Vesia is part of the Marlins' 60-man player pool, Craig Mish of SportsGrid.com reports.
The 24-year-old southpaw has thrived as a reliever in the minors ever since the Marlins selected him in the 17th round of the 2018 draft. He utilizes a deceptive delivery and a plus changeup to flummox minor-league hitters, but lacks the high-end velocity (sits in low-90s) typically associated with late-inning arms.
