Baltimore Orioles (NL)
The Baltimore Orioles were a franchise in the National League from 1892 to 1899. Before that, they played in the American Association, then were contracted out of the league after the 1899 season, along with three other teams (the Cleveland Spiders, Louisville Colonels and Washington Senators). Ned Hanlon coached them to three straight NL Pennants, in 1894, 1895 and 1896.
They had several Hall of Famers on these championship teams including Willie Keeler, Joe Kelley, John McGraw and Hughie Jennings. They have been credited as the team that invented, or at least perfected, small ball style of play, including frequent sacrifice hitting, the hit-and-run and, of course, the Baltimore Chop.
