Roderick Edwin Kanehl was an American second baseman and outfielder in Major League Baseball who played his entire career with the New York Mets (1962–1964). Beloved by Mets fans, his attitude was exemplary for a team that lost a modern-era record 120 games in its inaugural season. Kanehl hit the first grand slam in Mets history on July 6, 1962 at the Polo Grounds.
