Sired by a champion pacer and born in 1896, Dan Patch was bred to be a racehorse. At first glance, though, his chances didn't look too good. He had long legs, knobby knees, and worst of all, a sweet disposition—not considered an asset in the hypercompetitive world of harness racing.

The National Baseball Hall of Fame credits Charles Albert Bender with inventing the slider, a curveball with extra speed. Like his patented pitch, Bender's life course was a circuitous one, beginning on the White Earth Reservation in northern Minnesota.
