New York Mets legend Tom Seaver died on Monday, August 31.

The Hall of Fame pitcher passed peacefully in his sleep at the age of 75 due to complications of Lewy body dementia and COVID-19.

Seaver had served in the U.S. Marine Corps and was obtained by the Mets in a special draft lottery in 1966. He won 311 games among many other achievements over a 20-year major league career.

“Tom Seaver’s life exemplified greatness in the game, as well as integrity, character, and sportsmanship – the ideals of a Hall of Fame career,” said Jane Forbes Clark, Chairman of the National Baseball Hall of Fame and Museum. “As a longtime member of the Hall of Fame Board of Directors, Tom brought dignity and wisdom to this institution that will be deeply missed. His love for baseball history, and for the Hall of Fame, was reinforced in 2014, when he pledged the donation of his personal baseball collection to the Museum. His wonderful legacy will be preserved forever in Cooperstown.”
