Chris's fantasy baseball prospects to stash list for Week 10 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 10. Who are the top prospects you need to know for redraft leagues? Last week, we nailed the Jac Caglianone promotion, and it looks to be a big win for fantasy managers who stashed him. Who is next? I have you covered with names like Ryan Ritter, Andrew Painter, and Roman Anthony. Plus, who is Anthony Seigler?
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
The Rockies' signing of Orlando Arcia tried to kill our Ritter hype. It has not fazed Ritter, as he keeps hitting. While the home run barrage has slowed down, Ritter still has an 18-game hit streak, which will pair with a 24-game on-base streak. His slash line is strong: .305/.413/.635. Hey Rockies, do the right thing and put Ritter on the big league team.
Having an interesting skill set, Ritter has made tangible improvements this year, starting with his approach. After an alarming 34 percent chase rate last season, Ritter has dropped that number down to 25 percent, which is a notable improvement. He also shows 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 86 mph does not jump off the page and is honestly not great, he does have a 104 mph 90th percentile, which is solid to pair with a 37 percent hard-hit rate. The launch angles have helped lead to a nine percent barrel rate.
Ritter's contact numbers have steadily improved throughout the season, and he is striking out at just a 20 percent clip. The 70 percent contact rate could be better, but Ritter playing his home games in Coors Field will help mask some of the swing and miss, as he should run higher BABIPs to help out his batting average.
Last week was truly the time to bring Ritter up. I still think it is a matter of days at this point.
Andrew Painter, RHP - Philadelphia Phillies
Painter's start last night was bad. There is no nice way to put it. He walked four batters and served up two home runs in the hitter-friendly Truist Field in Charlotte. While the start might look discouraging for some and their hopes of seeing Painter soon, the adversity was good to see. While Painter did not have his best stuff and started the game with a leadoff home run, he battled back.
He ended his day of work by striking out Colson Montgomery and Andrew Vaughn. Painter has also continued to build up innings and has faced 21 batters in three of his last four starts. He is getting closer to being ready for the Majors.
Painter's fastball has sat at 97 mph and touched 100 mph. The velocity is fully back, and Painter's fastball averages around 18 inches of IVB from a 6'6" release height. The command will only get better with the pitch, but it already looks like the plus offering it was pre-surgery.
Painter's cutter has been his most-used secondary pitch. It is around 90 mph with good spin and carry, and misses bats at an impressive clip for a cutter. The slider is around 86 mph with more depth and nine inches of sweep and plays well off the cutter.
The curveball has remained strong, sitting between 80-82 mph. It has shown depth and sweeping action, averaging negative three inches of IVB and 10 inches of sweeping action. Painter has thrown his changeup sparingly this year as a distant fifth pitch. It sits around 90 mph with carry and 12 inches of fading action.
Anthony Seigler, C/2B - Milwaukee Brewers
Seigler has been in the minors since 2018, but has some pedigree as a former first-round pick. Selected by the Yankees out of Cartersville High School, Seigler received a $2.8 million bonus. He joined the Brewers organization this offseason and looks like a different player.
Seigler is hitting, and that has continued all season. You would need to go back to April 17 to find the last time that Seigler did not get on base. He has hits in 21 of his last 22 games and over that span has a .392/.500/.658 slash with three home runs and 12 extra base hits. For the season, Seigler is slashing .296/.440/.513 with six home runs and 16 stolen bases.
As you might expect from the high OBP, Seigler rarely chases pitches out of the zone, having an O-swing rate of 18 percent. The contact is good, as Siegler connects on 78 percent of swings overall and 85 percent in the zone.
While he may not be a huge source of power, Seigler consistently hits the ball hard, with a 50 percent hard-hit rate and a 91.7 mph average exit velocity. His versatility is highly attractive for the Brewers, as Seigler can catch or play in the infield. It would not be a surprise to see Seigler in a Brewers uniform soon.
Roman Anthony, OF - Boston Red Sox
Yes, this article is about stashing prospects for redraft leagues. Anthony is probably the biggest stash there is at this point. He is the top prospect in baseball, and the Super 2 deadline has passed. What are the Red Sox waiting for? I am here to be the bearer of bad news. Talks internally make it seem like it could be a while before we see Anthony.
Why? Well, there is a strong possibility Anthony could come up and win Rookie of the Year or finish second in the voting. The AL Rookie of the Year race is wide open right now. If Anthony finishes in the top two, he is awarded a full year of service time. Given that the Red Sox did not bring him up within the first two weeks of the season, the Red Sox are not eligible for a Prospect Promotion Incentive pick. Kristian Campbell also lines up to potentially give the Red Sox a pick. Do they hold Anthony down until August so he is prospect eligible in 2026? It sounds crazy, but who is to say that does not happen?
The Red Sox are nine games out of the AL East lead, which has surprisingly been a bad division. While the Red Sox are just four games out of the AL Wild Card race, the team is floundering. Is the team willing to give up a future year of control on Anthony, who is sure to bet on himself and not sign an extension, for a month of his bat in Boston in June? I don't have the exact answer, but I think it could be a little while before we see Anthony.
It is none of his own doing, though, as Anthony is slashing .296/.422/.493 with nine home runs and three stolen bases in Triple-A. Every night, it seems like a new Roman Anthony highlight where he blasts a ball 115 mph. When he comes up, though, Anthony is going to hit.
