JUPITER, Fla. -- Marlins ace Jose Fernandez took another step in his rehab from Tommy John surgery on Sunday, when the right-hander threw a short bullpen session off the mound for the first time since last May.
Fernandez, who was diagnosed with a torn UCL after his eighth start last season and had surgery May 16, warmed up on flat ground for several minutes Sunday morning before heading to the mound at the Roger Dean Stadium complex. He threw 10 warmup pitches, then fired 15 fastballs to bullpen coordinator Jeff Urgelles as pitching coach Chuck Hernandez watched from the side.
