Road less traveled: Red Sox RHP prospect Blum capping unlikely first pro season in the desert

Boston Red Sox pitching prospect Harry Blum is finishing his first professional season in the Arizona Fall League after working at a grocery store earlier this year. After pitching in college for Division III Luther College and Division II Augustana University, Blum trained in Arizona while working shifts at Safeway before signing with the Red Sox in February 2026.

Blum spent the 2026 regular season working primarily as a multi-inning reliever for Single-A Salem, recording 76 strikeouts across 66 innings. In his recent Arizona Fall League appearances, the 6-foot-7 right-hander has showcased an expanded pitching arsenal that features a mid-90s fastball, a newly developed cutter, a slider, and a changeup.
