“Catfish” Hunter was diagnosed with ALS, better known as Lou Gehrig’s disease, in 1998. The man who had become famous for his legendary pitching arm quickly lost the use of both arms due to the neurological disease.

Hunter, who pitched for the New York Yankees from 1975-79, died in 1999 at age 53.

Although the family returned to their native North Carolina after Catfish’s time in the Bronx, the Hunters were regular fixtures at Yankee Stadium for annual events like Old Timer’s Day.
