Houston Astros Prospect Profile: Alonzo Tredwell
Alonzo Tredwell – RHP
HT/WT: 6’8″/245 | Bat/Throw: L/R | School/Country: UCLA | DOB: 05/08/02
Overview:
Tredwell is an imposing presence on the mound, measuring 6’8″ and 230 pounds. A second-round pick in 2023, he had a strong college career at UCLA, finishing with a 2.83 ERA and 113 strikeouts over 92.1 innings. The right-hander features a mid-90s fastball that can touch 96 mph, complemented by a sharp slider as his primary secondary pitch. His fastball plays especially well up in the zone, generating plenty of whiffs due to its carry.
Tredwell has unfortunately missed all of the 2026 season dealing with an undisclosed injury.
Tredwell dealt with some injuries early in the minors logging just 57 innings in his first full season. In 2025, the right-hander turned things around. He started the year in Single-A and had a 3.94 ERA with 52 K in 48 innings. He was promoted to High-A where he had a 3.68 ERA with 30 K in 29.1 innings. Tredwell was dominant to finish the season striking out 40 batters over 22.2 innings with a 3.18 ERA in Double-A.
