Seaver spent 12 seasons with the Mets, winning 198 games, prior to spending six years with the Cincinnati Reds, three with the Chicago White Sox, and one with the Boston Red Sox, before retiring after the 1986 season at the age of 41.

He finished his career with a record of 311-205, a 2.86 ERA, and 3,640 strikeouts, while winning three Cy Young Awards, and being named an All-Star on 12 separate occasions.

With one no-hitter and five one-hitters to his credit, to go along with 231 complete games and 61 shutouts, Seaver earned election into the Hall of Fame in his first year of eligibility in 1992 with 98.8 percent of the vote, the highest election percentage at that time.

Voted into both the New York Mets and Cincinnati Reds Halls of Fame, Seaver's No. 41 was retired by the Mets in 1988.
