Three top fantasy baseball prospects - Thomas White, Charlie Condon, Joshua Baez - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Targeting high-upside prospects is key to finding success in fantasy baseball. Through the opening months of the season, managers have seen many prospects earn the all and make a high impact, including Payton Tolle, Ryan Waldschmidt, and Colt Emerson.
In this piece, we will spotlight three of the top prospects in the sport who are not only showcasing high-end talent at Triple-A but are nearing their MLB debuts.
Should fantasy managers stash these high-end prospects? Let's dive in!

Thomas White, SP, Miami Marlins
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 18 2/3 IP, 4.34 ERA, 1.45 WHIP, 25 SO, 9 BB
Despite being on the 7-day injured list, Miami's Thomas White holds the No. 3 spot on our list. Last week, it appeared White was on the fast track to the big leagues as Braxton Garrett was optioned to Triple-A. Robby Snelling, who was recently promoted, was sent to the 15-day injured list.
However, White would then hit the injured list himself for a much more minor issue. While Snelling is set to miss the early part of the 2026 season due to an internal brace surgery, White is only battling a minor shoulder issue. At the time of the injury, the team did not express much concern, which suggests the southpaw could be back in action sometime in early June.
Even though he is currently not on the mound, his path to the majors remains very clear. As soon as he is active, he could easily move to the top spot on our stash list.
Before his injury, White made five starts with Triple-A (18 2/3 innings) and posted a 4.34 ERA with a 1.35 WHIP. He struck out 25 hitters and walked nine. He suffered an injury during camp, which kept him out at the beginning of the season, which is why his innings count is much lower than that of other names on this list.
In the 2025 season, White progressed through the Miami system at an impressive rate, logging 89 2/3 innings across three levels (High-A, Double-A, and Triple-A), posting an elite 2.31 ERA, 1.18 WHIP, and a 145:45 K: BB. His command has been a blemish on his profile, but his strikeout upside is among the best in the minor leagues.
With Miami lacking much depth in its rotation, White could get the call before the end of the first half if he can quickly move past this injury.

Charlie Condon, 1B, Colorado Rockies
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 47 G, .257/.386/.453, 12 2B, 7 HR, 4 SB
Condon is the former third overall pick in the 2024 MLB Draft. He's currently slashing .257/.386/.453 with seven home runs and four stolen bases in 211 plate appearances in his age-23 season at Triple-A. While these numbers don't pop off the page, you have to like the 15.2% walk rate with a reasonable 25.1% strikeout rate.
Charlie Condon got ALL of this one!

The Rockies are a rebuilding team that has fallen on hard times lately. They're ice cold right now, so they may want to start to see what they have with their best prospects. TJ Rumfield is playing first base for the Rockies right now, but he's a completely unproven hitter who is starting to slow down, going 0-for-8 in his last three games.
There's also the chance that Rumfield can just move to DH while Condon takes over at first base. It may take until the All-Star break, but when it happens, Condon has power upside that you'll want to target, especially since he gets to hit at Coors Field.
Keep a close eye on Condon in the minors because if he heats up, we could see him force the Rockies' hand.

Joshua Baez, OF, St. Louis Cardinals
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 49 G, .254/.335/.569, 8 2B, 16 HR, 11 SB
While his place as a corner outfielder and his propensity to swing and miss have limited his prospect ranking to 67th according to MLB.com, he is a considerably better prospect in terms of overall fantasy upside.
This can easily be seen by his 2025 performance, where he slashed .287/.384/.500 with 20 home runs and 54 stolen bases in 117 games between High-A and Double-A. He's seamlessly carried that power and speed into Triple-A this season, launching 16 homers and stealing 11 bags so far. While his strikeout rate has jumped back up to 31.6% and his average sits at a non-elite .255, he would still be a must-add for fantasy purposes thanks to his 60-grade power and his aggressiveness on the basepaths.
The 22-year-old has been especially hot as of late, posting back-to-back two-homer games on May 26 and May 27, while tacking on another home run on May 28. His homers aren’t cheap either, as the youngster has put up a 94th percentile max exit velocity and 98th percentile barrel rate this season.

With players such as Bryan Torres and Nelson Velázquez picking up starts in the outfield, it could be sooner rather than later that Baez gets the call. He’d be a must-add in all leagues once he does, as his sky-high upside could make him fantasy relevant in even the shallowest of leagues.
