Hall was promoted to Triple-A Norfolk on Thursday, Andy Kostka of The Baltimore Sun reports.
Hall began the season on the development list but has appeared at High-A Aberdeen and Double-A Bowie. Over his two starts early in 2022, he's posted a 2.35 ERA, 0.78 WHIP and 12:1 K:BB in 7.2 innings. The southpaw is one of the Orioles' top prospects and will now head to the Triple-A level for the first time.
