November 29, 1966 – The Dodgers trade two-time batting champion Tommy Davis and outfielder Derrell Griffith to the New York Mets in exchange for outfielder Jim Hickman and infielder Ron Hunt. The Davis trade is one of many roster moves for the reigning N.L. champions. Sandy Koufax retired during the offseason after winning 27 games during the regular season because of arthritis in his left elbow. Shortstop Maury Wills was traded to the Pittsburgh Pirates because he left the team early during its goodwill tour of Japan. The Dodgers later reacquire Wills in June 1969 in a trade with the expansion Montreal Expos.
