The Stash List Week 11: Top 10 Pitching Prospects to Stash in 2025

Top 10 pitching prospects to stash in redraft league

John Villavicencio
Dynasty 6/8/2025

The Pitcher Edition of the Stash List highlights the 10 best pitching prospects likely to make an impact during the 2025 season.

Prospects are often thought of as only holding value in dynasty formats. However, knowing which prospects hold value for the current season can help set you apart in redraft leagues. Several have a 2025 ETA, and getting ahead of the curve on rostering these prospects is a key part of roster management. Last year, we saw more pitching prospects make their debut than ever before, and there is no reason we should expect to see anything change in 2025. Keep reading to find out the top ten pitchers you should stash in your redraft leagues.

 

Ground Rules

 

  • The Stash List is for your redraft leagues and does not consider impact beyond 2025.
  • Only current minor league players who are expected to make an impact this season are included.
  • Upside, proximity, health, and opportunity are all weighed for each player.
  • The focus is on 12-team leagues with standard categories.
  • Rankings and roster percentages will be updated weekly.
  • Stats will be updated weekly for all players through Thursday’s games.

Graduates/Call-Ups

 

Congratulations to all the families celebrating school promotions and graduations this time of year. It’s a significant achievement for the individual moving up and the people who supported them along the journey. Congrats, Class of 2025!

The following prospects got the call to the major leagues within the last week:

Mick Abel returned to the Phillies rotation, and we hold our breath to see if he sticks, since his presence covers Zack Wheeler’s paternity leave. On June 4, Abel’s velocity was registered as being down to further highlight that there were hot guns overestimating velocity and extension in his debut. He went 5.1 innings with only three hits and an amazing zero walks. His strikeout rate was low again, and he only generated five whiffs. Given Aaron Nola’s extended IL stint, Abel has an additional pathway to a starter spot.

Mike Burrows gave up 11 hard hits over 5.1 innings, but escaped without allowing any runs or walks to earn his first major league victory. He mixed in a 95 mph four-seamer with 18 inches of induced vertical break, a changeup with 13 inches of armside break, and a sharp slider with three inches of break. Burrows appears locked into a rotation spot with a two-start week ahead.

Since many pitchers below will be on the stash list for the foreseeable future, let’s dig deeper into a different part of their profile each week. This week will be a shorter summary of each prospect with game film for you to review.

Top 10 Pitching Prospects to Stash

 

1. Bubba Chandler, RHP, Pittsburgh Pirates

2025 AAA Stat line: 50.2 IP | 2.49 ERA | 33.5 K% | 10.5 BB%

2024 MiLB Stat line: 119.2 IP | 3.08 ERA | 30.9 K% | 8.6 BB%

 

Two innings? He only pitched two innings! The short start must be an indication that Roy Bubba Chandler is being prepped for a major league debut in the next week, right? It turns out that defensive gaffes and being hit around led to a long 28-pitch first inning for Chandler against the Memphis Redbirds on June 5. In addition, the weather caused a long delay to the game and forced the early pitching change.

When he was out there, half of Chandler’s balls in play were hit hard. The changeup provided mixed results with its 16.5 inches of arm side break. The changeup had a 44% whiff rate on the day as well as a .500 average against it. His fastball velocity was solid at 97 mph and touching a high 99 mph range. Given the low pitch count, it’s difficult to apply too much from the outing to future games. Yet, we have not seen ace-like consistency from Chandler in 2025 more than two consecutive games. He will continue to build upon his strong fastball, changeup, and slider combination to empower the Pirates organization to give him a chance over Mike Burrows and Braxton Ashcraft.

