Hughes, Joba, Kennedy Are Workout Freaks. The Journal News piece accentuates the extracurricular running, calisthenics and muscle exercises the three young pitchers have implemented under the supervision of Andy Pettitte.

Suddenly I feel pretty cool as I remember running a 6:26 mile in high school.
