The Office of the Inspector General has been called in to investigate a mix-up in a maiden race at Ellis Park, said Kentucky Racing Authority chairman Bill Street. The Kentucky Racing Authority met Aug. 16 at the Kentucky Horse Park.The mix-up happened when maiden Boggy Creek ran in place of maiden Parker Valley in a 5 1/2-furlong maiden turf race on Aug. 11. Boggy Creek finished fifth. Boggy Creek and Parker's Valley are trained by Kenny McPeek for John Parker. The horses were moved to McPeek from the barn of Tom Amoss."I want everything as squeaky clean as possible," Street said. "The authority has received divergent statements regarding what happened, and that's inappropriate. We want to maintain integrity of the highest level, and securing an independent source well versed in getting to the bottom of all the facts will help us do that."Steward Mickey Sample called the Aug. 11 mix-up a case of negligence. Sample said on Aug. 12 that hearing notices would be going out and that fines would be assessed. The authority will hear a report from the Office of the Inspector General at its September meeting, said Street.Also during its meeting, the authority voted to support the Graded Stakes Committees medication standards policy. "We're being asked to support the policy not implement the testing program," Street said.
