Fantasy Baseball Prospect Report – Wetherholt Call-Up Imminent?

After the Major League Baseball trade deadline, it’s not just the big league rosters of many teams that are adjusted. Far more prospects are traded than big leaguers, which often creates opportunities at higher levels for players deserving of a promotion. Now is a great time to take stock of those changes.

Many teams that are out of the playoffs are going to start moving prospects around and calling up prospects to get some playing time in 2025. Disappointing teams like the Tampa Bay Rays, the Atlanta Braves, and the Baltimore Orioles have some of the league’s top prospects lingering. Hopefully, their uneven seasons mean we see some of those faces on the move soon.

As players graduate to the Major Leagues, new names will always take their place as the season goes along, but for now, some prospects are just starting to get their first shots. All stats are as of games completed on August 3rd. Today’s piece will focus on the most relevant prospect news from around the minor leagues, focusing on the biggest names in the 2025 Top 100 list and who has been moved up closer to the big leagues lately.

Now, with the dust settled from the trade deadline, let’s take a look at some of the Top 100 prospects on the move in minor league ball right now.

Fantasy Baseball Prospect Report

Alfonisn Rosario, CLE, OF

The Guardians’ sixth-round pick from 2023 is heading to AA at 21 years old after performing well for just over half a season in A ball for Lake County. He was hitting .268/.362/.490 with 16 homers and 11 steals as a full-time outfielder. He should start in the outfield for Akron this week.

Colt Emerson, SEA, SS

Top Mariners’ prospect Colt Emerson will move from A-Affiliate Everett to Double-A Arkansas this week. In 90 games at High-A, Emerson, who just turned 20 years old, hit .281/.388/.453 with 11 homers and six steals. He is the shortstop of the future for Seattle.

Payton Tolle, BOS, SP

One of the Boston Red Sox top pitching prospects will move from AA to AAA this week, not too long after he was moved from High-A to AA. In Double-A, Tolle pitched 27 innings, with a 1.67 ERA and a 0.74 WHIP with 37 strikeouts. He pitched six times for Portland as a starter, and that is likely his future in the majors, but he is just 22 years old.

Luis Pena, MIL, SS/3B

Speedster Luis Pena is just 18 years old and is getting a bump up from Low-A Carolina to High-A Wisconsin. He was hitting .308/.375/.469 with six homers and a whopping 41 stolen bases and is splitting time between third base and shortstop alongside the next player on this list. The duo got the call to move up together in early August.

Jesus Made, MIL, SS/3B

Jesus Made is also 18 years old and plays on the left side of the infield next to Luis Pena every day. They often split the third base and shortstop positions, and should continue to do that as they move to High-A together. Made has a slightly less impressive slash line at .267/.373/.388, but he has also stolen 40 bases in 83 games. These two might be playing next to each other in the Milwaukee system for the next 15 years.

JJ Wetherholt, STL, SS

JJ Wetherholt was promoted to AAA Memphis before the MLB trade deadline, but he has been playing very well since that July promotion. Since the move, he is hitting .344/.425/.754 with six home runs in 16 games. Overall, he is hitting .310/.425/.528 in the minors this year.

But perhaps most interesting is that Wetherholt made his first start at third base this week. With Nolan Arenado unhappy and going on the IL with a shoulder injury, the Cardinals might be priming Wetherholt to take over the hot corner.

C.J. Kayfus, CLE, 1B

Power-hitting first baseman C.J. Kayfus got the call-up to the big leagues to play for Cleveland after the trade deadline. He was DH and outfield for his first two starts, but should get a number of starts at first base for the rest of the season. Kayfus is just 23 years old, but still should get looks at first base along with Kyle Manzardo and Carlos Santana.

Samuel Basallo, BAL, C/DH

With the Baltimore Orioles going with a full youth movement after trading a whole host of veterans at the trade deadline, Samuel Basallo got a vote of confidence from GM Mike Elias. Elias said it would be beneficial for Basallo to make the Major Leagues this season, which bodes well for a call-up soon. Just 20 years old, Basallo is an offensive force with 20 home runs in 66 games in AAA this season.

Dylan Beavers, BAL, OF

Outfielder Dylan Beavers got the same treatment as Samuel Basallo, as Mike Elias said there is a good chance Beavers sees the Major Leagues at some point before the end of the season. Beavers is almost 24 years old and was a first-round pick in 2022, so the case for him to make the majors is clear. In AAA this season, Beavers has 16 home runs and 22 stolen bases in 85 games.

Leo De Vries, ATH, SS

In a somewhat shocking move, one of the Padres’ top prospects, Leo De Vries, was included in part of the deal that brought Mason Miller and JP Sears to San Diego. Now, with the Athletics, we will have to see how they handle one of the youngest—and most talented—prospects in baseball. He is making quite a good first impression in High-A with the Athletics. He is hitting .333/.368/.533 in his first 20 plate appearances with the new team.

Mick Abel, MIN, SP

One of Philadelphia’s top pitching prospects, Mick Abel, was traded to Minnesota as part of the deal that sent Jhoan Duran to the Phillies to be their new closer. Abel appears to be staying in AAA for now, especially since he has struggled in the majors this year. But with the Twins selling off players at the deadline, and with them starting guys like Jose Urena and Travis Adams now, don’t be surprised if we see Abel pitch for the Twins this season.
