Race 8, Claire Simoff, ridden by Jorge Ayarza, fell over American Ivy at the three-eighths pole. Kendrick's Patsy, ridden by Martin Garcia, also tripped over American Ivy and fell. Ivy League Genius, with Baze aboard, couldn't avoid the fallen Kendrick's Patsy and went down.
American Ivy had to be euthanized. Claire Simoff, Kendrick's Patsy and Ivy League Genius were not injured. The chain reaction eliminated half of the eight-horse field.
(Midwest Blast broke down at the quarter pole in the 7th race)
