The Maryland Jockey Club cancelled Saturday's $75,000 Dave's Friend because 12 trainers who nominated their horses declined to enter and race against Pimlico-based Disco Rico, one of the top sprinters in the country. "It is disappointing, but these things happen in racing," said Lou Raffetto, Chief Operating Officer for the Maryland Jockey Club. "We tried every avenue, but nobody had any interest in testing Disco Rico." Disco Rico, a 4-year old Maryland-bred, has won eight of 14 career starts including a standout victory performance in his last race, the $200,00 Maryland Breeders Cup on the Preakness undercard. The only remaining stakes race in the 13-day Mini-Meet is the $125,000 Straight Deal Breeders Cup on Saturday, Aug. 18. Thirteen horses have been nominated, including Laurel Park-based Xtra Heat, one of the top three-year old fillies in the country with 14 wins and two-second place finishes in 17 career starts. Thirteen of her victories have been of the stakes variety.
