The 1963 New York Mets season was the second regular season for the Mets. They went 51–111 and finished tenth in the National League, 48 games behind the World Series Champion Los Angeles Dodgers. They were managed by Casey Stengel. They played their home games at the Polo Grounds, the second and final season there for the Mets before moving to Shea Stadium the following season.

Offseason

Regular season

On June 14, Duke Snider of the Mets hit his 400th home run against the Cincinnati Reds. The opposing pitcher was Bob Purkey. The homer came in the 6,783rd at bat of his career. Snider became the ninth player to reach 400 homers. Along with Eddie Mathews, Snider became part of the first duo to reach the 400-plateau in the same season. Afterwards, Mets outfielder Jimmy Piersall told Snider that he could get more publicity for his 100th home run. Nine days later, on June 23, Piersall ran the bases backward after hitting the 100th home run of his career off Philadelphia Phillies pitcher Dallas Green. He was released by the Mets one month later, with that home run being the only one he hit in a Mets uniform.