 

2. Logan Henderson, RHP, Milwaukee Brewers

2025 AAA Stat line: 33.0 IP | 2.18 ERA | 34.6 K% | 9.4 BB%

2025 MLB Stat line: 21.0 IP | 1.71 ERA | 35.8 K% | 7.4 BB%

 

In a shorter appearance on June 1, the Milwaukee Brewers signaled that Logan Henderson is a candidate for a call-up in the near future. He threw a stellar 70% of his 57 pitches for strikes against Indianapolis. He also threw a much higher rate of fastballs, about ten percentage points more. The four-seamer had about an inch less vertical movement than his season average, but he still managed four whiffs and a .270 xWOBA. Even with the reduced use of his supporting pitches, Henderson worked a fairly clean three innings with two hits, one walk, and four strikeouts.

Having focused on the fastball above, we will revisit any developments in his supporting pitches as mentioned in the previous stash list article. His velocity was down in the game, most notably two mph on the cutter. The spin, movement, and release points were virtually identical to his typical pattern. About the only difference was the whiff rate on his second-best pitch, the changeup. He didn’t get a single batter to chase the pitch out of the zone, signaling a likely team-wide strategy. Given that his fastball velocity is mediocre, he will need to have his changeup performing at its best to keep hitters from sitting on the four-seamer.

 

3.  Joe Boyle, RHP, Tampa Bay Rays

2025 AAA Stat line: 48.0 IP | 1.69 ERA | 29.6 K% | 11.1 BB%

2025 MLB Stat line: 5.0 IP | 0.00 ERA | 38.9 K% | 11.1 BB%

 

Disaster was avoided after a short Memorial Day start, as Joe Boyle returned to the mound on June 1 to finish five scoreless innings. The fastball velocity was back to normal, and he had the feel on all of his pitches. The 6’8″ righty got four whiffs on the slider and splitter, and five more on the fastball. Boyle even demonstrated solid control with a 53% zone rate and 64% of his 71 pitches earning a strike. Bolstering his renewed command, his only walk came on a few pitches in the shadow zone, being called a ball. After a brief injury scare, Boyle is a solid stash for his strikeout upside.

Boyle is one of the top strikeout pitchers in the minor leagues this season, but fantasy managers are keen to compare any new stats to his previous performance. As for overall strike-throwing ability, his zone rate is slightly up in Triple-A from 2024, going from 45.1% to 45.4%. When you scan over his strike rate, the progress is much more pronounced, going from 58% strikes to 63%. Zooming in on strikes, Boyle is getting a top-5 level 18.5% swing-and-miss rate on all of his pitches. Coupling the increased swinging strikes, he has reduced the walks from 18.9% to 11.1%. Not only is Boyle keeping runners off the bases with fewer free passes and more strikeouts, hitters are putting the ball on the ground more often when they do make contact.

Although the mood was very pessimistic on Boyle last week, he is a solid pitcher with the improved command and harnessed velocity. The Tampa Bay organization has done an amazing job with his reform. Now, they only need to clear the runway for his promotion.

 

4. Andrew Painter, RHP, Philadelphia Phillies

2025 A+, AAA Stat line: 32.1 IP | 3.90 ERA | 26.8 K% | 8.7 BB%

2024 MiLB Stat line: 15.2 IP | 2.30 ERA | 30.5 K% | 6.7 BB%

 

Andrew Painter is healthy, maintaining velocity gains, and gradually building up his pitch count. There have not been any major updates about his potential call-up, but the Phillies’ rotation has taken a few hits to their healthy status over the last week. Zack Wheeler, Aaron Nola, and Jesus Luzardo have each spent time away from the team or suffered from poor performances. Painter is supposedly on the rise, ready to join Mick Abel on the staff to help push the Phillies into the playoffs. Painter is now averaging above 80 pitches per game, giving him enough endurance to go at least five innings. With his awesome stuff and four-pitch mix, he is likely to be a productive member of the staff in August when the Phillies make their playoff push.

