Kevin Luo's top hitter fantasy baseball prospects to stash for Week 22 (2025). His MLB prospects to pick up and stash on your bench and N/A spots in redraft leagues.
We had an electric week of hitting prospect call-ups this week. As expected, after the August 15th deadline, when teams could call up prospects and retain their rookie eligibility for next week, there are now several exciting new major leaguers.
Samuel Basallo, Dylan Beavers, Carson Williams, and Jhostynxon Garcia all got the call this past week (along with Bubba Chandler on the pitching side). There are still several top prospects who could make their debut this season and help us in fantasy.
Let's look at a few top prospects to stash for Week 22 of the fantasy baseball season.

JJ Wetherholt, SS, St. Louis Cardinals
I took JJ Wetherholt off my prospects to stash article last week after Cardinals president of baseball operations John Mozeliak poured a bit of cold water on the possibility of Wetherholt getting a call this season.
However, the Cardinals are in a situation right now where they should be looking to call up Wetherholt for a late-season playoff push. They're currently four games out of the final Wild Card spot, and promoting their top prospect might give the team the jolt it needs to sneak into the playoffs.
Wetherholt has been phenomenal in his first full season of professional baseball. After being drafted seventh overall last season, he's made light work of Double-A and Triple-A pitching. Between the two levels, he has a 153 wRC+ with almost as many walks as strikeouts.
One impressive aspect of his game is how he's hitting for more power since getting the bump to Triple-A. He has nine of his 16 HRs on the season in 124 PA at Triple-A.
JJ Wetherholt has hit the ground running in AAA with 9 HR in his first 25 games. His ability to make consistently hard contact while laying off bad pitches makes him a dangerous threat.

Wetherholt should provide a very solid all-around fantasy profile if he gets the call to the majors this season.
Sal Stewart, 3B/2B, Cincinnati Reds
The Reds are currently a half-game out of a Wild Card spot in the NL, and Sal Stewart CAN HELP THEM NOW! Do I need to say more as to why they should call him up?
Stewart is having an excellent year in the minors between Double-A and Triple-A. The dude just hits. He has a 150 wRC+ between the two levels with a 15.5 percent K rate. He has also improved his BB rate since getting the bump to Triple-A from 8.2 percent to 11.3 percent and his ISO from .167 to .315.
He has 17 HRs and 16 SBs on the season to go along with his very advanced hit tool.

You're going to have to ignore what he's done in Los Angeles with this comp, but Stewart kind of reminds me of early career Anthony Rendon. I also see some Alex Bregman in the non-bouncy ball seasons. Either way, he should provide a solid all-around profile, and his power will get boosted playing half of his games in Cincinnati.
Spencer Jones, OF, New York Yankees
So, Spencer Jones has come back down to earth a bit after his first few weeks at Triple-A, when he was homering almost every night. I joked that MLB columnist/insider Jon Heyman cursed him a bit by saying the Yankees should only trade him for Paul Skenes at the deadline.
Even with a slow few weeks, his numbers on the season are still ridiculous. Between Double-A and Triple-A, he has a 169 wRC+ with 31 HRs and 25 SBs in only 390 PA.

Along with his prodigious power, he also has a very obvious flaw. He has a ton of swings and misses in his game. He is striking out 31.3 percent of the time after striking out 36.8 percent of the time in Double-A last season. He also has a 61.9 percent contact rate, which is awful, although it has gotten better since getting promoted to Triple-A at 65.4 percent.
Yankees fans -- put on your earmuffs, but Jones could have some Texas Rangers Joey Gallo seasons. He has incredible power, and the batting average will be bad, but he will have value in fantasy, especially in OBP leagues.
Kristian Campbell, 2B/SS/OF, Boston Red Sox
Are the Red Sox going to have David Hamilton play a majority of the time at second base the rest of the season? I can't imagine that will be the case. Romy Gonzalez and Nate Eaton will probably get a good amount of playing time as well, but I don't know why they haven't brought Kristian Campbell back to the majors.
Campbell isn't the best defensive second baseman, but his bat should be somewhere in the Red Sox's current and future plans. The Red Sox need to take a page out of the Cubs' playbook with how they handled Matt Shaw. They sent him down, let him get his confidence up a bit, and now he's back up in the majors and playing well.
Campbell hasn't set the world on fire at Triple-A, but he's playing pretty well and should be making his way back to Boston soon. He has a 121 wRC+ with six HRs in Triple-A over the last two months.
The shine has assuredly dimmed a bit on Campbell, but he was on a meteoric rise last season into May of this season. He came into the season as one of the best prospects in baseball after having a 178 wRC+ across three levels, and he had a 149 wRC+ in the majors this season through April.
Campbell still has the potential to be the hitter we saw last season. If he gets the call back to Boston, we've seen what impact he can make in a small sample.
Jordan Lawlar, SS/3B, Arizona Diamondbacks
Jordan Lawlar is back in Triple-A after recovering from his hamstring injury, so the clock is ticking again for his return to the majors. With the Diamondbacks trading Eugenio Suarez, they surely had plans to bring Lawlar back to Arizona before the end of the season.
Blaze Alexander has actually been pretty solid for the Diamondbacks over the last few weeks since Suarez's trade, but Lawlar is their top prospect, and Alexander suits a super utility role better for them in the future.
Lawlar hit his 11th homer earlier this week and his first since returning from the IL. He also has 19 SBs and a 134 wRC+ so far this season in Triple-A.

I know -- Lawlar has almost been impossibly bad in his two stints in the majors so far -- with a negative wRC+ both times. However, both of those were in very small sample sizes with sporadic playing time. I still think he has five categories upside if given a little bit of playing time runway.
