Fantasy Baseball Prospects Stash List: Ready to Make a Splash for Redraft Leagues (Week 7)

Joey's fantasy baseball prospects to stash list for Week 7 of 2025. His top MLB prospects and rookie sleepers to make fantasy impacts this year when called up.

Plenty of prospects will make their MLB debut this season. While it might be tough to pinpoint when prospects will be called up, stashing certain prospects on your roster right now could be a league-winning move for your fantasy team. Just look at those fantasy managers who held Paul Skenes and James Wood at the start of the 2024 season. 

In this article, we will look at five of the hottest prospects and analyze when they could be called up. Some of the top prospects like Roman Anthony and Jordan Lawlar won't be featured on this week's list because they were talked about exclusively on last week's edition. Both Anthony and Lawlar, though, should be stashed in every fantasy league right now. 

So, which other prospects should fantasy managers stash for Week 7 of the fantasy baseball season? Let's dive in and find out.

Bubba Chandler, SP, Pittsburgh Pirates

There has been a lot of talk about starting pitcher Bubba Chandler in recent weeks. The 22-year-old has dominated in the minors since the start of the 2024 season, and it's only a matter of time until the Pirates call up their top prospect. The right-hander finished with a 3.08 ERA and 148 strikeouts across 26 games (23 starts) at Double-A and Triple-A last year. 

Now, Chandler is off to a fantastic start at Triple-A Indianapolis to begin the 2025 campaign. Although he allowed a season-high three runs and four walks across 2 2/3 innings in his most recent outing on Wednesday, there's a good chance he will be promoted in the next few weeks.

MLB Pipeline's No. 12 overall prospect currently owns a 2.25 ERA, 0.93 WHIP, and 41 strikeouts across 28 innings pitched. 

Besides his most recent outing, Chandler has been lights out in Triple-A this season. He has allowed one run or fewer in five of seven outings, and opposing hitters are batting a mere .160 against him. While his rough start on Wednesday might have delayed his promotion by a week, the Pirates' top prospect should make his MLB debut sometime in May. 

As a result, Chandler should be stashed in every fantasy league before Week 7 begins. He has the potential to be a solid fantasy option right away, and his fastball/slider combo should help him put up solid numbers on the mound in Year 1.

With the Pirates currently sitting at 12-26 on the year, the right-hander should be promoted very soon. 

Cade Horton, SP, Chicago Cubs

Chicago Cubs' No. 2 prospect, Cade Horton, was on this list last week as a potential stash for later in the season. However, it appears that Horton will make his major league debut against the New York Mets this weekend. With Shota Imanaga (hamstring) landing on the 15-day injured list due to a hamstring strain, the Cubs are reportedly calling up their top pitching prospect to take his spot in the rotation.

The right-hander is much deserving of a promotion following his strong numbers at Triple-A to start the year. He has a 1.24 ERA and 33 strikeouts across his first six starts and has been untouchable on the mound. Horton is also coming off two strong performances in which he threw six innings of one-run ball with five strikeouts in back-to-back starts on April 29 and May 4. 

The biggest question now surrounding Horton is whether he is ready. The 23-year-old only pitched in 34 1/3 innings in 2024 before suffering a season-ending shoulder injury in late May. He also struggled a bit in his first few Triple-A starts last year.

He allowed 13 runs across 18 IP (7.50 ERA), and opposing hitters had a .254 batting average against him in those five starts. 

Still, Horton should be stashed in all 12-plus team leagues right now. He will make his MLB debut this weekend and should stay in Chicago's rotation until Imanaga returns. Even when the Cubs' star pitcher is back, MLB Pipeline's No. 46 overall prospect could stay in the rotation.

That will surely depend on how he looks in his first few major league starts. 

Either way, he's worth grabbing in most fantasy leagues. He has a solid fastball that averages in the mid-90s to go with an above-average slider. Therefore, Horton can potentially put up solid numbers in his rookie campaign. It'll be interesting to see how he fares in his first major league start on Saturday against a Mets offense that ranks 10th in runs per game (4.76). 

