Kevin Luo's top hitter fantasy baseball prospects to stash for Week 15 (2025). His MLB prospects to pick up and stash on your bench and N/A spots in redraft leagues.
We had a couple of big hitting promotions this past week with Colby Thomas, Harry Ford, and Colson Montgomery all getting the call to the majors.
There are still several good prospects on the precipice of the majors ready to make a fantasy impact.
Let's look at a few top prospects to stash for Week 15 of the fantasy baseball season.

Samuel Basallo, C/1B, Baltimore Orioles
Some exciting personal news: The Orioles have signed me to their major league roster to play catcher... Just kidding! But at this point, it seems like that's more likely than them calling up their top catching prospect, Samuel Basallo, unfortunately.
The Orioles had an unbelievable string of catcher injuries over the last couple of weeks. In this time, they've had three catchers go on the IL (Adley Rutschman, Maverick Handley, and Chadwick Tromp). Gary Sanchez is also getting imaging on his finger. However, that has not motivated them to bring Basallo to the majors, which is extremely aggravating to all baseball fans.
I've written plenty of glowing words already about Basallo, and he continues to perform. He has a 147 WRC+ with 16 HRs and a powerful plate approach.

No one other than Mike Elias really knows when Basallo will get the call to the majors. However, when he does, he should be viewed as a top-10 fantasy catcher right away, with the upside to get into the top five quickly.
Carson Williams, SS, Tampa Bay Rays
I got a few questions about my low ranking of Carson Williams when I released my mid-season prospect rankings. He's someone who, to me, has always been a much more interesting real-life prospect than a fantasy prospect due to his strong shortstop defense.
Williams is actually coming off a fantastic season at Double-A in 2024 at only 21. He had a 142 WRC+ with 20 HRs and 33 SBs. His K-rate was also a palatable 28.5 percent. His follow-up season at Triple-A has been very up and down so far, though.
Williams still has a very exciting 14 HRs and 14 SBs, but he only has a 95 WRC+, and his K-rate has ballooned to 35.6 percent. However, he has started to figure things out and is heating up over the last month.

Three-quarters of the Rays' infield (Junior Caminero, Brandon Lowe, and Yandy Diaz/Jonathan Aranda) have been excellent this season, and the Rays just got their big free agent signing, Ha-Seong Kim, back from injury to round out their infield, so there isn't an immediate spot for Williams.
However, if he continues to hit like he is, he could be getting the call if the Rays get an injury to a member of their infield. When he gets the call, he should provide solid speed and power upside with a questionable batting average. One added component for Williams is that his great defense at a premium position will likely give him more playing time leeway, even if he struggles early on with the bat.
Moises Ballesteros, C, Chicago Cubs
I selfishly want to see Moises Ballesteros get another chance back in the majors, because baseball is more fun when meatball-shaped men are playing it at the highest level, and that's what Ballesteros is.
At the plate and in terms of appearance, he is very Alejandro Kirk-esque to me. He has an excellent hit tool with solid power. Ballesteros only got a short stint in the majors when he first got called up and didn't perform too well with only a 41 WRC+ in 18 PAs, but he was clearly not overwhelmed, as he walked more than he struck out.
At Triple-A this season, he has a 128 WRC+ with eight HRs and a very impressive plate approach.
While it's unclear the exact role the Cubs see for Ballesteros in the future (he's not a great defensive catcher), he could get more seasoning at the major league level as a backup catcher and occasional DH/1B. Their current catcher situation has not been that strong since the clock struck midnight on Carson Kelly's Cinderella offensive run.
When he gets the call, he'll be more of a target for two-catcher leagues. However, he could be a starting-caliber catcher if he gets enough playing time, especially in points leagues.
Chase DeLauter, OF, Cleveland Guardians
The Guardians' offense continues to be feeble, and Chase DeLauter continues to get on base in every game at Triple-A.

The Guardians have now been swept in back-to-back series against the Cubs and Cardinals, and they were shut out in half of the games. It's only a matter of time before they make some drastic changes to spark their offense a bit.
DeLauter should be one of those changes due to his strong Triple-A performance and the fact that he's actually healthy for once (why waste it?!). He has a 143 WRC+ so far this season in Triple-A with an equal K-rate and BB-rate.
The Guardians do not have an outfielder other than Steven Kwan with an over 100 WRC+, so there is definitely room for DeLauter in their outfield. If they don't make some changes soon, they'll find themselves out of the playoff race completely. When DeLauter gets the call, he is a worthwhile add in medium-sized leagues of all formats, but his profile is likely best suited for points leagues.
Kristian Campbell, 2B/SS/OF, Boston Red Sox
Similar to how I felt about Matt Shaw earlier this season, Kristian Campbell is getting a much-needed reset in Triple-A after really struggling through his last months in the majors.
Unlike Shaw, prior to his demotion, Campbell had an extended period of excellent play in the majors, where he had a 151 WRC+ in March and April, which shows how much upside he has when he's performing.
The Red Sox are likely waiting for Campbell to get hot, along with working on his defense (mostly at first base) in Triple-A, before he gets called back up. He hasn't done much yet since getting demoted, as he is hitting sub .200. However, he has a 121 WRC+ and a 25.6 percent BB-rate so far.
Campbell puts us within one!

I imagine we'll see Campbell in the majors again shortly after the All-Star break. While this season hasn't gone exactly as the Red Sox had hoped, seeing progress at the major league level for their three-star prospects should be a top priority for the organization.
When he returns, he has five category upside and should be owned in most formats, especially since he'll have a ton of positional flexibility for our rosters.
