Baseball Hall of Famer and two-time Cy Young Award winner Gaylord Perry, a master of the spitball who wrote a book about using the pitch, died Thursday. He was 84.

Perry died at his home in Gaffney at about 5 a.m. Thursday of natural causes, Cherokee County Coroner Dennis Fowler said. He did not provide additional details.

"Gaylord Perry was a consistent workhorse and a memorable figure in his Hall of Fame career," MLB commissioner Rob Manfred said in a statement, adding, "he will be remembered among the most accomplished San Francisco Giants ever ... and remained a popular teammate and friend throughout his life."