Jacob Misiorowski, SP, Milwaukee Brewers

There's not much left that pitcher Jacob Misiorowski has to prove down in the minors. The Brewers' No. 4 prospect continues to dominate at Triple-A Nashville and has only allowed one run over his last 17 innings. In those three starts, Misiorowski has thrown six scoreless innings with eight strikeouts (April 22), five shutout innings with nine strikeouts (April 27), and six innings of one-run ball (May 3).

The biggest thing likely keeping the Brewers from calling up Misiorowski right now is his lack of control. He issued four walks in his most recent outing on May 3 and has a 12.1% walk rate across his seven appearances this season.

However, the big right-hander has been much better at limiting walks in recent weeks, as he has allowed two walks or fewer in three of his last four starts. 

If Misiorowski continues to attack the strike zone, there's a strong chance that Milwaukee will call him up very soon. He has a plus-plus fastball that sits between 96-98 mph, and both his off-speed pitches (curveball and slider) can do just as much damage. So, it wouldn't be a surprise to see the 23-year-old dominate on the mound once he is promoted. 

Therefore, Misiorowski is someone to consider stashing in some leagues. He has looked impressive in Triple-A to start the season, outside of one start, and should be promoted at some point in 2025. Opposing hitters are batting just .158 against him across 35 2/3 innings in the early going. 

Andrew Painter, SP, Philadelphia Phillies 

Some fantasy managers might have forgotten just how good pitcher Andrew Painter is. He posted strong numbers in his first two minor league years in 2021 and 2022 before undergoing Tommy John surgery in July of 2023. After missing the entire 2023 and 2024 seasons due to an elbow injury, Painter is finally back on the mound. 

He made six starts in the Arizona Fall League this past November, where he finished with a 2.30 ERA and 18 strikeouts against 15 2/3 innings pitched. The right-hander is now continuing his build-up in the minors. He made four rehab starts with Single-A Clearwater to start the season and just made his first career Triple-A start on Thursday. 

In that outing, Painter threw three scoreless innings with one hit allowed, three walks, and five strikeouts. With the Phillies going all-in for a World Series title this year, it wouldn't be a surprise to see MLB Pipeline's No. 5 overall prospect be called up sometime in the next few months. Even though he has missed the past two years, there's a strong chance he makes his major league debut in 2025. 

As a result, Painter is a top prospect stash right now. He has the tools to be an elite starter in the majors right away, with his plus-plus fastball that sits at 98 mph. He's definitely worth stashing because he is the best pitching prospect in baseball, and he should be called up by the Phillies at some point this year. 

Moises Ballesteros, C/1B, Chicago Cubs 

Moises Ballesteros has easily been the best-hitting catcher at Triple-A this season. The 21-year-old is hitting .381 with four home runs, seven doubles, 18 RBI, and three stolen bases across 30 games with the Iowa Cubs. What's even more impressive is that Ballesteros has tallied at least one hit in 21 of the past 22 contests. 

It has been fun to watch Ballesteros tear it up offensively in the early going. Even though he is one of the youngest hitters in Triple-A, he continues to hit the ball hard. After breaking out with 19 home runs and 78 RBI in 124 games last season, the Venezuelan native is proving why he is MLB Pipeline's No. 63 overall prospect.

Therefore, he is someone to keep an eye on on your waiver wire. He isn't necessarily a must-stash at this point in the season because there really isn't anywhere for him to play with the Cubs. With Carson Kelly and Miguel Amaya occupying the catcher spots, Michael Busch as the primary first baseman, and Seiya Suzuki as the full-time designated hitter, it might be some time until Ballesteros is called up. 

However, there is a path where the 21-year-old makes his major league debut later this season. If an injury happens to Kelley, Amaya, or Busch, Ballesteros could be next on the pecking order. There's also a slim chance that the Cubs deal him away at the trade deadline for a superstar to help them win a championship.

Either way, he is someone to monitor over the next few months.
