The Stash List Week 9: Top 10 Pitching Prospects to Stash in 2025

top 10 pitching prospects to stash in redraft league

John Villavicencio
Dynasty 5/24/2025

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:

Noah Cameron impressed again in his second stint. The mediocre velocity revolution is here, as pitchers such as Cameron are experiencing success with 92 mph. The home run allowed was on an 87 mph four-seamer (maybe mislabeled pitch), but he is usually able to disguise it better with the movement and velocity on his secondaries.

Mick Abel hitting 99 mph, getting 18 whiffs, and nine strikeouts in his debut is pretty cool. A 4-pitch mix could work if he gets another start. Congrats, Abel!

After dispatching the White Sox, Cade Horton has great matchups versus the Marlins and Nationals. The whiffs were minimal in the May 16 start, and the home runs were up, so hopefully he can keep giving us at least five innings down the line.

Control was not in attendance for Zebby Matthews’ 2025 Major League debut. He threw 59% strikes, allowed three walks in a row at one point, and did not make it to the fourth inning. On the other hand, he allowed only one hard-hit ball and only singles. Let’s hope for better in his next start.

Mike Burrows started on Thursday, May 22, in what was likely a small toss-up for Bubba Chandler. Burrows went five innings with five earned runs allowed on four hits, two home runs, and two walks. One of the bombs was to contact hitter Joey Ortiz off a 95 mph fastball middle-middle. Burrows recovered to allow only one more baserunner using his changeup 31% of the time, with its 16 inches of break generating eight whiffs.

Carlos Rodríguez was recalled as long relief support and was hit hard in his 3.1 innings of work. He gave up 5 hard-hit balls. including two home runs. Rodriguez offers a balanced four-pitch mix with the changeup getting four whiffs on the night and 16 inches of break.

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. It’s “secondaries” week as we break down the second-most-used pitch in each pitcher’s repertoire, along with game film for you to review.

 

Top 10 Pitching Prospects to Stash

 

1. Bubba Chandler, RHP, Pittsburgh Pirates

2025 AAA Stat line: 37.1 IP | 2.17 ERA | 36.8 K% | 10.5 BB%

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

 

Time to take out the tissues as we celebrate Bubba Chandler’s promotion to the Major Leagues. Although a little teary-eyed to see him leave the stash list, we are grateful that we get to…wait…he is still in Triple-A? Are the Pirates watching his games? Oh, they approve and are holding him down? Got it. Who is blocking Chandler in the Pittsburgh organization? The likely obstacle is Mike Burrows. Carmen Mlodzinski, demoted this week, was admirably filling in as a starter with 39.2 innings pitched, but was on pace to exceed his 2024 innings total (69) in the next few weeks. Burrows is already on the 40-man roster and is coming off a three-start stretch with 23 strikeouts over 14.2 innings pitched. Chandler should take the mound on May 24 on the road at Toledo.

For his part, Chandler is building up to a Major League starter pitch count of 86 while increasing the strikeout rate to 36.8%. His control has wavered over the last four starts, but he is still producing double-digit whiffs in each of those games. He finished this game with 15 total whiffs and seven strikeouts. There are flashes of dominance with a changeup, slider, and curveball combination that helps keep batters off balance. He drills the lower glove-side corner of the strike zone with great effect. Then, he adds in a four-seamer that can touch 100 mph, and it’s no surprise why hitters are swinging and missing so much. The most immediate area to improve is consistently throwing strikes. Despite lacking the same pedigree, Mlodzinski owns a 6.7% walk rate, and Burrows is at 8.5%.

Chandler used the offseason to improve the velocity on all his pitches. For his changeup, it is up four mph with greater spin. In the May 18 outing, he only threw the changeup in the zone 48% of the time, and hitters still swung at 45% of changeups that were located outside of the zone. The additional inch-plus of movement got six whiffs on the evening. Yet, it isn’t as locked in as it was in 2024, with the whiff rate down to a robust 31%. Nevertheless, hitters are not putting the pitch into play with much authority (0.097 xWOBA) or frequency (0.065 AVG).

