The Cardinals placed Hicks (elbow) on the restricted list last week after he informed the team that he was opting out of the 2020 season.
The transaction removes Hicks from the Cardinals' 40-man roster, giving the team some more flexibility before it begins its season July 24. Per Mark Saxon of The Athletic, Hicks' choice to skip out on the 2020 season wasn't totally motivated by concerns about the health risks he may have faced pitching amid the COVID-19 pandemic as a Type 1 diabetic. Instead, the 23-year-old disclosed that he recently dealt with inflammation during his throwing program as he worked back from his June 2019 Tommy John procedure. The extra time off to rest should allow Hicks to report at full health for 2021 spring training, at which point he could re-emerge as the Cardinals' top closing candidate.
