ARCADIA, Calif. - The best horse crossed the wire first in the Grade 2 on Saturday at Santa Anita. However, Megahertz racked up two rivals at the head of the stretch in the mile and an eighth turf stake for fillies and mares, and it took stewards just five minutes to disqualify the odds-on favorite from first and place her last for interference, which resulted in Katdogawn inheriting the win in the $150,000 race.
