He is a classic late-blooming, undrafted arm with a fun name who has carved out a solid niche as a high-minors reliever rather than a high-profile prospect. He is not ranked among the Mets’ top prospects but has drawn positive notice for his performance relative to his background.Professional Career and Stats

Pitching RepertoireAvailable scouting notes describe a solid three-pitch mix suited to relief work:

• Fastball — Tops out at 95 mph (pre-draft reports); often described in the low-to-mid 90s. Some MiLB materials list a sinker as a primary offering.
• Cutter — Noted in organizational reports alongside the sinker.
• Slider — A reliable secondary that generates whiffs.
• Changeup — Mentioned in pre-draft Baseball America notes as another secondary that produces swings and misses.

Overall profile from available reports: A physical righty with enough velocity and secondary stuff (especially the slider/changeup pair) to miss bats, plus decent command for a reliever. He profiles as a potential organizational depth or middle-relief arm rather than a high-leverage closer prospect at this stage, but his 2025 dominance and size give him a path if the stuff continues to play up.

In short, Hoss Brewer is a fun-name, hard-throwing undrafted success story who has performed well enough in the Mets system to earn High-A (and brief Triple-A) looks as a reliever. His repertoire centers on a mid-90s fastball/sinker-cutter combination paired with a slider and changeup.
