Pete Frates, a 27-year-old baseball player from Beverly, Mass., was in the best shape of his life. But a wayward pitch to the wrist and the lingering weakness that followed marked the start of a tragic turn.
"There were no broken bones, so they started to look for nerve damage," Frates said.
Six months of tests would reveal something far worse than a damaged nerve. He discovered in March that he has ALS, a deadly neurological disease that usually strikes people in their 50s and 60s.
