Billy Cowan, who had hit 19 home runs with the Cubs in 1964, was acquired by the Mets in exchange for George Altman prior to the 1965 season. He went 0-4 in his Met debut on Opening Day 1965 and went on to hit just .179 for the season splitting time between 2nd base, shortstop and the outfield. The highlight of his brief Met career came on June 28 and 29 when he hit home runs in back to back games. He would hit 3 homers on the season with 9 RBIs before the Mets traded him to the Milwaukee Braves on August 5th in exchange for two players to be named later. The Braves would eventually send Ernie Bowman and Lou Klimchock to compete the trade.
He would play seven more seasons splitting time between the majors and the minors before retiring after the 1971 season.
While with the Mets Cowan wore number 3.
