The Stash List Week 12: Top 10 Pitching Prospects to Stash in 2025

Top 10 pitching prospects to stash in redraft league

John Villavicencio
Dynasty 6/14/2025

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.

 

The Stash List

 

Graduates/Call-Ups

 

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

The new darling of everyone who hasn’t been following his Triple-A action, Jacob Misiorowski, did his 100 mph fastball routine against the Cardinals in his Major League debut. Folks are talking positively about the fastball movement now, so let’s see if he can throw it in the zone better than 50% of the time. He hit the zone 53% of the time and generated 60% strikes in this game. He is a pitcher who will benefit from the challenge system since he can sometimes get squeezed on the shadows of the zone, like in this game, where he issued four walks. He only got five strikeouts, but he didn’t allow any hits, continuing a strong pattern of being all or nothing. The only mishap came when he rolled his ankle at the start of the 6th inning and came out of the game with lower leg cramping. Hopefully, he doesn’t suffer any setbacks because he has a juicy two-step coming up. He would face the Cubs next week, followed by home starts against Pittsburgh and Colorado. You will have to pony up a lot of FAAB budget.

Michael McGreevy was recalled for a tough assignment against the Dodgers. He battled with his six-pitch mix through six innings despite giving up four earned runs on 10 hard-hit balls. He finished the sixth inning with two strikeouts after generating ten whiffs on the day.

Brandon Walter earned a spot in a six-man Astros’ rotation after a quality start against Cleveland last week. He uses a five-pitch mix with the cutter being the primary fastball at 88 mph.

Ian Seymour earned his first Major League win in his first appearance out of the bullpen. He “blew” a 93 mph fastball past Romy González to earn his first career strikeout, but later settled into 90 mph during his two innings of work. It’s unclear if he will be tapped for a start, but Seymour appears ready for any challenge.

 

Top 10 Pitching Prospects to Stash

 

1. Bubba Chandler, RHP, Pittsburgh Pirates

2025 AAA Stat line: 51.1 IP | 2.63 ERA | 32.6 K% | 12.1 BB%

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

 

Two-thirds of an inning? He only pitched two-thirds of an inning! If we apply positive spin to this debacle, perhaps the Pirates wouldn’t want to tax him ahead of any debut after he reached 31 pitches to retire two batters, right? Right???!!! The 26% zone rate on his pitches tells you all you need to know about what kind of day it was for Chandler. He almost had more mound visits, 4, than batters faced, 6. None of his arsenal was working, and the St. Paul hitters seemed content to take the free passes. It is quite concerning that, for the second week in a row, Chandler has failed to live up to the expectations of the supposed number one pitching prospect in baseball, not named Chase Burns.

Fortunately for dynasty managers, Chandler did not appear to suffer an injury or exacerbate any mechanical issues. Sometimes touching 102 mph, Chandler displayed his usual velocity at 99 mph. In addition, his release points and extension in this game were all similar to his season marks. Like you, I’ll be eagerly checking news feeds for any updates on Chandler to confirm that there is no injury present and to see how the team spins this poor outing.

 

2. Logan Henderson, RHP, Milwaukee Brewers

2025 AAA Stat line: 38.0 IP | 1.89 ERA | 35.0 K% | 9.1 BB%

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

 

In a surprising move, the Milwaukee Brewers have jumped Misiorowski above Logan Henderson despite his recent Major League success. Henderson is already on the 40-man roster, last pitched on the same day as Misiorowski, and is only a dozen or so innings behind Misiorowski’s 2024 total. The most likely outcome is that Misiorowski’s promotion is for relief support, and that Henderson still has a decent shot at becoming a starter. Quinn Priester is the most susceptible pitcher in the rotation, with a 4.3% K-BB%, a 51% zone rate, and is slightly outperforming his xERA. Aaron Civale was moved to the bullpen to make room for Misiorowski, so it isn’t out of the question for Henderson to swap with Misiorowski in the near term.

Logan Henderson would have the lowest range of arm angles if on the Brewers at 31-36 degrees. He is in a virtual tie with Aaron Civale for the fastball with the biggest induced vertical break around 17-18 inches. Yet, Henderson has about a foot lower release height and six inches greater extension than Civale. Henderson’s changeup has the most horizontal movement in the rotation, bending to the arm-side with almost 19 inches of break. He is also the only pitcher on the staff with a fastball-changeup mix that has nearly a 30% whiff rate on each pitch type.

