One of the biggest questions throughout Orioles spring training was answered Sunday afternoon when the club optioned DL Hall to minor league camp. The left-hander had a slow start this spring with a lower back injury — a setback that prevented Hall, the organization’s No. 2 pitching prospect, from being built up as a starter in time for the beginning of the season. The Orioles had two choices: Ramp him up as a starter in the major league bullpen, where he ended the 2022 campaign, or send him to Triple-A to go through his workload progression in Norfolk.
