DEL MAR, Calif. - The first race at Del Mar on Sunday was declared no contest after Thatcher, a 3-year-old filly, broke down on the backstretch and bothered four of the other six runners in the one-mile turf race.
According to California Horse Racing Board rules, the stewards reserve the right to cancel a race if interference occurs that affects the majority of the horses. The stewards reached the decision to declare a no-contest after a lengthy inquiry.