In his June 7 game, Henderson only threw 70 pitches over five scoreless innings to finish with six strikeouts on 14 whiffs. The perception is that Misiorowski’s fastball velocity would play better in the Major Leagues, but Henderson is the one who continually demonstrates swing-and-miss capabilities with its 29% whiff rate. Look for Henderson to get the next available starter spot, especially if Priester falters with his command or Misiorowski comes up short in his debut.

 

3.  Joe Boyle, RHP, Tampa Bay Rays

2025 AAA Stat line: 54.0 IP | 1.50 ERA | 30.5 K% | 10.5 BB%

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

 

As the swinging strike leader in Triple-A, Joe Boyle can help his cause by landing his secondary pitches in the zone more often. (Quiz: Guess who is second in Triple-A?) In his most recent start against Jacksonville on June 7, Boyle dropped the slider in the zone 63% and the splitter 56% of the time. Overall, he had a stellar 71% strike rate over 78 pitches and six innings. After a 2024 season with the Athletics, where he averaged 56% strikes, he has improved to a 63% strike rate between the Minor Leagues and Major Leagues.

That 28% bump in swinging strikes is likely due to a fairly major arsenal change for Boyle. He has ditched the sweeper in favor of a split-fingered fastball. The splitter moves at 93 mph and 16 inches of arm-side break, while plummeting 28 inches. Signalling a high level of confidence in this pitch, it has not caused any walks while generating a 47% strikeout rate. Collapsing his arsenal to a three-pitch mix has allowed him to mirror their release points. He now operates in a narrower velocity range with three pitches that are rising, tailing, and dropping to all parts of the zone. Therefore, his main weakness is and will continue to be locating the 98 mph four-seam fastball inside the shadows of the strike zone. The fastball has a 16.7% walk rate with a .304 xWOBA against. By putting his energy into commanding the pitch with a one-tick drop in velocity, he is actually improving all facets of his game.

With Ian Seymour up with the Rays (Ian Seymour is the second leading AAA pitcher in swinging strikes at the time of this write-up), Boyle shouldn’t be too far behind. After reaching 100 innings in 2024, Boyle has a legitimate shot to exceed 120 innings this year. This ceiling somewhat dampens any enthusiasm for his call-up in 2025 because he is almost halfway there. If he were called up next week, then he would have about 16-18 starts ahead of him. When he does return to the Rays, he may have to be near perfect like on June 7 to sniff the sixth inning and beyond. Nevertheless, you are stashing him because the 30% strikeout rate would propel any fantasy team to the top in that category.

 

4. Andrew Painter, RHP, Philadelphia Phillies

2025 A, AAA Stat line: 37.1 IP | 4.82 ERA | 25.3 K% | 7.4 BB%

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

 

After one month of talking about the process and a gradual build-up, it’s time for a few big-name prospects on the stash list to show off their pedigree. Andrew Painter took a few steps back with another poor performance on June 10. Even without Roman Anthony or Marcelo Mayer, the Worcester Red Sox drilled nine hard-hit balls off of Painter, including two home runs. His historical batted ball profile shows that he does give up a lot of fly balls, around 40%, but the home-run-to-fly ball rate has skyrocketed to over 17% in the Minor Leagues this season. On this evening, he allowed 13 fly balls while extending the margin between his effectiveness against each handedness of hitters. Painter now suffers from a 1.039 OPS against left-handed batters as compared to a .594 OPS against righties. As an example of the poor performance, the ninth-place switch hitter with a lifetime .700 ops, Tyler McDonough, did not miss on a middle-middle cutter, and sent it out 367 feet to right field at 107 mph for a solo home run.

It is possible that his outcomes can be ignored due to a variety of factors, such as a lack of motivation or competitiveness, different baseballs, significantly different field conditions, or disruptive pitching advice, among other reasons. Yet, we cannot ignore sustained, inconsistent performances that Painter continues to have, especially when he demonstrates disturbing patterns such as the horrible splits. One good thing that one can take away from this evening is that he was resilient enough to finish out the game after giving up six earned runs, unlike Bubba Chandler, who didn’t overcome early adversity. Painter also has the benefit of playing for a playoff team that may need his services earlier than anticipated if Aaron Nola has more setbacks in his ankle and rib cage recovery.

