AUBURN, Wash. - Atta Boy Roy shattered Emerald Downs's six-furlong track record Sunday, running the distance in 1:07 en route to a 10 3/4-length victory in the $50,000 Chinook Pass Sprint and a possible berth in the Breeders' Cup Sprint.\nRidden by Ricky Frazier for trainer Valorie Lund, the 4-year-old by Tribunal led throughout, carving fractions of 21.20, 43.20 and 55 seconds. The previous track record was 1:07.40, set by Starbird Road in 2006 and equaled by Atta Boy Roy in his Emerald Downs debut June 6, and the state standard had been 1:07.20, set by Grey Papa at Longacres in 1972.\nThe Chinook Pass Sprint was one of seven stakes races for statebreds on Washington Cup Day.\nAtta Boy Roy, who paid $2.40, won for the second third time in four starts at the current meeting and earned $27,025 for owners Roy and Ellie Schaefer or Port Orchard, Wash. He has seven wins in 15 starts with career earnings of $134,325.\n"He's the fastest thing I've ever been on; he's just a true train," Frazier said of Atta Boy Roy, who finished fifth in the Grade 3 Longacres Mile in his previous start after setting the fastest six-furlong split (1:07.60) in the race's 74-year-history. \nLund said Atta Boy Roy would race next in the Grade 1, $300,000 Ancient Title Stakes at Santa Anita on Oct. 11. Part of the Breeders' Cup's Win and You're In program, the Ancient Title gives Atta Boy Roy an opportunity for automatic berth in the Grade 1, $2 million Breeders' Cup Sprint on Nov. 7, also at Santa Anita.\n"This horse is incredibly fast," Lund said. "I told Ricky two things: Win the race, and don't take too much out of him."\nIn other Washington Cup races:\n* Wasserman ($3.20) rallied for a 1 1/4-length victory over Scalding Passion in the $50,000 Muckleshoot Tribal Classic, running 1 1/16 miles in 1:42. It was the first victory in eight 2009 starts for Wasserman, who won the 2008 Longacres Mile en route to horse-of-the-meet honors. Owned and trained by his breeder, Howard Belvoir, Wasserman increased his lifetime earnings to $518,549. Regular rider Jennifer Whitaker was up Sunday.\nBelvoir said Wasserman, a 7-year-old, would be turned out for the winter and likely return to Emerald Downs in 2010.\n* Koala Beach ($3) posted an eight-length victory in the $50,000 Dennis Dodge Stakes for 2-year-old colts and geldings, running 6 1/2 furlongs in 1:15.60 under Gallyn Mitchell.
