A three-horse spill in the second race yesterday marred the final live card run at Pimlico Race Course in 1993.
The 4-year-old filly, So Sly, ridden by Frank Douglas, broke down, starting a three-horse pileup which also included Joe Rocco on Kels Clever Choice and Freddy Castillo on Russian Vixon.
Douglas and Castillo escaped serious injury.
But Rocco, who has had his share of misfortune this year, hurt his lower back.
However, he was given the go-ahead by doctors to compete later on the card and won the seventh race aboard Shelter Bay.
Two of the three horses involved in the spill apparently are all right, but So Sly was was euthanized. She was the 10th horse at the 36-day Pimlico meet that was destroyed because of a serious leg fracture or racing accident.
Live racing starts tomorrow at Laurel Race Course, which has a 1 p.m. daily post time.
