Baum (undisclosed) made his 2021 debut in the rookie-level Arizona Complex League on Aug. 13 and has logged three appearances in total, covering 5.1 innings while giving up five earned runs on five hits and four walks while striking out five.
The 23-year-old was delayed to begin the season while recovering from an unspecified injury, but he's starting to get ramped up again in the ACL. Baum tossed three innings in his most recent outing Saturday, and he shouldn't have to wait much longer to receive a promotion to Low-A Stockton.
