Hang in there. Seems like an amazingly long journey but before he knows it, he'll be picking up a ball...and then throwing off a mound...and pitching in his first game back with a fresh arm. Son is 2 years post TJ in his redshirt freshman year. Stronger mentally and physically than he ever was...and has a drive like never before.
This will just become another chapter of his story...with an ending you will be very proud of watching develop. Best to your son.