 

2. Mick Abel, RHP, Philadelphia Phillies

2025 AAA Stat line: 46.1 IP | 2.53 ERA | 26.6 K% | 9.9 BB% 

2025 MLB Stat line: 6.0 IP | 0.00 ERA | 40.9 K% | 0.0 BB%

 

It must have been satisfying for Mick Abel to continue his Triple-A momentum with a stellar Major League debut against the Pirates on May 18. Yet, there was a moment in the first inning when he had to overcome any butterflies with two baserunners on. He got a groundout and then proceeded to strike out the side in the second inning. Abel finished the game with an outstanding 18 whiffs, nine strikeouts, and an even more impressive clean slate for walks and runs. Although it was known that this was a spot start, Abel proved that his 2025 success is not a fluke and that he is deserving of another chance. Although Tajuan Walker will get the next start, there is no reason to believe that Walker needs to stay in the rotation. He returns to the stash list ahead of Andrew Painter for the fact that he is healthy, built out to 95+ pitches, and has demonstrated that he is ready to handle Major League hitters.

 

In his Phillies start, Abel used the curveball as his second-most-used pitch behind the 97 mph fastball. The breaking pitch features 6 inches of movement, 7.5 inches of drop, spinning in at 2632 rpm, and produced eight whiffs on 11 swings. Compared to his Minor League marks, the spin is up over 100 rpm, yet the movement is not as substantial. The jump in extension is exciting, and we hope it holds up over the season. The 73% whiff rate is over a small sample, but the curveball is getting a high of 34% whiffs in Triple-A. The major development concerning Abel’s pitch arsenal was his ability to throw 73% strikes and land 69% of his pitches in the zone. Historically, he has had mid-teens walk rates, but this performance shows that he can command pitches and do so for long stints.

 

3.  Joe Boyle, RHP, Tampa Bay Rays

2025 AAA Stat line: 41.0 IP | 1.98 ERA | 27.3 K% | 10.6 BB%

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

 

Joe Boyle excitement has reached a plateau after another clunker of a performance on May 20. He lost feel for his pitches, especially the slider, spiking it into the ground on numerous occasions. Boyle obliged the opposing lineup’s patience and observation of his wildness by allowing four walks. An additional byproduct of the lack of control is allowing the run game to flourish. Boyle allowed two steals in the game as he was likely spending a lot of mental energy focusing on hitting the catcher’s mitt. He finished the game after throwing 58% of his 77 pitches for strikes over four innings. He only got five strikeouts while allowing three runs to cross the plate, with two of them earned runs. This is not the ascending performance of someone who should earn an immediate call-up, but there are still reasons to stash him on your bench. We get to scout him on May 24 when he is scheduled to start at home for Lehigh Valley.

Despite the current stagnation, Boyle’s stuff is still attractive for dynasty managers. The batting averages against his pitches are amazingly low, with no rate above .182 in his Triple-A starts. The slider is his second-most-used pitch, earning a 43% whiff rate on the season with its tight spin of 2,569 rpm over 3 inches. The 6’8″ righty is not physically exerting himself to the fullest on each pitch with a measly extension of around 6.3 feet. The release height is at six feet, which offers a flatter attack angle to hitters, something that makes it more likely that hitters swing through the ball or connect with the pitch for a ground ball. In this game, Boyle earned 13 whiffs, with eight whiffs alone on the slider. It’s a strategic decision not to throw pitches in the zone, but the 35% zone rate for his slider is a mark made much lower by the high number of those sliders ending in non-competitive locations. Boyle is still generating double-digit whiffs each start, but we would like to see him pitch a clean effort more consistently throughout the game.

