Garcia was optioned to Triple-A New Orleans on Friday, Andre Fernandez of the Miami Herald reports.
Although Garcia earned a call-up in 2016, he didn't see any game action and hasn't pitched above Double-A in his career. With Miami's multiple offseason pitching acquisitions, it was unlikely the 24-year-old was going to win a spot in the rotation, so he'll head to Triple-A and work his way towards a call-up.
