Three top fantasy baseball prospects - Spencer Jones, Mick Abel, Dylan Beavers - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
Fantasy managers have seen many high-end prospects get the call to the major leagues and make an immediate impact this season. For example, several top pitchers like Chase Burns have flashed high strike potential while Nick Kurtz has shown elite power production.
In this piece, we will look at a top prospect who recently earned the call and two of the top performers at Triple-A and determine whether they should hold a spot on our bench.
Should those players be left on the waiver wire, or should fantasy managers add them before their breakout? Let's dive in!

Spencer Jones, OF, New York Yankees
Current Level: AAA
Availability: 15% rostered
2025 AAA Stats:38 G, .296/.371/.618, 7 2B, 14 HR, 15 SB
Jones' career so far has been a rollercoaster, to say the least. It's been a story of extremes on both ends of the spectrum, as Jones can fluctuate from being a bottom-tier minor leaguer to a top-tier prospect in the matter of months. FanGraphs even defined his strikeout tendency as "bust-indicating" in 2024, comparing him to Franchy Cordero. However, he has since rebounded with 30 homers this season and a 26 percent strikeout rate at Triple-A.
Jones' walk rate has gone up this season, but what's been most impressive is his ability to hit home runs. His power output has been unparalleled in Minor League Baseball, as he sports a .640 slugging percentage and 183 wRC+. The strikeout, chase, and whiff rates are still far from ideal, but they're a little more forgivable now that Jones is mashing a homer nearly every other game.
Jones really seemed to turn the corner in the month of July when he slashed .419/.477/.946 with 11 home runs and seven stolen bases. He posted a .527 ISO and 253 wRC+. Meanwhile, he maintained a solid 10.2 percent walk rate while cutting his strikeout rate down to a respectable 22.7 percent.
While it may seem hard to find a spot on the MLB roster with a crowded Yankee outfield, given their recent inconsistencies in August, Jones could look to be a much-needed park plug to this offense.
For now, he is worth stashing in deeper 12+ team outfield formats for his elite power upside.

Mick Abel, SP, Minnesota Twins
Current Level: AAA
Availability: 5% rostered
2025 AAA Stats: 15 1/3 IP, 1.76 ERA, 0.85 WHIP, 23 SO, 6 BB
Abel took a massive step forward with command this year and saw his fastball velocity tick back up. Across 83.1 Triple-A innings, Abel has a 2.16 ERA with a 1.16 WHIP, a substantial difference from the 6.46 ERA we saw in 2024. Abel also made his MLB debut with the Phillies before being traded to Minnesota at the 2025 deadline for Jhoan Duran.
Abel’s fastball is averaging 96 mph this year and has topped at 99 mph with solid traits. The bat-missing has ticked up on the pitch, and Abel is creating more than 16 inches of IVB from a 5'6" release height. The flat VAA stands out in a big way, and Abel also creates eight inches of horizontal movement while having exceptional spin rates and active spin. The sinker plays well off it, giving him the ability to get groundball outs when needed.
The slider averages around 87 mph with a gyro shape, but is almost close to bullet spin. While it has missed plenty of bats, it is the curve that has been the best breaking pitch of the two breakers. The curveball shows excellent depth and a two-plane break, sitting around 82 mph.
Abel has not used the changeup much, but the upper-80s offering does have good fading action to it and respectable whiff rates. The improvements in the arsenal and command this year have been notable. Having a more open opportunity in Minnesota, don't be surprised if we see Abel in the Twins rotation in the next two weeks. Stash now!

With Pablo Lopez (shoulder), David Festa (shoulder), and Simeon Woods Richardson (illness) all on the injured list in Minnesota, Abel may only need a handful more starts at Triple-A to prove he is ready to join the MLB roster. He is a top pitcher to stash in week 21 of the fantasy baseball season.

Dylan Beavers, OF, Baltimore Orioles
Current Level: MLB
Availability: 5% rostered
2025 AAA Stats: 94 G, .304/.420/.515, 14 2B, 18 HR, 23 SB
We will round things out with a prospect that recently earned the call to the big leagues. This past weekend, the Orioles opted to promote their outfield prospect, Dylan Beavers, from Triple-A Norfolk.
As the Orioles have been playoff contenders the last few seasons, it has been a little bit more excusable how much they've jerked around their top hitting prospects.
However, this year, given how much the team has struggled, it's pretty crazy how unwilling they've still been to give playing time opportunities in the majors to their top prospects. I've obviously been banging the drum about Samuel Basallo for months, but Beavers has been quietly really good this season.
At Triple-A this season, Beavers has a 152 WRC+ with 18 HRs and 22 SBs. He's also walking almost as often as he's striking out. Beavers realistically should've been up after the Orioles traded outfielders Cedric Mullins and Ramon Laureano at the Trade Deadline. Still, I suppose it's fair that they wanted two bites at the Rookie of the Year apple next season with him and Basallo.
Over the weekend, Beavers got the starting nod in both games in left field. In his debut on Saturday, Beavers went 1-for-5 with a double. Then on Sunday, the outfielder tallied another hit and scored two runs.
Given the ability he has shown to not only hit for power but showcase immense speed on the basepaths, he is worth adding in all 12-team category formats. He should continue to see every day opportunities in an Oriole lineup that has its eyes set on competing in 2026.
How about this for a 1st MLB hit?