 

4. Jacob Misiorowski, RHP, Milwaukee Brewers

2025 AAA Stat line: 52.1 IP | 1.55 ERA | 31.3 K% | 10.0 BB%

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

 

Summer is quickly approaching as students from all levels of education finish their studies. Even with the bright sunny days on the way, storms are still rolling through parts of the country, disrupting baseball games. Jacob Misiorowski had his Tuesday start pushed back to the second game of a doubleheader on Wednesday, which likely shook up his throwing schedule. The J-Misfits, Misiorowski’s fictional fan club I made up, only got to watch him throw three innings in the nightcap. The J-Misfits also have to cope with disappointment after learning that Carlos Rodríguez would be the prospect call-up for the Brew Crew over the weekend. Misiorowski will remain with Nashville for at least another week after walking one and striking out four batters on a 66% strike rate.

A reliable secondary pitch will be something Misiorowski must identify before getting the call-up. His fastball is averaging 65% use, sometimes higher in a given game. While the four-seamer has a 33% whiff rate, the attack angle is hittable, and he needs to get hitters looking for something else. Right now, at 16% usage, the slider is moving with greater vertical movement at a slightly higher velocity. He is throwing his entire arsenal with greater extension and from a lower release height, signalling that he is putting more effort into finishing his delivery this year. He is experiencing a modest increase in production from the pitch with a higher whiff rate and .147 batting average against the pitch.

 

5. Andrew Painter, RHP, Philadelphia Phillies

2025 A+, AAA Stat line: 23.1 IP | 3.09 ERA | 28.1 K% | 7.3 BB%

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

 

Andrew Painter threw a great game, but I have a suggestion for how he could be even better. Wear prescription glasses. No, seriously. He initiated four challenges, only two of them acknowledged by the home plate umpire. He was incorrect on all four challenges, and each was at least a few inches off. The cherry on top of his poor vision decisions occurred when he began walking off the mound on what he thought was a strike three. The Brushback Bros, Painter’s fictional fan club I made up, all groaned when he made the pitching faux pas. The final line was 13 whiffs on 71 pitches with seven strikeouts and one walk. He allowed two runs (one earned) on three hits and only three hard-hit balls.

Mick Abel’s stellar spot start has earned him the badge for proximity, but Painter is on track for a July call-up. This is probably the best time to stash or trade. Any initial excitement from seeing him pitch in Triple-A will have cooled, as his fantasy managers may get anxious waiting another month or so for his debut.

There are dabs of sliders, curves, and changeups along with large plops of the cutter and four-seamer on Painter’s palette. Over the last month, he has doubled his use of the curveball. Yet, he only threw it three times on Wednesday. The slider was also sparingly used this week, only six times. This is likely due to the wet conditions, but something to monitor in his next start. Either way, these pitches are achieving fantastic whiff rates while limiting the damage on any contact made.

 

6. Carson Whisenhunt, LHP, San Francisco Giants

2025 AAA Stat line: 51.0 IP | 3.00 ERA | 25.9 K% | 3.5 BB% 

2024 MiLB Stat line: 109.2 IP | 5.17 ERA | 28.4 K% | 11.3 BB%

 

The balanced attack continues for the tatted-up Carson Whisenhunt. After throwing 50% sinkers at the start of the season, Whisenhunt is mixing in more of his best pitch, the changeup, and the slider with better results to show for it. The changeup is at a 40% whiff rate with 16 inches of arm side break. The slider bends to the glove side six inches with 2660 rpm and is getting whiffs 30% of the time. Hitters have no higher than a .167 batting average against both pitches, with only six extra-base hits over 123 at-bats on the season. On the other hand, his sinker carries an 18% whiff rate coming into the plate at 93 mph with 15 inches of induced vertical break. In his latest outing, the sinker was better than usual, earning four whiffs and up to 95 mph. He finished the game with his fourth consecutive seven-inning performance.

 

Although Whisenhunt is being deemed the ace of the Rivercats staff by the team announcers, seven other Sacramento pitchers are already on the 40-man roster. Nevertheless, the Giants have already moved around one of their starters, Jordan Hicks, with Justin Verlander beginning to succumb to injuries that could spell the end of his run with the team. Whisenhunt has the main advantage as the only left-handed pitcher within a plausible range of joining San Francisco. Let’s see how he does in a road start in Oklahoma City on May 24.