On the other hand, Painter is only showing flashes of dominance. His K-BB% has been a rollercoaster ride up to 28.6%, then down to 4.8%, before peaking at 35% and landing back in a valley at 4.8%. He finished this game throwing 69% of his 85 pitches for strikes, producing five strikeouts on 13 whiffs. Yet, he gave up six hits, four earned runs, and four walks in his four innings of work. In addition, left-handed batters are mashing on him with a .947 OPS against, including three extra base hits in this game. He left a cutter up to Brooks Baldwin for a solo blast and left a curveball up to Andre Lipscius for a two-run blast. There is something about the movement on his pitches that lefties like, so he will need to improve the changeup and cutter to keep the ball away from their bat paths. This handedness-splits difference is lightweight concerning, meaning you should be cognizant of its presence, but not overly concern yourself with the numbers blocking his path to the major leagues. If this is still present in July, then perhaps we may need an offseason to help improve pitch mix and movement.

 

5. Jacob Misiorowski, RHP, Milwaukee Brewers

2025 AAA Stat line: 58.1 IP | 2.31 ERA | 31.1 K% | 11.9 BB%

2024 MiLB Stat line: 113.0 IP | 3.03 ERA | 34.2 K% | 10.0 BB%

 

Don’t you just love it when you totally nail a prediction? And I quote from last week…”In the big picture, Jacob Misiorowski has shaken off enough of the control issues to quiet the reliever talk spoken about his name.”  Misiorowski, the soon-to-be reliever, proceeded to walk six batters and hit one batter, completely melting down in the third inning of his May 31 start against the Indianapolis Indians. Reliever! In that inning, the righty “reliever” gave up four walks with a hit by pitch chucked in. The 38% zone rate on his 65 pitches was weighed down heavily by the four-seamer, also landing in the zone only 38% of the time. Sounds like reliever material, right? In the game, he had a 49% strike rate, over 14% points less than his season average of 63% strike rate. Reliever!

In all seriousness, this game represents the absolute worst of what could happen in his games when Misiorowski loses the feel for his fastball. Comparing this game to the season averages on the fastball, he had a similar release point, spin, horizontal movement, and velocity. His induced vertical break on the four-seamer was the only low reading, rising about an inch less than what he usually gets. In his 28-pitch third inning, the ball was sailing on him, and once the hitters recognized his loss of control, they didn’t need to swing at any of the fast stuff. On the positive side, he is still getting whiffs on his pitches, 11 on the night. The only way to ease nerves around Misiorowski’s starter appeal is to see him pitch a solid game with minimal walks, something he has not done in a few starts. Despite all the negative energy, Misiorowski still has the lowest walk rate of his career while maintaining a 30%+ strikeout rate and inducing a lot of weak contact on the ground. The only direction is up for this “reliever” turned starter!

 

6. Chase Burns RHP, Cincinnati Reds

2025 AA Stat line: 46.2 IP | 1.93 ERA | 40.1 K% | 5.2 BB% 

2024 NCAA Stat line: 100.0 IP | 2.70 ERA | 48.8 K% | 7.7 BB%

 

On May 31, Chase Burns continued his dominant stretch after completing six innings for the first time in his professional career. Burns brings a competitive edge to the mound, often pumping his fist after inning-ending strikeouts. He found himself down in the count a few times, only to fight back to force a weak-hit ball in play. On this day, he had to find a new way to succeed with only four strikeouts on 16 whiffs. This season, for minor league pitchers with more than five games started, he trails Trey Yesavage (20.9%), Joe Boyle (19.2%), and Juaron Watts-Brown (18.5%) for the lead in swinging-strike rate at 18.2%. He had to let his defense do more of the work with a higher number of balls in play. On the year, his ground-ball rate is a touch above the fly-ball rate at 41.6% to 37.6%. As the weather heats, we hope that he can manage to keep that rate in favor of the ground balls.

His area of growth will be to work on pitches to play off the fastball. Burns locates his fastball in the lower third of the plate, a recipe for disaster no matter the velocity. He gave up eight fly balls in this game, either off a fastball or a hanging slider. His comeback will likely be to place a changeup or slider in the same part of the zone to add in that horizontal break. He could also develop a cutter to help keep the ball away from the bat. Either way, Burns is succeeding, and a promotion is imminent. The Reds have a few stumbling Triple-A prospects, Rhett Lowder and Chase Petty, who could give way to a rapid rise from Burns. There is a period around the All-Star Break in July when Burns could be a candidate for a spot start.

