Top Prospects To Stash

By: The Lab | 05/29/26

We always need to be on top of the NEXT guy to be called up. Let's look into who's rising up the Stash List.

Kade Anderson

It should come as no surprise to anyone who follows me on X that Kade Anderson is my #1 LFX Stash. For me, it’s not about proximity. It’s about the type of impact he can make when he arrives. For the majority of prospects, they come up with buzz surrounding them, they show some promise at first, then fizzle out a few weeks later, as impatient owners drop them for the next hot pickup.

In the case of Kade Anderson, I believe he’s got as good of a shot as any prospect to replicate the type of rookie season numbers of the 2025 versions of Chase Burns, Jacob Misiorowski, Cam Schlittler, and Nolan McLean. While he doesn’t have the same strikeout upside as a couple of those guys, he should absolutely be able to put up elite ratios right away. He’s polished, he’s ready, and it’s just a matter of time until the Mariners rotation hits some bumps and/or injuries that open a rotation spot. You will want Kade when that happens.

Season Line: 1.63 ERA, 0.80 WHIP, 580 K in 38.2 IP

River Ryan

If proximity is your thing, then stashing Ryan is something you’re going to want to do as soon as you can. He had yet another dominant outing yesterday and was stretched out to 87 pitches. The Dodgers haven’t tipped their hand when they will call him up, but speculation is building that it could be as soon as his next start.

His potential reminds me a lot of 2025 Emmet Sheehan, where you knew his great stuff was going to play, as soon as he locked in a rotation spot. Rewinding to 2024, River Ryan flashed immense potential as a future rock for the Dodgers. He unfortunately blew out his arm and has been on the TJ road to recovery ever since.

A couple of caveats about his value for this season. Dave Roberts called it a "slim possibility" River Ryan would replace Blake Snell in the rotation a couple weeks ago. I think this was in large part due to Ryan having just come off the IL himself and was nowhere near stretched out enough. The other caveat is that he will likely have strict pitch count and innings limit issues this year, so he might not be in the rotation the rest of the season. But while he's there, you're more likely than not to want him on your teams and probably even in your lineups.

Season Line: 2.05 ERA, 0.91 WHIP, 29 K in 22 IP

Luis Lara

The alarm bells are sounding for Lara right now, as he's been red hot and the Brewers corner Outfielders have been underwhelming, to say the least. With Lara, both the power and swing-and-miss have improved. He's putting a lot of balls in play and getting on base at an outstanding clip. He feels like he can be a regular contributor if these skillsets transfer over.

Season Slash: .346/.450/.518/.968 with 7 HR and 18 SB

Max Clark

Another future impact over current proximity guy, Clark may not arrive in the immediate future. But he's got a fun all around skillset and is a higher rated prospect than some of the other bats on this list. He's gone through some prolonged cold spells this year and the hope is that once he makes those adjustments, he will be better equipped to handle MLB pitching. Don't add him just because he's got good stats, add him because you want a guy with the best potential to stick on your roster.

Season Slash: .268/.344/.389/.733 with 2 HR and 12 SB

Edwin Arroyo

He could be up at any moment, as one of the closest proximity guys on this list. Stash now if you like to trial and rotate. My strategy in leagues where this is viable, is to add prospects right before or right after their debut. Trial them for a couple weeks or a couple starts for a pitcher, and then if you're not seeing signs of production, go ahead and cut them for the next hot pickup. Eventually, you land on one guy that sticks this way. In my experience, it's typically been a better use of my final bench spot than clinging to a vanilla veteran.

Season Slash: .332/.393/.567/.960 with 10 HR and 9 SB

Kaelen Culpepper

He should have already been up, to be honest, when Royce Lewis was optioned. Instead, the Twins have gone with a rotation of Tristan Gray and Orlando Arcia at Shortstop. With Brooks Lee moved over to 3B, Shortstop is wide open for Culpepper to take over and stick. I'd expect him to be ROS guy once called up. He may not be a world-beater in his rookie season, but he's got enough juice to be worth the squeeze.

Season Slash: .246/.349/.462/.811 with 11 HR and 12 SB

Joshua Baez

I needed to mention Baez because he's been so red hot in May, hitting a Home Run every other game. Clearly, that makes him worth our attention. He's getting scooped up in a lot of shallower leagues right now, so he's on everyone's radar. If he is someone you want, you might not want to wait this one out any longer. I will caution with him though, his contact rates have not been the best, and it's led to an increase in strikeouts. That seems like something MLB pitching will exploit, and force him to adjust to.

Season Slash: .257/.338/.578/.916 with 16 HR and 11 SB

Thomas White

We had a flash a couple weeks ago of thinking Thomas White was about to be promoted. The Marlins had optioned Braxton Garrett, creating a hole in their rotation. White was then scratched from his own appearance about an hour later. I started connecting the dots and recommended to add him. Some outlets strating connecting the same dots and placed him as a projected Marlins starting pitcher for the weekend.

All of that came screeching to a halt when they placed him on the minor league IL. He was clearly scratched due to injury and not due to impending promotion. The reasoning to add him remains the same, albeit with a delayed timeline. There is an opening in the rotation, and he is their top pitching prospect, with Robby Snelling succumbing to TJ. I'd expect a lot of strikeouts and a relatively higher whip when he does arrive. Still makes for an interesting stash if you have the time to wait for him.

Season Line: 4.01 ERA, 1.46 WHIP, 35 K in 24.2 IP

LFX TIP: LFX is a powerful baseline, but it doesn't replace fast-moving news like prospect callups or injuries. Use it as your foundation, then layer on the latest context.