 

7. Ian Seymour, LHP, Tampa Bay Rays

2025 AAA Stat line: 45.0 IP | 2.40 ERA | 31.4 K% | 6.3 BB% 

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

 

His time will come, but Ian Seymour needs to avoid middling starts where he loses control if he wants to get promoted in 2025. On May 16, he threw less than 60% of his 92 pitches, while walking two batters and hitting one. He also gave up seven hard-hit balls and 11 fly balls, something he would want to avoid in the humid conditions of George M. Steinbrenner Field if and when he makes the Major League squad. While he allowed the most runs on the season in this game, Seymour also produced 15 whiffs with eight on the changeup alone. His delivery and velocity are deceptive enough that hitters are not always able to time his five-pitch mix. Ultimately, he was done in by a 27-pitch first inning and a 35-pitch third inning when he lost the feel for his pitches.

Seymour will surpass 100 innings pitched in Triple-A with his scheduled start against Worcester on May 22. In that time, he has pitched to no higher than a 2.40 ERA and 1.20 WHIP, with 123 strikeouts and 31 walks. This season, he has increased his velocity and improved some of the movement on his pitches. Subsequently, he has improved his  WHIP and ERA has held steady, but gained a few percentage points on K% – BB% to 25.1%. His changeup is the star performer, and he has treated it as such by increasing his year-to-year usage. The spin is up 90 rpm with the same velocity, but almost 3 more inches of arm-side break. He releases the curveball in a similar area, which likely helps play up the changeup’s productivity since they move in opposite directions. The 2025 version of Seymour is capable of producing solid results despite the mediocre velocity, especially if he can continue to limit fly balls.

 

8. Jonah Tong, RHP, New York Mets

2025 AA Stat line: 34.0 IP | 2.12 ERA | 43.4 K% | 11.8 BB% 

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

 

The New York Mets are one of a handful of organizations developing fantastic prospect pitchers at the moment. They have Jack Wenninger, Nolan McLean, Blade Tidwell, Felipe de la Cruz, and today’s number nine stash, Jonah Tong. Tong is a 2022 seventh-round draft pick who advanced through three levels in 2024 to begin this year in Double-A Binghamton. His delivery is reminiscent of Tim Lincecum with the over-the-top motion and deep follow-through to nearly touching the ground. He is utilizing a mix of fastball, curveball, changeup, and slider, all coming from a very high release point. His immediate area to improve is the control with a high walk rate inching above 11% for the season. Nevertheless, Tong has put himself in promotion territory as the Double-A strikeout leader with 59 punch-outs over 34.0 innings to start this season.

There are obvious reasons to be excited about the increased strikeout rate, yet there are a few things to be cautious of, especially if Tong does get a bump to Triple-A. Hitters are placing the ball on the ground a high 62% of the time against him, a dramatic increase from previous seasons that will likely regress closer to his 50% career mark. The 60% pull rate signals that Double-A hitters are early on his pitches, something that may change across levels. Hitters are swinging and missing at 17% of his pitches, despite locating a feeble 60% of his pitches for strikes. More patient lineups will turn his non-competitive pitches into more walks.

 

Tong continued his streak of games with double-digit whiffs after his six-inning victory against the Hartford Yard Goats on May 17. He finished the game with eight strikeouts, two hits, and two walks, while allowing zero runners to cross home plate. Without Statcast data, I cannot confirm, but it appears that Tong is throwing a 97-98 mph four-seamer as well as a 94-95 cutter. His main bugaboo is throwing the slider consistently in a desirable plane for hitters to swing at. Since he is coming from such a high arm angle, it seems to either break far off the plate or down into the ground. The changeup seems like the emerging putaway pitch at 85 mph, running a nice break to the arm side. As his pitch counts soar into the 90-100 range, there will be great interest from Mets fans and fantasy managers alike to see what strikeout numbers Tong could post at the next level.

