York also managed the Grays for part of the 1881 season, and in total managed the Grays for 96 games, with 56 wins and 37 losses, for a winning percentage of .602.[5] In their second season, the Grays were managed by shortstop and Baseball Hall of FameerGeorge Wright.[1] Wright led the team to a record of 59 wins and 25 losses for a winning percentage of .702 in 1879, winning the National League pennant.[1][6] Wright left the team to join the Boston Red Caps, managed by his brother Harry Wright in 1880.[6][7] In 1880 and 1881 the Grays employed a total of five different managers, including York's second term and 32 games managed by Hall of Famer John Montgomery Ward.[1][8]
In 1882, Hall of Famer Harry Wright, George Wright's brother, became the Grays manager, and George Wright rejoined the team as their shortstop.[1][7][9] Harry Wright managed the team for two seasons, winning 110 games and losing 72.[7]Frank Bancroft became the Grays' manager in 1884 and managed the team to record of 84 wins and 28 losses and a winning percentage of .750, winning the Grays' second National League pennant behind the strength of Charles Radbourn's record 59 pitching victories.[1][10][11] The Grays also won the World Series in 1884; however the 19th century World Series was a very different event from the current World Series, which began in 1903.[12] The 19th century World Series was considered an exhibition contest between the champion of the National League and the champion of the American Association.[13] The Grays defeated the American Association champion New York Metropolitans in the 1884 World Series winning three games and losing none.[12] Bancroft managed the team again for their final season as a Major League team in 1885 with less success.[1] Bancroft finished with an overall managerial record with the Grays of 137 wins and 85 losses, for a winning percentage of .617.[14]
Bancroft managed the most games in Grays' history, 224, and his 137 wins and 85 losses are also the most in Grays' history.[2] George Wright has the highest winning percentage of any Grays' manager, with .702.[2] Three Grays' managers, Ward and the Wright brothers, were elected to Baseball's Hall of Fame.[15]

a Although the Grays won the tournament called the World Series in 1884, the 19th century World Series was a very different event from the current World Series, which began in 1903. The 19th century World Series was considered an exhibition contest between the champion of the National League and the champion of the American Association. The Grays defeated the New York Metropolitans in the 1884 World Series winning all three games.[12][13]