Digging deeper into this game, Painter was throwing the ball differently than he had all season. All of his pitches were being thrown at a slightly higher release point, about 3-5% higher, likely due to suppressed extension. Looking at his pitch mix, his second-most-used pitch, the cutter, continues to be hit-or-miss. It was blasted for a .667 average and a .822 WOBA in this game, while also generating five whiffs. His cutter usually has six inches of glove-side break and a 25% whiff rate. Painter had been doing a great job of mirroring his release points, but his mechanics or something else caused him to be slightly off recently.

 

5. Chase Burns RHP, Cincinnati Reds

2025 AA/AAA Stat line: 59.0 IP | 1.83 ERA | 37.4 K% | 5.9 BB% 

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

 

The Cincinnati Reds are not holding back their 2024 first-round draft pick after promoting Chase Burns to Triple-A Louisville. His trajectory is now aligning with an aggressive Paul Skenes‘ path to the Major Leagues. Skenes completed over 100 innings in college during his draft year before building to over 70 pitches per start in Triple-A the following season. Similar to Skenes, Burns worked 100 innings in college during his draft year and is now throwing over 80 pitches per start entering his third Minor League level in 2025. The 6’3″ righty has built a foundation of success and earned the trust of his organization, building off of three consecutive college seasons with over 100 strikeouts.

The impetus for his promotion was likely known long before, but Burns was utterly dominant in his “complete” game on June 7 versus Knoxville. During the first game of a doubleheader, Burns was extremely efficient with 75% of his 80 pitches becoming strikes. In addition to his great pitching, the defense behind him made great plays with 18 balls in play. Burns a lot of the damage himself, creating 14 whiffs and 17 called strikes in his six-strikeout performance. He had a perfect game through 5.2 innings using a combination of the curveball, changeup, and slider to control the bottom half of the zone. And for the first time, he used his 97+ mph four-seamer up in the zone. This is an exciting development for a pitcher with an over-the-top delivery that tends to put a hittable angle on his fastball.

Burns is succeeding, and a 2025 Major League promotion is much more realistic than previously thought. All-Star Break in July is a conservative marker for when Burns could be a candidate for a spot start or called up as a longer-term solution. The Reds are playing .500 ball with a fluctuating rotation. Burns is an athletic righty who has a huge buzz on his name right now after this amazing performance and subsequent promotion. Stashing him now is highly advised after having a relatively successful Triple-A debut where he generated seven strikeouts on 11 whiffs over 5.1 innings.

 

6. Quinn Mathews, LHP, St. Louis Cardinals

2025 AAA Stat line: 23.0 IP | 3.81 ERA | 24.8 K% | 18.8 BB%

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

 

It was a weather-shortened outing for Quinn Mathews (“Mathews with one T” is how I say his name in my head every time I type it) on June 12 against Gwinnett. He managed to complete three innings before surpassing his pitch limit of 60 pitches. He was inefficient with a 40% zone rate and 60% strike rate, producing four walks. This is only his fourth start since a month-long layoff after shoulder soreness derailed his 2025 start, so it was reasonable that two 20+ pitch innings would hamper any length into the game. Mathews started 2025 with a 50% strike rate after sustaining a 64% strike rate in 2024.

Mathews is matching most of his current pitch metrics from 2025 and 2024. The changeup was the star pitch on this night, with its 12 inches of arm-side break generating seven whiffs. He averaged 94.9 mph in his most recent starts 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.

This ranking will fluctuate as his performance varies and the stash list names evolve. The hope is that he returns to the level of prospect that we saw ending the 2024 season.

 

7. Cade Cavalli, RHP, Washington Nationals

2025 A,AA,AAA Stat line: 37.1 IP | 2.89 ERA | 26.8 K% | 8.5 BB% 

2024 MiLB Stat line: 8.1 IP | 2.16 ERA | 41.9 K% | 16.1 BB%

 

Roman Anthony was called up earlier this week to form the Big 3 with the Boston Red Sox. Right before that promotion, Anthony was caught staring dumbfounded at a 98 mph fastball painted on the outside corner by Cade Cavalli. His velocity was up in this start, sitting at 97 mph and touching 99 mph. Although he only got two whiffs on the pitch, he added in another five called strikes, including the one to Anthony. The four-seamer has a mediocre induced vertical break around 14 inches with minimal horizontal movement. On the season, the fastball had been a below-average pitch at 95 mph, but we could see some better outcomes ahead if he can continue sitting above 97 mph. Cavalli finished five innings of scoreless work, limiting hard contact and giving up zero free passes.

