On April 13, 1967, New York Mets right-hander Tom Seaver made his major league debut against the Pittsburgh Pirates at Shea Stadium. The Mets won the contest, 3-2, though Chuck Estrada and not Seaver was the winning pitcher.
It was a positive start to the career of Seaver, who would go on to become the greatest Met in franchise history, and one of the best starting pitchers in the history of baseball.
Seaver had been signed by the Mets back in April of 1966. He was initially drafted by the Los Angeles Dodgers, who opted not to sign him, and then by the Atlanta Braves, whose contract with Seaver was ultimately voided after violating an NCAA rule about players signing pro contracts after the college season had begun.