 

7. Cade Cavalli, RHP, Washington Nationals

2025 AAA Stat line: 32.1 IP | 3.34 ERA | 27.2 K% | 9.6 BB% 

2024 MiLB Stat line: 8.1 IP | 2.16 ERA | 41.9 K% | 16.2 BB%

 

Cade Cavalli is a post-hype prospect stash that is returning from a 2023 Tommy John surgery. He followed up a standout performance with a mediocre outing against Worcester, one of the toughest lineups in Triple-A. He gave up five hits, three hard hits, three walks, and two earned runs. Cavalli reached his pitch limit for the day in the fifth, even though he induced a double play and left with no one on base. The newsworthy item is that his velocity and movement were both down a tick. Part of why I am buying into his resurgence is that his fastball has a potential velocity jump as he gains more confidence in the health of his arm. If the velocity continues to fall or stay too low, then we may need to rescind all recommendations to stash.

So far, Cavalli is showing a four-pitch mix, with the changeup and curveball leading the way. These two pitches have similar release points, but are bending to polar opposite sides of the zone. The exciting part of his mix is that he is currently governing his velocity to maintain arm health. It will be intriguing to see if he can gain greater separation between the four-seamer and the sinker to harness more swing and miss out of hitters. Cavalli is also generating a healthy 60% rate on ground balls through thirty innings. All eyes are on the roster spot held down by Trevor Williams. Williams is the poorest-performing righty with options left in the rotation. I would imagine that Cavalli needs to hit 85 pitches in a game before being considered a viable call-up. He is likely two weeks away from that range, making him a strong stash now before people catch wind of his performance.

 

8. Ian Seymour, LHP, Tampa Bay Rays

2025 AAA Stat line: 61.0 IP | 2.95 ERA | 32.7 K% | 5.8 BB% 

2024 MiLB Stat line: 145.0 IP | 2.35 ERA | 28.1 K% | 7.1 BB%

 

Is Ian Seymour a worthwhile stash? Some say heck no, and some demand his call-up. Where you stand completely hinges on whether you buy into a low-90s fastball and a cast of secondaries having presence in the Major Leagues. I recently compared him to Little Mac from Mike Tyson’s Punch-Out since people love underdogs. We are tired of watching him beat up on Glass Joe and desperately want to see how he does against Piston Honda or Bald Bull. The undisputed fact is that Seymour has displayed strikeout savvy with a 32.7% strikeout rate over 61 innings, continually making him one of the top strikeout pitchers in all of the minor leagues. His season strike rate is at 64.6% with a tick up on the swinging-strike rate to 16.4%. On top of all that, he has reduced the walk rate to under 6%, giving him one of the best K-BB% in the entire minor leagues. The only thing he doesn’t do is throw the ball hard. Or does he?

It’s hard to measure the force of a pitcher from afar, but Seymour is averaging over 17 inches of induced vertical break, sometimes getting that fastball up 21 inches. He is achieving this ride on his fastball from a lower attack angle with a deceptive arm action that adds a touch of bewilderment for hitters reading his pitches. In addition, hitters are not squaring up this pitch with a .163 average against and a .286 xWOBA. They just aren’t doing much damage on what is easily considered a below-average major league fastball. He probably won’t develop much more velocity like a similar lefty prospect with a deceptive delivery, Gage Jump, but he holds a 35% whiff rate on a pitch that he uses 39% of the time. The fact that he mirrors the release point of his four-seamer to the cutter and the sweeper boosts the fastball’s performance. In the end, we just want Seymour to level up to get a match-up with Don Flamenco or even settle for King Hippo.

