Santa Anita Park reopened its inner-exercise track in Arcadia on Friday and instituted new rules after 21 horses died over the last two months at the park.

Racing at the park has been suspended indefinitely after the number of Thoroughbred deaths started to skyrocket since late December. The park also announced the track would ban race-day medication and the use of riding crops.
