Three top fantasy baseball prospects - Spencer Jones, Dylan Beavers, Robby Snelling - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
During the first half of the fantasy baseball season, managers saw several high-upside prospects earn the call to the big leagues. Many of these prospects made significant impacts such as Nick Kurtz of the Athletics and Jacob Misiorowski of the Brewers.
In this piece, we will look at two of the top hitters and a budding ace at Triple-A and determine if they should hold a spot on our roster.
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:29 G, .348/.426/.750, 6 2B, 13 HR, 14 SB, 34 SO, 16 BB
So is Aaron Judge going to be able to play the outfield this season? With the potential MVP dealing with a flexor strain, will the Yankees risk playing him in the outfield, where he could further injure himself throwing? If Judge is forced to DH the rest of the season, the Yankees will likely be looking for more production in the outfield. This opens up a playing time window for Spencer Jones.
Jones has slowed down a hair from his insane homer barrage from a couple of weeks ago, but he's still having an unbelievable season in the minors. After hitting 16 HRs with 10 SBs and a 186 WRC+ in 49 games at Double-A, he got the bump to Triple-A and improved.
He has 13 HRs and 13 SBs with a 195 WRC+ in 28 games at Triple-A. He's also improved on his biggest flaw by drastically reducing his K-rate. He's only striking out 24.2 percent of the time in Triple-A after striking out 33.7 percent of the time at Double-A.
July was hot, but Spencer Jones was hotter. 🔥
The No. 4 #Yankees prospect was tabbed by @MLB as July's International League Player of the Month, batting a league-best .419 with a league-high 11 home runs.

If Jones gets enough playing time, he might have the most power upside out of anyone in the minor leagues, especially playing half of his games in Yankee Stadium.

Dylan Beavers, OF, Baltimore Orioles
Current Level: AAA
Availability: 5% rostered
2025 AAA Stats: 87 G, .309/.423/.538, 14 2B, 18 HR, 22 SB, 62 BB, 66 SO
Samuel Basallo is not the only Orioles hitter in Triple-A who is on fire and banging on the door to the majors. Dylan Beavers should also be joining Basallo in the majors in the next couple of weeks.
There was some belief that the Orioles would call up Beavers right after trading away Ramon Laureano and Cedric Mullins at the deadline. However, they appear to want two bites at the Rookie of the Year PPI pick apple.
On the season, Beavers has 18 HRs and 22 SBs. He also has a 158 WRC+ and is walking nearly as much as he's striking out. Over the last month and a half, he's been one of the best hitters in the minors.
Dylan Beavers has been ON FIRE over the last six weeks...
Since 6/18: 146 PA, .325/.473/.702, 13 HR, 5 SB, 20.5% BB, 13.7% K
Nearly 1/3 (32.2%) of his PAs have resulted in a walk or home run during this timeframe.#Birdlandpic.twitter.com/s1I41MZlGu

Beavers is an exciting stash in all formats. His power and speed give him upside in category leagues, and his excellent plate approach gives him upside in points.

Robby Snelling, SP, Miami Marlins
Current Level: AAA
Availability: 5% rostered
2025 AAA Stats: 27 2/3 IP, 1.63 ERA, 0.98 WHIP, 34 SO, 5 BB
The move to Triple-A has seemingly made Snelling better, and his last two starts have been nothing but dominance. Coming off a career-best start to the end of July, where he struck out 11 batters across 6.2 innings, Snelling's next start consisted of six innings of one-run ball with seven strikeouts. Snelling has not allowed a walk in his last two starts.
When you look at Snelling, his strong frame probably does not scream premium athlete. But he is an exceptional athlete who was a four-star linebacker recruit, heading to LSU for both baseball and football. He spent little time focusing on baseball alone until being drafted. While 2023 was incredible, 2024 was a step in the wrong direction as Snelling posted a 6.01 ERA and a 5.50 FIP in 73 innings with the Padres’ Double-A affiliate before being traded to Miami for Tanner Scott. He did make improvements over the final two months of the season with Miami.
What Snelling has shown in 2025 looks back to the level of arm talent we saw in 2023, when he was named Baseball America’s Minor League Pitcher of the Year. His ERA is down to 3.26 on the year and is backed by a 2.84 xFIP and 3.09 FIP. The command has steadily improved, and Snelling is rocking a 21 percent strikeout minus walk rate.
The fastball used to sit in the low 90s with 16 inches of IVB from a 5’8” release height. Now, it is up to 95 mph on average with over 17 inches of IVB on average. Snelling gets 7-10 inches of arm-side movement with high spin rates for a four-seam and has shown the ability to miss bats.
His slider has some “slurvey” traits, having good depth and sweeping action. It's not quite a curveball, sitting in the low 80s, but it has a -5-inch IVB with 8-10 inches of horizontal. He is comfortable throwing it both in and out of the zone, getting whiffs and chasing. It runs away from left-handed hitters, but Snelling will also throw it to right-handers back foot on occasion.
The changeup has played quite well, generating 14 inches of fade on average while working around 88 mph. The added fastball velocity allows the changeup to play better now, given the separation between the pitches.
With a strike rate of 66.5 percent and a walk rate below 7 percent, Snelling looks the part of a high-end pitching prospect again. He should get a shot to pitch with the Marlins over the next few weeks.
Robby Snelling (@Marlins' No. 2 prospect) in four Triple-A @JaxShrimp starts after his 6 IP, 1 R, 7 K gem Friday night:
• 2.08 ERA
• 23 K in 21.2 IP
• 0.92 WHIP pic.twitter.com/KEPjnVv4AY— MLB Pipeline (@MLBPipeline) August 2, 2025
