The Providence Grays went 84–28 during the 1884 season to win the National League championship. The team started out with two main pitchers, Charles "Old Hoss" Radbourn and Charlie Sweeney. After Sweeney jumped to the Union Association in mid-season, Radbourn pitched most of the Grays' remaining games and led the team to the pennant. Radbourn won 60 games by himself, setting a Major League Baseball record that has never been broken.
