Good advice -thx all. Unfortunately we've just had a set back. Son's been limping off/on for past two weeks ( started after doing sprints for swim team). Pain gone after a couple days rest and never hurt when pitching or jogging or batting. He pitched the game of his life Friday night ( 6 Ks in 2 and 2/3 innings, gave up only 1 hit and no runs), but when trying to run out a grounder, on Saturday , just fell down halfway to First. Had to be carried off the field. x-rays showed two fractures in pelvic/hip area, even though he never had any trauma. Orthopedic surgeon says its common in young athletes, especially sprinters. We are going for a face-to-face with surgeon tomorrow to see if he'll need surgery. He still can't lift his left leg. If anyone has experience this , please let me know.
Thx to all.
