John McGraw was the fiery third baseman of the Baltimore Orioles in the 1890s, but he achieved much more recognition as an innovative, autocratic field manager. In his 31 years at the helm of the New York Giants, Little Napoleon's teams won 10 pennants, finished second 11 times and took home three World Series trophies. He ranks second all-time with 2,840 wins. As a player, he was credited with helping to develop the hit-and-run, the Baltimore chop, the squeeze play and other strategic moves.
