Former New York Yankees pitcher Mel Stottlemyre is "fighting for his life" according to his son Todd in a Facebook posting.
Stottlemyre announced in 2000 he was diagnosed with multiple myeloma.
Stottlemyre, now 75, was a three-time 20 game winner for the Yankees and was a five-time All-Star.
He was their pitching coach for four World Series titles.
In 2015, the Yankees honored Stottlemyre with a plaque in Monument Park.
