#3 - Peace Corps
Only one horse has won four Breeders Crown finals, and that horse is Peace Corps -- with wins in 1988, 1989, 1990 and 1992. From 93 starts, Peace Corps (Baltic Speed - Worth Beein) won 62 and finished in the top-three on 81 occasions. She was named U.S. Trotter of the Year in 1989 and won divisional honours in the U.S. for five straight years from 1988 through to 1992. When Peace Corps retired, her earnings of $4,137,737 were the most for any North American trotter.
