The Brewers’ farm system continues to shine, even after several key prospects have graduated in recent years. The addition of three new names to this list highlights the depth and talent still in the pipeline.
No. 13 – 2B Josh Adamczewski
Selected in the 15th round of the 2023 draft, Josh Adamczewski signed with Milwaukee after forgoing a commitment to Ball State. Despite missing time in 2024 due to injury, he impressed with a 156 wRC+ across the Arizona Complex League and Low-A Carolina. He’s off to an even better start in 2025.
Adamczewski’s standout trait is his bat. With the potential for a plus hit tool, he consistently drives the ball to all fields with authority. According to Chris Clegg of Dynasty Dugout, Adamczewski made mechanical adjustments to his stance and hand positioning aimed at improving his timing and reducing his ground ball rate—early results have been very encouraging.
While not a major power threat, Adamczewski’s ability to elevate and pull the ball gives him more game power than expected. As a teenager, he posted exit velocities up to 108 MPH and has demonstrated impressive gap-to-gap power, racking up doubles and triples.
Defensively, Adamczewski projects best at second base due to limited arm strength, though his instincts and effort are definite assets. His hustle—particularly in backing up plays at first—has already led to a few extra outs for the Mudcats early in the 2025 season.
No. 15 – RHP Bishop Letson
Drafted in the 11th round in 2023 and signed away from a Purdue commitment, Bishop Letson made an immediate impact in 2024, posting a 3.13 ERA in his age-19 season. He’s taken another step forward in 2025.
Letson features a four-pitch arsenal, highlighted by both a four-seam and a two-seam fastball in the 92–95 MPH range. The four-seamer has touched 98 MPH and is particularly effective thanks to elite extension (7.5 feet), allowing the pitch to play up in velocity. His two-seamer generates 15–16 inches of arm-side run, while the four-seamer carries well, making it a weapon at the top of the zone.
Among his secondaries, Letson’s slider stands out. It sits in the low 80s with sharp glove-side break and has proven effective for both strikes and whiffs. His changeup, thrown in the mid-80s with solid fade, is still developing but flashes average-or-better potential when consistent.
The most notable development for Letson in 2025 has been his improved command. He’s nearly halved his 10.5% walk rate from 2024, a promising sign for his long-term projection. If he can maintain these gains and handle a full workload, Letson profiles as a legitimate future big-league starter.