Cavalli will be on an innings limit as he moves through the summer. He last pitched for any meaningful amount of time in 2022 when he reached 101 innings. Given his arm injury, it would be difficult to imagine that he greatly exceeds the century mark. That realization somewhat dampens any excitement about his performance in 2025, but it doesn’t mean he couldn’t provide significant value for the Nationals in the Major Leagues. With each healthy appearance, we will monitor extension and release heights since any deviation could signal passivity or holding back. Right now, his 6.3 feet of extension and release height of 6.2 feet do not add much benefit to his velocity. The big drop curveball will continue to be his best pitch, which could make some games difficult if he loses the feel for its spin. His impact on the Major League squad may be minimal for 2025 due to an innings limit, but Cavalli is a proximity stash with moderate strikeout upside if the velocity returns and holds.

 

8. Chase Petty, RHP, Cincinnati Reds

2025 AAA Stat line: 41.1 IP | 3.05 ERA | 27.4 K% | 10.9 BB%

2025 MLB Stat line: 5.1 IP | 21.94 ERA | 19.4 K% | 22.2 BB%

 

Chase Petty has all the tools to be a frontline starter in the Major Leagues, yet he doesn’t have the results to back up the hype. He incorporates five pitches across four different velocity bands that bend to all parts of the strike zone. The four-seamer and sinker are in the 94-96 mph range with an average induced vertical break, but a ridiculous horizontal break of at least 13 inches on each pitch. Lack of control of that tailing movement is a likely cause for his poor walk rate. His slider has a rare gyro-spin of 1.6 inches of arm-side break and produced a 46% whiff rate in Minor League action. His loopier sweeper is the only pitch that bends to the glove side on the regular with a 9 inches of movement. The sweeper has a 27% whiff rate and a .409 xWOBA as his least-used pitch at 9%. With a variety of weapons, Petty should get better results, but it all comes down to his ability to harness them.

For 2025, Petty has a 46% zone rate on his entire arsenal. In his June 7 start against Norfolk, he had a 50% zone rate on all his pitches, 57% on the four-seam fastball, and 0% on two sinkers thrown. It appears the sinker is his most difficult pitch to control, and its use is being reduced on days when he does not have the feel for it. He had a 71% zone rate on the pitch a few games back, good enough to earn one called strike, two balls, two flyouts, one groundout, and two run-scoring singles. This quick, surface-level examination makes it feel like ditching the sinker in the short term could improve his outcomes. Against the Tide, he went six innings to battle for eight strikeouts on ten whiffs, with nine on the slider. On the other hand, Petty still gave up hard contact with nine hard-hit balls, including one solo home run. The talent is here. The opening in the Reds’ rotation is here. Now is the time for Petty to put it all together so that he can earn another chance.

 

9. Nolan McLean RHP, New York Mets

2025 AA/AAA Stat line: 59.0 IP | 1.98 ERA | 25.7 K% | 10.8 BB% 

2024 MiLB Stat line: 109.2 IP | 3.78 ERA | 25.1 K% | 9.1 BB%

 

The New York Mets‘ pitching development department is generating numerous interesting prospect arms this season. Take a look at Jonah Tong, Blade Tidwell, Jack Wenninger, Felipe De La Cruz, Zach Thornton, Jose Chirinos, among many others, and today’s featured stash, Nolan McLean. The 6’2″ righty has now completed six appearances at the Triple-A level after an early promotion from Double-A. He has equipped himself well over those 32.2 innings, producing a 24% strikeout rate and 10.5% walk rate to go with a 2.48 ERA, a 1.13 WHIP, and a 2-2 record. In his latest outing, he followed Frankie Montas Jr. in his rehab start on August 8. He completed a mostly smooth 5.1 innings, giving up two hits, including one home run, and two walks.

