His older brother Harry Wright managed both Red Stockings teams and made George his cornerstone.

At some times during the war, both Wright brothers played for the venerable Gothams, the second-oldest baseball team after the Knickerbockers.

Baseball's recovery from the American Civil War was far advanced in greater New York City (always untouched by the military conflict), as the leading clubs played more than 20 National Association of Base Ball Players (NABBP) matches, the Gothams 11.

At the December annual meeting, the first in peacetime, NAABP membership tripled, including isolated clubs from as far as Fort Leavenworth, Kansas and Chattanooga, Tennessee.

The Union of Morrisania, now in the New York borough of the Bronx, were another charter member of the first Association, but one that moved toward professionalism in the postwar years, as the Gothams did not.

In 1867, he joined the Nationals of Washington, D.C., the oldest club in that city, whose approach to professionalism was arranging government jobs, mainly with the Treasury.

Next year he returned to the Unions for the association's last officially all-amateur season and moved permanently to the shortstop position.

When the NABBP permitted professionalism for 1869, Harry augmented himself and four incumbents with five new men including his brother George, who was highest paid at $1400 for nine months.

With some personnel changes, the Boston Red Stockings won the other four NA pennants, dominating so severely in 1875 that they helped provoke a new league.

Boston trailed badly in the first NL season after the defection of its Big Four western players to Chicago, but rebounded to win again both 1877 and 1878.

[5][6] In December 1890, Wright and three friends obtained a permit and chopped nine holes in the frozen ground of Boston's Franklin Park, playing two rounds.

)[9] Wright & Ditson became a major seller of golf clubs; early U.S. Open champion Francis Ouimet worked at the store while pursuing his amateur career.

George Wright served on the 1906–1907 Mills Commission that—despite a complete lack of historical evidence—determined that Cooperstown, New York was the birthplace of baseball.

[10]) Wright accompanied the United States contingent to the 1912 Summer Olympics in Stockholm, Sweden where demonstrations of baseball, involving American track and field athletes and a team of Swedish players, were held.
