Three top fantasy baseball prospects - Joshua Baez, Walker Jenkins, Kade Anderson - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.
During the first half of the season, fantasy managers have seen the importance of stashing prospects as playersl ike Payton Tolle, Konnor Griffin and Gage Jump have all flashed high-end upside once reaching the big leagues.
In this piece, we will spotlight three of the top prospects in the minor leagues who could be worth stashing after the All-Star break.
Should fantasy managers stash these high-end prospects? Let's dive in!

Joshua Baez, OF, St. Louis Cardinals
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 82 G, .250/.321/.573, 16 2B, 28 HR, 14 SB
It has been a couple of weeks since we last checked in on Cardinals outfield prospect Joshua Baez. Although he has cooled off at the plate recently, his overall performance still warrants a promotion to the majors.
Through 82 games, Baez is slashing .250/.321/.573 with 28 home runs and 14 stolen bases, good for a 127 wRC+.
Simply put, if I could stash only one hitting prospect right now, Baez would be my choice. The biggest thing standing in the way of his promotion is a crowded St. Louis outfield.
The Cardinals’ current corner outfielders, Jordan Walker (142 wRC+), Lars Nootbaar (117 wRC+), and Nelson Velazquez (146 wRC+), have all performed well this season, making it difficult for him to be called up.
However, the designated hitter spot has been less consistent. Bryan Torres has struggled recently, striking out in 40% of his last 15 plate appearances while posting a 71 wRC+.
While Velazquez brings a different skill set as a left-handed hitter and Baez bats from the right side, Baez has shown he can handle both left-handed and right-handed pitching. Here is a breakdown of his Triple-A splits so far this season.
On the field, the concern with Baez is obvious: the strikeouts. He is currently striking out close to 30% of the time while posting a 36.21% chase rate and a 74.88% zone-contact rate.
With that said, when Baez does make contact, the results are loud. He owns an absurd 20.6% barrel rate and a .529 expected slugging percentage (xSLG).
Overall, the 23-year-old has checked every box to earn a promotion to the majors. He should debut by early August, and once he does, his combination of power and speed will make him a must-add in all fantasy formats.

Walker Jenkins, OF, Minnesota Twins
Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 38 G, .277/.386/.440, 10 2B, 13 HR, 7 SB
Like his Triple-A teammate Kaelen Culpepper, Walker Jenkins has struggled to stay healthy this season. However, after returning from a sprained AC joint in his shoulder, he quickly picked up where he left off.

When healthy, he has looked like the player scouts envisioned when the Twins selected him fifth overall in the 2023 draft. The 21-year-old left-handed hitter brings an impressive combination of bat-to-ball skills, strong plate discipline, and developing power.
He also consistently controls the strike zone, posts strong walk rates, and has the offensive foundation to become a middle-of-the-order contributor. From a fantasy perspective, Jenkins will eventually have top-20 outfielder upside.
So when should managers expect Jenkins? Right now, the timeline remains uncertain, but the trade deadline could change everything. In 2025, Minnesota traded away several players at the deadline to cut payroll.
With the team sitting below .500, the Twins could once again prioritize the future over short-term competitiveness. Their current outfield situation may also eventually create an opening for Jenkins.
Byron Buxton is currently on the injured list with a hip injury, which opened the door for Alan Roden to receive a promotion from Triple-A. However, Roden probably isn't a long-term solution for the club.
Last year, he struggled during his first taste of the majors, hitting just .191/.261/.294 across 153 plate appearances with the Blue Jays and Twins.
While Roden has looked much better in Triple-A this season, posting a 134 wRC+ over 38 games, he is unlikely to block one of the organization's top prospects.
As platoon bats, Austin Martin (101 wRC+) and Trevor Larnach (131 wRC+) have both been productive this season, but either could be moved before the trade deadline.
If you have the roster space, Jenkins is worth stashing in 15-team leagues right now. Once he earns a promotion, he should be rostered in all 12-team formats.

Kade Anderson, SP, Seattle Mariners
Current Level: AA
Availability: 5% rostered
2026 AA Stats: 72 2/3 IP, 1.36 ERA, 0.69 WHIP, 108 SO, 10 BB
Even though Kade Anderson took a brief step back (by his standards) at Double-A this past week, the budding ace remains the clear No. 1 stash target among pitching prospects. On July 3, Anderson allowed two runs (for the second straight game) over six innings, walking none and punching out eight.
Over his last two outings (11 innings), the southpaw has now allowed four runs while posting an incredible 18:2 K:BB. Despite this brief step back, the southpaw continues to boast ridiculous numbers during his first professional season.
Overall, over his first 14 starts as a professional (all at Double-A), the former LSU superstar has posted a 1.36 ERA and a 0.69 WHIP. During this noted stretch, the left-hander has struck out 108 hitters with solid elite command, walking only 10 batters. He has kept the ball in the yard quite well, allowing just four total long balls.
Additionally, among these 14 starts, Anderson has allowed more than two runs in only one start, a career-worst five-run effort against North Arkansas on May 15.
While his upside remains the highest among any pitchers on this list, his path to the majors makes him a frustrating pitcher to roster for fantasy. While those in formats with N/A spots should continue to leave him there for the remainder of the season, those needing to use a bench spot should think twice before picking up the lefty.
Currently, the Mariners are operating in a five-man rotation on the MLB roster with one of their six "starters" serving as a bulk reliever. This has kept all six pitchers thoroughly involved in the team's game plan and has not created any path for Anderson to debut.
Back in June, a report also stated that the former No. 3 overall pick is still not in the team's "immediate" plans, further putting his ETA into question. While he will need to wait for an injury (and likely two), Anderson needs to remain above the names on this list when looking at upside.
Even if he were to make only a handful of starts (or bulk outings), he could very well post near-perfect ratios with elite strikeout numbers and become a must-start pitcher.
Kade Anderson has made 14 starts this season.