McLean is another pitcher with a vast arsenal, throwing six pitch types, with four of those pitches occurring at 20% or greater usage. He leads with a sweeper that is producing a 38% whiff rate and a .215 xWOBA against it. The sweeper’s 14-inch break is modest, but he is releasing it at a low height to tempt hitters at the bottom of the zone. He follows up the sweeper with the sinker or four-seamer that has an increased velocity up to 95 mph. The sinker is the better performer at a 28% whiff rate and a .255 xWOBA against. His low arm angle is helping play up the 13 inches of induced vertical break on his fastball, but it isn’t helping, as seen by the 9% whiff rate and .356 xWOBA against. The cutter is one pitch that could see better results as it mirrors the release point of the sinker, but moves to the opposite side.

Overall, McLean has all of the tools to succeed in the Major Leagues. He has a solid pitch arsenal and is mostly generating weak contact on the ground. One obstacle is that another interesting arm with Triple-A Syracuse, Blake Tidwell, is already on the 40-man roster. They both have similar high walk rates with their six-pitch arsenals. Tidwell faltered in his first chances with the Mets, so maybe it’s time to test out McLean.

 

10. Cam Schlittler RHP, New York Yankees

2025 AA/AAA Stat line: 63.1 IP | 2.27 ERA | 31.3 K% | 9.1 BB% 

2024 MiLB Stat line: 120.2 IP | 3.36 ERA | 31.0 K% | 8.6 BB%

 

The New York Yankees are in first place in the American League East, but have never been content with cruising into the playoffs. Their current five-man rotation of Carlos Rodón, Max Fried, Clarke Schmidt, Will Warren, and Ryan Yarborough is getting the job done, but is not without its warts. Yarborough is likely the odd man out with Marcus Stroman returning and Luis Gil recovering later in the summer. And they have 29-year-old Allan Winans on the 40-man roster doing well in Triple-A Scranton. We are doing a roll call of the team to demonstrate the slim, but realistic pathway the organization has to continue being aggressive with the 24-year-old Cam Schlittler.

The 6’6″ righty recently made his Triple-A debut after starting the season in Double-A. He blossomed across three levels in 2024, striking out 150 batters over 120.2 innings with a 3.36 ERA and 1.27 WHIP. The Yankees even kept him on the spring training roster until late March, where he flashed his tremendous upside. He concluded the spring session with a four-inning scoreless start against the Phillies, balancing two strikeouts against one walk and three hits. His inclusion so late in the spring signaled that the organization has a belief that he can be a key contributor much sooner than anticipated, possibly even in 2025.

In his Triple-A debut against the St. Paul Saints, Schlittler produced eight strikeouts on 14 whiffs across his 86 pitches. It was a successful debut for Schlittler, who only allowed the one earned run on a solo home run in his final inning. Despite the perceived control issues with the high walk rate, he has done an amazing job throwing strikes in 2025, averaging 67% strikes per game. He eclipsed the 70% strike rate in this game, yet still allowed three walks, something he has done only three times out of his 11 appearances in 2025. Schlittler releases the ball from a 3/4 arm angle that generates minimal extension, a la a tall and fall delivery. The four-pitch mix is in development. His fastball velocity is around 96 mph, sometimes touching 99 mph with 15 inches of induced vertical break. Schlittler blends in a slider, a sweeper, and a curveball. With his current arsenal, he could benefit by incorporating a pitch with arm-side break, such as the changeup he dabbled with in spring training.

 

On The Bubble

Here are the next several pitchers that were in consideration for inclusion on this week’s list:

Gage Jump ATH (Dynasty add), Luis Morales ATH, Jack Perkins ATH, Hurston Waldrep ATL, Nathan Wiles ATL (Proximity add), Braxton Bragg BAL (Dynasty add), Brandon Clarke BOS (Dynasty add), Payton Tolle BOS (Dynasty add), Jaxon Wiggins CHC (Dynasty add), Noah Schultz CHW, Parker Messick CLE, Miguel Ullola HOU, Patrick Copen LAD (Dynasty add), Jack Wenninger NYM (Dynasty add), Jonah Tong NYM, Griffin Herring NYY (Dynasty add), Henry Baez SDP, Carson Whisenhunt SFG, Tekoah Roby STL (Had a poor AAA debut), Khal Stephen TOR (Dynasty Add), Trey Yesavage TOR (Dynasty add) & Travis Sykora WSN (Dynasty add).
