Frank Ammirante's hitter fantasy baseball prospects to stash for Week 11 (2026). His MLB prospects to pick up and stash on your bench and N/A spots in redraft leagues.
It's now Week 11 of the 2026 MLB season. As always, we're diving into ways to make our fantasy baseball teams better. One of the best ways to do that is by staying on top of the waiver wire, considering which top-hitting prospects you should stash. These are players who can sometimes make an immediate impact. Just look at Nick Kurtz with the Athletics last year.
Last week, we highlighted Luis Lara, Ralphy Velazquez, Jett Williams, Charlie Condon, and Jimmy Crooks, with Crooks finally getting called up by the Cardinals. We aim to switch it up each week to keep things fresh, so we're going with five different hitters for this week.
With that in mind, let's take a closer look at why Joshua Baez, Kaelen Culpepper, Max Clark, Braden Montgomery, and Abimelec Ortiz are my five stashes to highlight this week.

Joshua Baez, OF, St. Louis Cardinals
Baez has been featured often in this column, which highlights how much I like him as a prospect. Remember, this is a hitter who put up 20 home runs and 54 stolen bases in 499 plate appearances across all minor league levels last season.
The biggest question mark is his ability to make contact, as he has a 30.8% strikeout rate so far this year. However, we saw Baez maintain a 20.6% strikeout rate in Double-A last season, so it's likely only a matter of time before he figures it out at Triple-A.

Baez has been absolutely mashing of late, bringing his season-long slash line to .271/.350/.595 with 17 home runs and 11 stolen bases in only 237 plate appearances. This is the kind of fantasy-friendly profile that you want to bet on. There's just so much power and speed upside here.
When you look at the Cardinals' roster, you see that both left field (Bryan Torres) and center field (Victor Scott II) are pretty wide open. Even when Lars Nootbaar and Nathan Church come back, you have to think that they'll want to see what they have in Baez.
That's what makes this dynamic outfielder the top hitting prospect stash right now.
Kaelen Culpepper, SS, Minnesota Twins
It feels like Culpepper's call-up would have come any day now, especially with him slashing .265/.368/.488 with 13 home runs and 13 stolen bases in 253 plate appearances at Triple-A. You have to love how Culpepper has maintained a 12.6% walk rate and a 19.0% strikeout rate in his age-23 season.
The Twins are a rebuilding team, but it looks like they want to be patient with Culpepper. Even though you have Luke Keaschall struggling at second base and Tristan Gray platooning at shortstop, they still haven't brought up Culpepper.

But if Culpepper can continue mashing, he's going to force the Twins' hand sooner rather than later. As a hitter who put up 20 homers and 25 steals in 517 plate appearances across all minor league levels last year, there's plenty of upside here.
My other concern is that Royce Lewis has been absolutely mashing since getting demoted to Triple-A, so the Twins may opt to bring him up before Culpepper. With that in mind, you may want to be patient here, but when the day comes when Culpepper is up, it's likely to be worth the wait.
Max Clark, OF, Detroit Tigers
Clark is starting to figure things out at Triple-A, now slashing .263/.350/.402 with four home runs and 12 stolen bases in 240 plate appearances. At 21 years old, Clark is showing strong plate discipline skills, including an 11.3% walk rate and a 15.0% strikeout rate.
Those are the kind of metrics that give Clark a high floor once the Tigers finally make the move to call him up.

The Tigers are falling well short of a playoff spot in what's starting to look like a lost season. That means that they're incentivized to see what they have in young players like Clark. It wouldn't surprise me to see him up with the team after the All-Star break.
Clark feels like a natural replacement for Wenceel Perez in center field.
Braden Montgomery, OF, Chicago White Sox
Montgomery is another hitter who has found himself in this column quite often. The 23-year-old outfielder has been excellent at Triple-A since being promoted there, slashing .300/.372/.460 with three home runs and two stolen bases in 113 plate appearances.
It's encouraging to see Montgomery keep his strikeout rate in check at 24.8%, while still maintaining a rock-solid walk rate (9.7%).

While the White Sox have exceeded expectations so far, currently in the thick of the AL Wild Card race, this is still a rebuilding team that needs to give its young players a chance. At 23 years old, there's not much left for Montgomery to prove in the minors.
Currently, the White Sox have an outfield that consists of Tristan Peters, Rikuu Nishida, and Sam Antonacci. While Antonacci has been terrific, the other two aren't exactly big obstacles to playing time for Montgomery.
If Montgomery continues to hit well at Triple-A, expect him to be up soon. When that happens, you're getting a polished hitter with a high floor.
Abimelec Ortiz, 1B, Washington Nationals
Ortiz came over to the Nationals from the Rangers in the MacKenzie Gore trade. Ortiz was one of my favorite late-round targets in draft-and-hold formats, where you're looking for home runs on prospects with a path to playing time.
Ortiz has been quite solid for the Nationals at Triple-A, slashing .265/.368/.531 with 10 home runs in 190 plate appearances. You have to love the plate discipline skills, as highlighted by an 11.1% walk rate and a 19.5% strikeout rate.

Remember, Ortiz even put up a 134 wRC+ at Triple-A last year, so it's not like it's only this season where he broke out. Now 24 years old, there's really not much left for Ortiz to prove in the minors.
Even though the Nationals have exceeded expectations so far, they're still a rebuilding team. They may want to get a look at one of the key pieces of the Gore trade sooner rather than later.
We might have to wait until after the deadline, when the Nationals could ship Luis Garcia Jr. to a contender and have Ortiz replace him at first base. But there's some power upside here, especially for deeper leagues, so keep a close eye on this situation.
