Chris's fantasy baseball prospects to stash list for Week 9 of 2025. HIs top MLB prospects and rookie sleepers to make fantasy impacts this year when called up.
Welcome, friends, to the 2025 MLB season, and my weekly article about fantasy baseball prospects to stash heading into Week 9. Who are the top prospects you need to know for redraft leagues? I have you covered with names like Ryan Ritter, Jacob Misiorowski, Jac Caglianone, and more!
Winning in a fantasy baseball redraft league requires a nice blend of high-floor players and upside shots. While prospects present more risk in a one-year setting, such as a redraft league, they pay big dividends if they succeed. The reward could be huge if these players receive adequate playing time and perform well.
Throughout the season, there will be plenty of prospects who will get promoted and make an impact on their respective MLB teams and fantasy teams. Getting ahead of the curve on these players can pay huge dividends regarding FAAB bids. You can save money and have your league mates question how you are already in on that player so far in advance. Here are this week's fantasy baseball prospects to stash. These players can make a splash in redraft leagues for the remainder of the 2025 season and are expected to debut in the big leagues soon.

Ryan Ritter, SS - Colorado Rockies
Ritter might be the hottest hitter in the minors at this point, and he could be on the verge of getting a call-up to Colorado. After blasting three home runs last Sunday, Ritter began his week with two more on Tuesday. Ritters is currently riding an 11-game hitting streak, and over that span, he is slashing .443/.485/1.000 with seven home runs and 18 extra base hits.
Having an interesting skillset, Ritter has made tangible improvements this year, starting with his approach. After a bad 34 percent chase rate last season, Ritter has dropped that number down to 24 percent, which is a notable improvement. He is also showing improved strike-zone awareness, swinging at way more balls in the zone and over the heart of the plate.
While Ritter’s average exit velocity of 87 mph does not jump off the page, he does have a 104 mph 90th percentile, which is solid to pair with a 40 percent hard-hit rate. The launch angles have helped lead to a nine percent barrel rate.
The contact rate of 69 percent is slightly concerning, and his in-zone contact rate of 76 percent does not help give us more confidence. There is a strong power and speed blend, and seeing Ritter in person in the Arizona Fall League, he was much more physical than I anticipated. He looked solid in the field, and when he connects, Ritter shows strong exit velocities. The problem is that the contact rates have been highly concerning.
Regardless, some of those things can be masked by playing in Coors Field. If Ritter keeps hitting like this, it could be a matter of days before we see him in a Rockies uniform.
Jacob Misiorowski, RHP - Milwaukee Brewers
What Misiorowski is doing right now is unheard of. He continues to shred hitters apart and limit damage. Dating back to April 22, which includes seven starts and 37.2 innings, Misiorowski has a 0.96 ERA and has struck out 35 percent of batters faced. The walk rate of seven percent is also quite impressive, given that we saw him walk 14.4 percent of batters last season.
Misiorowski broke fastball traits on the Hawkeye machine as he threw 103 mph. While that is rare to see, what is even crazier is the pitch metrics. He created a -3.05 VAA on the pitch and 13.2 inches of iVB from a 5’2” release height. It had 7’6” of extension on it as well, creating a perceived velocity of 105.4 mph. Good luck, hitters.
His best swing-and-miss secondary pitch is the mid-80s curveball. The curveball sits at 85 mph with good depth and five to six inches of sweep. Misiorowski's slider/cutter sits 92-93 mph and has touched 96. The pitch has some carry and an inch or two of horizontal movement. He even throws a 90 mph changeup.
The arsenal is absurd here. The Brewers are wasting Misiorowski and Triple-A hitters’ time right now. Get this guy to Milwaukee.
Jac Caglianone, 1B/OF - Kansas City Royals
Caglianone continues to rake, and it is getting harder and harder to keep him in the minors. After dominating in Double-A, Caglianone got the call to Triple-A Omaha and had five home runs in his first series. The home run total is up to 14, and he pairs that with nine doubles and a strong .326/.387/.599 slash between both levels.
Running a 90th percentile exit velocity of 111.6 mph across both levels is a mark that is only bested by Oneil Cruz, Aaron Judge, and Vladimir Guerrero Jr. this year. This is not a new thing, though, as we have known that Caglianone's power is elite for a long time.
The approach has been cleaned up a bit, and Caglianone is making more than enough contact. The overall contact rate is up to 74 percent, with an in-zone mark of around 84 percent. That, paired with an improved chase rate, is good. Right now, Caglianone is chasing around 34 percent of the pitches he has seen out of the zone. In his first week at Triple-A, the mark was around 39 percent, which makes me wonder what it would look like against Major League pitching.
Regardless, Caglianone can swing it. It is some of the best power in all of baseball. Now, he is also getting work in the outfield, which may slow play promotions a bit. Once comfortable out there, Caglianone is going to get the call to Kansas City.
Cade Cavalli, RHP - Washington Nationals
There has never been much doubt of Cavalli’s stuff dating back to his days at Oklahoma, but the durability is somewhat concerning. In his first pro season in 2021, Cavalli made it to Triple-A and had the most successful season of his career, pitching 123.1 innings with a 3.36 ERA and 175 strikeouts.
In a season where Cavalli was slated to return to action in 2024, he pitched just eight innings due to a “dead arm” and the flu, setting him back when he returned to High-A. After some bumpy starts to begin 2025, Cavalli is settling in and could find himself in the Nationals' rotation soon. His most recent Triple-A start was dominant, striking out ten batters across five scoreless innings with just three hits and a walk allowed. That gives him a 1.29 ERA across his last three starts with a 40 percent strikeout rate to just a five percent walk rate.
Cavalli has his velocity back with a fastball sitting 95 and touching 98 mph. He is showing a four-seam and a two-seam fastball to keep hitters on their toes while featuring a curve, slider, and changeup. The curve is his most-used secondary, which sits in the mid-80s and has a strong two-plane break. The slider is plating more like a cutter right now, sitting north of 91 mph, and the changeup is working 88-89 mph with 17 inches of arm-side fade on average.
While he may be 26 years old, it is encouraging to see Cavalli back healthy. The arm talent has always been there, it is just a matter of him being consistently on the mound, which we are getting now. It seems like a strong possibility we see Cavalli get a start in Washington in early June.
