“I’ve been down in Tampa since the day after I had my surgery,” Severino said. “I do arm bike, dumbbell exercises, and I just follow the routine that [trainers] Timmy [Lentych] and Alfonso [Malaguti] plan out for me. I spend an hour and half with them in the trainer’s room before I move into the gym, every day, five days a week.
“Things have been progressing well. I’ve been making steady progress -- lifting, doing exercises. Since three months ago -- I think when I first had my surgery -- I feel way better. I’m doing everything I need to do right now so that I can start throwing this summer.’’
That was in May 2020. He has since started his throwing program. Optimistically he could be ready in time for ST 2021, all depends on his progress in the rehab.