 

9. Chase Burns RHP, Cincinnati Reds

2025 AAA Stat line: 35.2 IP | 2.27 ERA | 41.4 K% | 6.0 BB% 

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

 

Although he is still being brought along slowly, Chase Burns is a prime candidate for a 2025 Major League call-up. Burns is twenty-two years old and was selected as the number two overall pick in the 2024 draft. He is building up slowly to a big league pitch count, reaching a high of 74 on the season. He is further blocked by a stable of average arms in the Cincinnati Reds organization, so his inclusion is an acknowledgement of his tremendous upside. In 2024, he reached 100 innings with Wake Forest, which will likely limit any six-inning outing in the near term. Nevertheless, we are looking for clean games, high whiffs, and a healthy outlook for a potential summer call-up.

Burns utilizes a four-pitch mix that includes an upper-90s fastball. His slider has been slapped with a 70-grade due to its superior movement and velocity. He is known for throwing both a gyro slider low in the zone as well as the sweeping variety. Either way, the pitch gets the whiffs. In his most recent game, he tallied ten swings and misses along with seven strikeouts in misty conditions against Rocket City.

 

10. Noah Schultz, LHP, Chicago White Sox

2025 AA Stat line: 32.2 IP | 3.58 ERA | 23.6 K% | 13.9 BB%

2024 MiLB Stat line: 88.1 IP | 2.24 ERA | 32.1 K% | 6.7 BB%

 

It’s time for the real Noah Schultz to step up or step back. He continues to be his own worst enemy, starting and stopping momentum for a call-up from week to week. This is a down week as he allowed five earned runs from only seven balls in play and four walks in a start against Chattanooga on May 18. It was hard to produce a lockdown performance in this game with a 57% strike rate, but he did manage 13 whiffs and six strikeouts. It wasn’t enough as he hit a batter with the bases loaded to signal the end of his appearance in the fourth inning. He will look for redemption during a scheduled start in Pensacola on May 24.

While the walk rate is high, it is not due to poor control, but rather not making his pitches competitive enough to elicit swings from hitters. Schultz continues to deliver the vast majority of his breaking and offspeed pitches to the lower glove-side corner of the strike zone. To his defense, each day’s umpire calls a different game, and Schultz was burned by a few non-strike calls in this game. Nevertheless, the sweeping slider is inconsistent with its productivity from game to game. Furthermore, he has horrible splits with a 1.024 OPS versus lefties and a .324 OPS against righties on all pitches. Hitters are stroking almost 50% of his pitches into the opposite field. In addition, his ratio of groundballs to fly balls is falling from last year, which is not helped by the .388 BABIP against him. He will need to develop a better pitch that breaks to the arm side or overhaul his pitch mix to combat this distinction.

 

On The Bubble

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

Cristian Mena ARI, Gage Jump ATH (Dynasty add), Hurston Waldrep ATL, Braxton Bragg BAL (Dynasty add), Brandon Clarke BOS (Dynasty add), Payton Tolle BOS (Dynasty add), Jaxon Wiggins CHC (Dynasty add), Parker Messick CLE, AJ Blubaugh HOU, Luinder Avila KCR, Patrick Copen LAD (Dynasty add), Sean Linan LAD (Promoted to AAA at 20 years old), Jack Wenninger NYM (Dynasty add), Nolan McLean NYM, Cam Schlittler NYY (Dynasty add), Griffin Herring NYY (Dynasty add), Janson Junk MIA (wild card, but having AAA success), Henry Baez SDP, Michael McGreevy STL, & Trey Yesavage (Dynasty add).

 

Off The List

Here are a few pitchers that have fallen off the stash list:

Caden Dana LAA (too many fly balls as predicted),  Hunter Barco (arm injury), Quinn Mathews STL (Hasn’t started rehab yet), J.T. Ginn ATH (another IL stint), Rhett Lowder CIN (Left game with trainer, oblique injury possible), Brandon Sproat NYM (Poor performances), Robby Snelling MIA (Buried in Double-A & doing ok), George Klassen LAA (Concussion IL), & Chase Petty CIN (Needs a series of rebound starts before being considered again).
