Scouting Report
Updated May 19, 2026
AJ Blubaugh is a 25-year-old right-hander for the Houston Astros who has been a key contributor to the bullpen since his late April debut. Over 29 big-league appearances (including 3 starts), he has posted a 3.22 ERA over 58⅔ innings with a 5-3 record and 3 saves. Blubaugh has undergone a significant mechanical transformation, moving from an unconventional submarine knuckleball delivery with multiple arm angles to a more conventional and consistent delivery. His velocity has improved substantially, reaching 95-96 mph by winter 2021 after hitting 90 mph in summer ball. He was drafted in the 7th round by Houston and was ranked as the system's 3rd prospect with a 45 FV when he reached the majors.
