Chris's fantasy baseball prospects to stash list for Week 20 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 20. Who are the top prospects you need to know for redraft leagues? We are back on our hot streak of predicting prospects getting the call, with at least one player in 10 of the last 11 articles getting called up within the week of the article being published. Let's break down some new prospects to stash, such as Kristian Campbell, Dylan Beavers, Robby Snelling, and Bryce Eldridge.
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 in terms of 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 significant impact in redraft leagues for the remainder of the 2025 season and are expected to debut in the major leagues soon.

Robby Snelling, LHP - Miami Marlins
The move to Triple-A has seemingly made Snelling better, and his last two starts have been nothing but dominance. Coming off a career-best start to the end of July, where he struck out 11 batters across 6.2 innings, Snelling's next start consisted of six innings of one-run ball with seven strikeouts. Snelling has not allowed a walk in his last two starts.
When you look at Snelling, his strong frame probably does not scream premium athlete. But he is an exceptional athlete who was a four-star linebacker recruit, heading to LSU for both baseball and football. He spent little time focusing on baseball alone until being drafted. While 2023 was incredible, 2024 was a step in the wrong direction as Snelling posted a 6.01 ERA and a 5.50 FIP in 73 innings with the Padres’ Double-A affiliate before being traded to Miami for Tanner Scott. He did make improvements over the final two months of the season with Miami.
What Snelling has shown in 2025 looks back to the level of arm talent we saw in 2023, when he was named Baseball America’s Minor League Pitcher of the Year. His ERA is down to 3.26 on the year and is backed by a 2.84 xFIP and 3.09 FIP. The command has steadily improved, and Snelling is rocking a 21 percent strikeout minus walk rate.
The fastball used to sit in the low 90s with 16 inches of IVB from a 5’8” release height. Now, it is up to 95 mph on average with over 17 inches of IVB on average. Snelling gets 7-10 inches of arm-side movement with high spin rates for a four-seam and has shown the ability to miss bats.
His slider has some “slurvey” traits, having good depth and sweeping action. It's not quite a curveball, sitting in the low 80s, but it has a -5-inch IVB with 8-10 inches of horizontal. He is comfortable throwing it both in and out of the zone, getting whiffs and chasing. It runs away from left-handed hitters, but Snelling will also throw it to right-handers back foot on occasion.
The changeup has played quite well, generating 14 inches of fade on average while working around 88 mph. The added fastball velocity allows the changeup to play better now, given the separation between the pitches.
With a strike rate of 66.5 percent and a walk rate below 7 percent, Snelling looks the part of a high-end pitching prospect again. He should get a shot to pitch with the Marlins over the next few weeks.

Dylan Beavers, OF - Baltimore Orioles
Every day that passes brings us another day closer to a Dylan Beavers debut. The performance gets better with each game that passes, and the only thing holding him in Triple-A is the Orioles' desire for Beavers to retain prospect eligibility for 2026. A call-up should come over the next two weeks.
A few small tweaks in the swing have unlocked a ton. It starts with a much smaller leg kick. Beavers is getting his foot down much earlier and is timing things up well. His hands are also in a slightly high position at the start of his swing. Last year, Beavers tipped the barrel a bit and had his hands slightly below his shoulders before the start of his swing. This year, his hands are a little above his shoulders before dropping the swing into the slot.
Beavers is up to 18 home runs in 379 plate appearances, blowing past his career-best 15 that he hit in 531 plate appearances last season. The contact numbers have improved, and Beavers has seen his strikeout rate fall from 23.5 percent to 17 percent in 2025.
The Statcast data has steadily improved for Beavers throughout the course of the 2025 season. His average exit velocity of 88.5 mph has steadily risen all season, but the 105.4 90th-percentile exit velocity is close to plus. Being a selective hitter, Beavers picks his spots well and has great launch angles.
While Beavers is not the fastest runner, he has good reads and jumps on the basepaths. Expect Beavers to be a consistent 20 home run/20 stolen base type threat who will put up respectable batting averages and OBPs. He honestly might be what some hoped Colton Cowser would be.
Kristian Campbell, INF/OF - Boston Red Sox
Campbell has finally been getting things going at the plate. After an improbable rise through the minors last year, Campbell made the Opening Day roster for the Red Sox and looked pretty good to start the season. Pitchers adjusted to him and over his most recent 104 plate appearances with Boston, Campbell slashed a smooth .176/.279/.231 with just one home run and a 29 percent strikeout rate.
The demotion to Triple-A didn't do much good, either. Campbell struck out in 34 percent of plate appearances while slashing .186/.352/.300 in 20 games. Coming out of the All-Star break, Campbell looks like a completely different hitter. He is rocking a 14-game hitting streak and has three homers and five extra-base hits over that span. The strikeouts have fallen, and Campbell is showing a much-improved approach at the plate.
Campbell seems to have re-found his groove while also working through a rib injury and some swing adjustments. This is a pretty typical process for most prospects. For hitters, especially, a prospect comes up and looks the part, but eventually, pitchers adjust. For Campbell, the first time he struggled and faced adversity was probably a good thing for him. He should return mentally tougher and mechanically more prepared to face MLB pitching.
So, what are the long-term expectations for Campbell? I still see a multi-position player who will hit 20 home runs consistently and steal 15-20 bases. I know you can call out the lack of stolen bases this year, but that is largely injury-related. If we are honest, Campbell was probably rushed. Not every prospect thrives in the majors right away. Expect Campbell to get back in Boston soon and be part of its postseason run.
Bryce Eldridge, 1B - San Francisco Giants
Few prospects had the meteoric rise that Eldridge made in 2024. The talent level has long been known since he was selected 16th overall in the 2023 MLB Draft. Selected as a two-way prospect, Eldridge gave up pitching immediately and then shifted from outfield solely to first base in 2024. Despite spending time injured this year, Eldridge has mashed when on the field.
There is no denying the kind of power Eldridge brings to the table, as his 90th percentile exit velocity of 109 mph is a high-end mark for a 20-year-old. Not only does he hit the ball hard, but Eldridge also puts batted balls at ideal angles and has a barrel rate of 16 percent.
Eldridge is aggressive on pitches in the zone, especially over the heart of the plate. The approach and contact skills are around average, but when you have 70-grade power, the profile can work. His average exit velocity, being north of 95 mph, stands out in a big way, as does a 116 mph max exit velocity.
The swing is relatively smooth, and the power comes naturally. Eldridge uses a toe-tap on all counts and starts with his hands high pre-swing before dropping them down into a slot to begin his swing. The bat's speed is electric, and Eldridge has strong wrists to help generate power.
Considering how long his arms are, the swing is relatively short, and he has a direct path to the ball. The contact rates have been a tad lower this year and are below average overall, but you can live with an 81 percent zone-contact rate with how hard Eldridge hits the ball.
Expect Eldridge to get a shot in a Giants uniform at some point soon.
