He was also the manager of the Red Sox during the 1930 baseball season. Wagner was born in Harlem, New York, in September 1880. He began his baseball career playing for the Waverly Club in the New York State League in 1901.

Wagner and Harry Hooper were the only players to play on all four of the Red Sox World Series championship teams of the era. Wagner was considered to be a valuable infielder while playing with the Red Sox and was reputed to have "an exceptionally powerful and accurate throw." He was also known to block the basepaths with his "exceptionally big" feet.
