3 Impact Fantasy Baseball Prospects To Stash - Kade Anderson, Liam Doyle, Henry Bolte

May 16, 2026

Three top fantasy baseball prospects - Kade Anderson, Liam Doyle, Henry Bolte - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.

Finding high-impact prospects on the air can propel your team to a fantasy championship. While some prospects do not earn the call until the second half, they are worth stashing ahead of time as their impact could be immense.

In this piece, we will spotlight two of the top pitching prospects in the sport and one hitting prospect who recently earned the call to the big leagues.

Should fantasy managers stash these high-end prospects? Let's dive in!

Kade Anderson, SP, Seattle Mariners

Current Level: AA
Availability: 10% rostered
2026 AA Stats: 30 IP, 0.60 ERA, 0.67 WHIP, 47 SO, 5 BB

It didn't even take a full calendar year for Kade Anderson to go from a top-5 pick in the draft to arguably the top pitching prospect in baseball. In his first six starts for Double-A Arkansas, Anderson has recorded a pristine 0.60 ERA, a 0.67 WHIP, a 4.7% walk rate, and a 44.3% strikeout rate. Anderson's 39.6% K-BB rate is the third-best mark in the minors, and his 1.61 FIP is the second-lowest mark among pitchers with at least 20 innings.

It's not like the Mariners have a dire need for pitching at the moment, as they have one of the top rotations in baseball. But as we know, pitching injuries pop up all the time. In my eyes, it's not a matter of if Anderson gets called up this season, but when and how early. Honestly, I think Anderson could handle big league hitters today.

With Snelling now up with Miami, Anderson joins Thomas White as the top pitching prospects to stash in redraft leagues.

Liam Doyle, SP, St. Louis Cardinals

Current Level: AA
Availability: 5% rostered
2026 AA Stats: 21 IP, 6.43 ERA, 1.52 WHIP, 26 SO, 7 BB

Although Liam Doyle has not yet dominated the minor leagues, he possesses all the tools to make an immediate fantasy impact once he reaches the majors. The left-hander was selected fifth overall in the 2025 MLB Draft after a dominant season at the University of Tennessee. During his final college season, Doyle recorded a school-record 164 strikeouts in just 84 1/3 innings while posting a 10-4 record and a 3.20 ERA.

Much of that success came from his elite 70-grade fastball. Doyle’s heater has touched 100 mph and consistently sits in the mid-to-upper 90s during games. Beyond the velocity, the pitch features excellent vertical ride, comes from a difficult high release point, and explodes through the top of the strike zone. Even at the major league level, it’s the type of fastball that can miss bats, even when hitters know it’s coming.

Doyle also features a strong secondary mix that includes a slider, curveball, and a splitter/changeup that works especially well against right-handed hitters. The main concern in his profile is inconsistent command, though many young pitchers improve with more major league experience. The bigger question is whether there is a clear spot for him in the Cardinals’ rotation, and eventually, there will be.

St. Louis’ current rotation includes Matthew Liberatore (4.86 SIERA), Andre Pallante (4.51 SIERA), Kyle Leahy (4.44 SIERA), Dustin May (4.22 SIERA), and Michael McGreevy (3.97 SIERA). None of these starters has separated themselves from the group, which makes a Doyle promotion later this summer increasingly realistic. This is especially true as the Cardinals continue to focus on their long-term rebuild.

With pitching injuries rising across MLB, Doyle should already be on the radar in 15-team leagues and becomes a strong speculative add in 12-team formats once he is promoted. However, that call-up may not come until the All-Star break or early August, unless there is an injury in the starting rotation.
