Dontrelle Wayne Willis, nicknamed "the D-Train", is an American former professional baseball pitcher. A left-hander, he played in Major League Baseball for the Florida Marlins, Detroit Tigers, Arizona Diamondbacks, and Cincinnati Reds. Willis was notable for his success during his first few years in the major leagues and for his unconventional pitching style, which included a high leg kick and exaggerated twisting away from the batter. He was named the 2003 National League Rookie of the Year and won the World Series in the same year.
