with their respective clubs.
Should fantasy managers stash these high-end prospects? Let's dive in!

Max Clark, OF, Detroit Tigers
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 44 G, .272/.342/.400, 13 2B, 2 HR, 11 SB
Clark was the third overall pick in the 2023 MLB Draft, signing for more than $7.6 million out of high school. He's not a five-tool prospect, but he's regarded as a pure athlete with tremendous upside, making him a very intriguing stash in fantasy baseball leagues.
There isn't much power in Clark's swing, as he launched just 14 home runs last year, and he has only one home run across 41 Triple-A games this year. However, he makes up for it with his speed and ability to put balls in play. He's up to 10 steals already and could threaten to surpass his previous career-high mark of 29.
The swing decisions have also been encouraging. Clark has chased 23.38% of the time, which ranks in the 72nd percentile. He also has a 14.4% whiff rate (94th percentile), 15.3% strikeout rate (86th percentile), and 91.78% zone contact rate (92nd percentile).
Even though there isn't a ton of power in Clark's offensive profile, his swing decisions and speed are encouraging enough to justify rostering him in many fantasy baseball leagues, especially since he could be called up for his MLB debut in June.
Clark is currently available in 95% of fantasy leagues, and he ranks as the #2 outfield prospect in RotoBaller's latest redraft rankings.

Jett Williams, INF, Milwaukee Brewers
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 49 G, .247/.365/.398, 7 2B, 5 HR, 11 SB
The Mets selected Williams with the 14th overall pick in the 2022 MLB Draft. One of the top prep prospects of his class, Williams inked a $3.9 million signing bonus out of high school. He developed for several years in the Mets' system before being traded to the Brewers this past offseason.
Williams has a very encouraging blend of power and speed, which makes him a perfect fit for the Brewers and their aggressive offensive philosophy at the major league level. He hustles well on defense, and he possesses a versatile background with plenty of experience at third base, shortstop, and center field.
From last year to this year, Williams' walk rate has increased while his strikeout rate has decreased. He has demonstrated great swing decisions with a 20.31% chase rate, and his 20.4% whiff rate also ranks among the top one-fifth of batters in Triple-A.
Meanwhile, from a power perspective, although we are encouraged by his 17 homers last year and five homers so far this year, we wouldn't mind seeing higher exit velocities. His 102.1 mph EV90 in 2026 ranks among the bottom half of Triple-A hitters, and he has maintained a suboptimal 32.2% hard-hit rate.
Nevertheless, Williams' blend of power and speed is very encouraging for fantasy baseball. The good swing decisions should translate to decent contact results when he gets called up to the majors, and he'll find his way into some power even if the EVs remain below average.
Williams has been playing third base in Triple-A, but he maintains shortstop and outfield eligibility in plenty of fantasy baseball leagues. In RotoBaller's latest redraft rankings, Williams checks in as the #3 shortstop prospect and #9 outfield prospect.

Joshua Baez, OF, St. Louis Cardinals
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 44 G, .233/.320/.483, 8 2B, 11 HR, 11 SB
Joshua Baez Closing in on Debut After Recent Home Run Barrage? https://t.co/TPX8nf4Mg1
— RotoBaller MLB (@RotoBallerMLB) May 20, 2026
Baez has a .239/.315/.497 slash, which is a bit underwhelming, but the power and speed upside is enormous, as highlighted by his 11 home runs and 10 stolen bases in 181 plate appearances at Triple-A.
Remember, this is a hitter who put up 20 homers and 54 steals across all minor league levels last year, so the ceiling is quite high. Once Baez is finally recalled to the Cardinals, you're going to want him on your fantasy teams.
The Cardinals are a rebuilding team, but they've surprisingly gotten off to a 28-21 start, so they can be patient with Baez. However, it's only a matter of time before he forces their hand.
Having another outfielder with strong tools to go along with Jordan Walker would make the Cardinals' lineup even more exciting. Swapping Nathan Church for Baez would raise the ceiling of this group. Keep a close eye on Baez, as he's my favorite stash on this list. He could be exactly what your team needs.
