Hall was optioned to Double-A Bowie on Monday, Rich Dubroff of BaltimoreBaseball.com reports.
Hall made just one appearance in spring training prior to his demotion, striking out a pair of batters in one scoreless inning of relief work. He'll begin the season at Double-A, where he posted a 3.13 ERA and 1.03 WHIP to go along with a 56:16 K:BB across 31.2 innings a year ago. Although he'll begin 2022 with the Baysox, reports emerged earlier in the spring that the southpaw could progress through Baltimore's farm system quickly with the possibility of making his big-league debut at some point during the upcoming campaign.