For the fourth time this season, on June 3 against Jacksonville, Seymour pitched a clean slate with zero walks. He only generated 10 whiffs and a meager six strikeouts, but went six innings for the second time in 2025. The things to watch will be how his sweeper and cutter improve over time, since they tend to be his worst-performing pitches. Yet, their ineffectiveness helps the performance of his fastball.

 

9. Michael McGreevy, RHP, St. Louis Cardinals

2025 AAA Stat line: 55.0 IP | 2.78 ERA | 25.9 K% | 5.4 BB%

2025 MLB Stat line: 5.1 IP | 0.00 ERA | 25.0 K% | 5.0 BB%

 

Can the St. Louis Cardinals catch the Cubs in the Central Division with a veteran rotation and average offense? Your response probably falls upon the proximity of your address to Illinois or Missouri, and how you feel about Erick Fedde, Miles Mikolas, and Andre Pallante being major components for this team in August. The good news is that the Cardinals have plenty of reinforcements at the Triple-A level ready for action if someone in the back of the rotation falters. I give the edge here to Michael McGreevy due to his repeated demonstrations of success at the major league level, both in 2025 and 2024. He does not possess the strikeout upside we normally crave, peaking at a 25.9% strikeout rate this season, but he has maintained a sub-6.5% walk rate since his college days at UC Santa Barbara. He also has kept a solid ground-ball rate above 50% while maintaining a hard-hit rate around his previous rates.

McGreevy is likely not as smooth as MacGyver, but he has many tricks in his tool belt. McGreevy throws five pitches plus a sprinkling of curveballs. The sweeper is his standout pitch with 14 inches of break and a 39% whiff rate. In his latest outing against Indianapolis on June 3, he strangely managed only one whiff and three called strikes. He had more success throwing his sinker and four-seamer at the same rate as the sweeper, generating five whiffs on those two pitches. Although he didn’t go long in this start, it was due to his performance. He threw 64% of his 75 pitches for strikes, earning four strikeouts and one walk on the day. It is possible that his reduced usage is to keep him fresh for any potential call-up in the next week. Nevertheless, McGreevy ended his night on a 93 mph sinker at the top of the zone for a called strike three. Word on the street is that he will be recalled for a spot start on Sunday and could get a few starts. Check your waiver wire for his availability.

 

10. Quinn Mathews, LHP, St. Louis Cardinals

2025 AAA Stat line: 23.0 IP | 3.52 ERA | 23.3 K% | 17.5 BB%

2025 MLB Stat line: 143.1 IP | 2.76 ERA | 35.4 K% | 8.6 BB%

 

Welcome back to the stash list, Quinn Mathews! After shoulder soreness shelved him for a month, Mathews has made four rehab starts, with the most recent two appearances for Triple-A Memphis. On June 6 against Indianapolis, he threw over 60 pitches in his five innings of work. Mathews generated 11 whiffs on his four-pitch mix that produced six strikeouts and zero walks. Mathews gave up five hits, but didn’t face much trouble besides back-to-back singles at the top of the fourth inning. Although he is not on the 40-man roster, each clean Mathews appearance raises the probability that St. Louis can extend him a call-up this summer. He is behind McGreevy in the pecking order and likely needs to reach out at least 85 pitches to be considered close to healthy.

Mathews is matching most of his current pitch metrics from 2025 and 2024. He averaged 94.9 mph in his most recent start while averaging 94.4 mph on the four-seamer last season. His extension on pitches ranged from 6.3-6.4 feet for this start, which mirrors both of the last two seasons. One notable change from year to year is that his release height is slightly up, meaning that he is either throwing with a higher arm angle or maybe putting a touch less finish on his pitches. In terms of performance, the fastball is lagging behind all of his other pitches with a single-digit whiff rate after being 26.4% in 2024. Although the velocity is up, their vertical and horizontal break are a few inches off of their 2024 marks. He is attempting to bring the slider into use more often, which would be a good way to counter hitters sitting on the fastball since those two pitches have similar release points.
