I'll be back as soon as my elbow will let me . And if anything... I have about a year to learn how to throw lefty ;)You haven't seen the last of me Miami, I promise you that."
Fernandez, the reigning National League Rookie of the Year, was 4-2 with a 2.44 earned run average over eight starts before the injury.
The 21-year-old right-hander will be sidelined for at least 12 months. The surgery will take place on Friday in Los Angeles.
