"It's good that everything has gone well to this point, and he's taking that next step to start facing some hitters," Miami manager Mike Redmond said on Saturday afternoon. "Hopefully, everything continues."
No timetable has been given for Fernandez's return, but it is expected to be around mid-June to the All-Star break in July.
Fernandez last pitched May 9, 2014, in San Diego. In that outing, he experienced right elbow discomfort, and a week later, he had surgery to repair a torn ligament.
Fernandez's throwing program began on Oct. 1, and he has progressed from tossing on flat ground to getting on the mound for the first time on March 1.
"He's progressing," Redmond said. "Everything has gone well so far. This is the next step."
