Fantasy Baseball Prospect Risers - Rookies to Stash and Top Performers for Week 7

May 10, 2026

Jeremy's top fantasy baseball prospect risers, breakouts with big upside for Week 7 of 2026. He analyzes top MLB rookies and call-ups to stash who are surging.

Welcome to the week 7 edition of the top prospect performers. In this weekly piece, we'll break down three standout prospects who are dominating in the minor leagues. While some may be further away from the majors than others, they're all bound for fantasy relevance at some point. Whether they warrant an immediate add or just someone to monitor in dynasty leagues, it's important to stay up to date on the recent prospect news.

There has been a flurry of promotions over the recent weeks, with the latest call-ups being Bryce Eldridge, Robby Snelling, Ryan Waldschmidt, and Spencer Jones. Eldridge, Snelling, and Waldschmidt were making regular appearances in this piece, so now we get to dig a little deeper into guys that you may not have heard much about up until this point.

This week, we'll discuss one familiar pitcher along with two outfielders who are tearing it up in Triple-A. Adding the right prospect at the right time could propel your squad to a fantasy championship, so without further ado, let's get into it.

Kade Anderson, SP, Seattle Mariners

Mariners No. 2, Overall No. 14

The last time I wrote about Kade Anderson in this piece was two weeks ago, when I mentioned that he looked simply too good for Double-A. He’s made two starts since then and has continued to look nearly unhittable, with his most recent gem coming on Friday night. 

He allowed one run on two hits and one walk over 5 ⅔ innings while striking out nine, which followed up his previous start of eight strikeouts over 5 ⅔ shutout innings. The 21-year-old is now 3-0 through six starts with a 0.60 ERA, 0.67 WHIP, and 47 strikeouts through 30 innings. It’s not often you see an ERA lower than WHIP, but he has just been that absurdly good at keeping runs off the board.

The youngster recorded a whopping 22 whiffs on 75 pitches in his most recent outing, and it’s worth wondering how many more starts he’ll have at the Double-A level. It’s clear he’s ready for at least Triple-A, but realistically, he’d be on the verge of a major league call-up if he played for most teams other than the Mariners.

With Bryce Miller set to return in the upcoming week, Seattle is already in a tight situation. With Logan Gilbert, Bryan Woo, and George Kirby already established as frontline starters and Luis Castillo seemingly stuck in a rotation spot due to his veteran pedigree, they may be forced to send Emerson Hancock to the bullpen, despite his success. 

This leaves little room for Anderson with the big league club, unless their staff suffers multiple injuries at once. That’s why the top prospect isn’t an absolute must-stash at this stage, but I do think he’s way too good not to get a chance at some point this season. Those five starters mentioned above haven’t had the cleanest bill of health as a unit over the past couple of years, and at some point, Castillo will need to do better than a 6.00 ERA to justify keeping his job if the Mariners find themselves in a close playoff race.

Verdict: Stash in leagues with deep benches for a likely late-season promotion

Cole Carrigg, OF, Colorado Rockies

Rockies No. 6, Overall N/A

Cole Carrigg was gaining some steam as a top prospect last season, before disappointing in his first taste of Double-A with a .237/.316/.394 slash line. His strikeout rate ballooned to 27%, but he did steal 46 bases and hit 15 homers in 123 games, doing enough to maintain a hopeful outlook for his future. 

The Rockies decided to bump him up to Triple-A to start 2026, and the youngster is having the best season of his professional career. Heading into Saturday, he has hit safely in nine straight games, with five being multi-hit performances.

The 24-year-old is slashing .366/.426/.522 with two home runs, 27 RBI, 32 runs, and 21 steals in only 34 games. What’s even more encouraging than his counting stats is that he’s cut his strikeout rate all the way down to a miniscule 14.1%. 

The power will likely be limited at the major league level, but luckily for Carigg, he’ll eventually have the honor of playing half of his games at Coors Field. Some decent pop can go a long way in Colorado, and his elite speed could make him a very valuable fantasy asset. He’s swiped 133 bags in 308 career minor league games, showing no signs of slowing down. 

The Rockies have several uninspiring names shuffling around their outfield, including Jake McCarthy, Jordan Beck, and Brenton Doyle, so it could be Carrigg’s turn before you know it. He’s also played 10 games at shortstop this season, so Colorado may already be thinking about additional ways to get him in the lineup in the future.

Verdict: Monitor for a later-season promotion

Henry Bolte, OF, Athletics

Athletics No. 5, Overall N/A

Henry Bolte had a modest 2025 in Double-A and Triple-A as a 21-year-old, slashing .284/.385/.427 with nine home runs and 44 stolen bases in 114 games. The power took a step back from previous years, but he was battling a nagging wrist injury that could have very likely sapped that strength. He took care of it with offseason surgery, and he's looked like one of the best hitters in the minors so far in 2026.

The youngster's great season culminated on Friday night, when he went 5-for-5 with two homers, a triple, and two doubles, and he's now batting .576 through seven games in May. On the season, he's slashing an impressive .329/.401/.604 with 10 homers and 16 stolen bases, while he's cut down his 28.9% strikeout rate from 2025 down to a much more manageable 22.8%.

Henry Bolte had a MASSIVE game yesterday in Triple-A.

5/5, 2 2B, 3B, 2 HR

Season: 167 PA, .329/.401/.604, 18 XBH, 10 HR, 16 SB, 10.2% BB, 22.8% K

Bolte's dynasty stock is 📈📈#Athleticspic.twitter.com/y8Cd3T5KxD

It's easy to see that the 22-year-old has a tantalizing combination of power and speed, which could make him a standout fantasy option, especially in the A's hitter-friendly Sutter Health Park. This is a level of production that can't be ignored at the Triple-A level for long before warranting a promotion, although the A's will need to figure out a way to make it work.

They have a logjam of young talent in the outfield, although Lawrence Butler and Carlos Cortes are both platoon players. It could be easy to see Bolte becoming an immediate improvement over Colby Thomas and Darell Hernaiz as a short-side platoon option, but they wouldn't want to promote him only for him to sit out most games.

Whether they finally decide to give up on Butler, Cortes finally cools off, or they suffer an injury, Bolte looks like he's putting himself in line to be the next one promoted. It's not a must-stash situation in standard leagues, but definitely monitor it closely, as an imminent promotion is much more likely for him than the first two prospects mentioned in this piece.

Verdict: Stash in AL-only leagues
