The Astros selected Munoz with the eighth pick of the Rule 5 Draft on Wednesday.
Munoz, 25, actually has plenty of MLB experience, unlike most Rule 5 picks. The hard-throwing righty logged 83.2 innings in the majors for Miami in 2024 before spending 2025 in the Cardinals organization, working primarily as a reliever at Triple-A. Munoz had a 3.28 ERA, 1.32 WHIP and 76:30 K:BB in 57.2 innings last season at Triple-A.
