AUBURN, Wash. – Noosa Beach capped a record-setting meeting with an easy victory Sunday in the $50,000 Muckleshoot Tribal Classic, one of six stakes for statebreds on Washington Cup Day at Emerald Downs. The 4-year-old by Harbor the Gold won for the sixth time in seven starts in 2010, and set an Emerald Downs record with his fifth stakes victory; he had been one of 10 horses to record four stakes win in a season at the suburban Seattle track, which opened in 1996. Ridden by Ricky Frazier for owner Jeff Harwood and trainer Doris Harwood, the owner’s wife, Noosa Beach ran one mile in 1:35 and returned $2.40 as a prohibitive favorite in a six-horse field. Frazier settled Noosa Beach into a striking position behind pacesetter Siberian Cocktail before moving him to the front around the second turn. Noosa Beach gradually increased his advantage from there, winning by 2 3/4 lengths. Wasserman rallied to finish second, with He’s All Heart another half-length back in third. They were followed by Margo’s Gift, Siberian Cocktail, and Scalding Passion. Noosa Beach’s season included victories in the six-furlong Seattle Handicap, the one-mile Budweiser Handicap, the 1 1/8-mile Mount Rainier Handicap, and the Grade 3 Longacres Mile. He earned $26,180 Sunday, increasing his 2010 earnings to $225,930 and his lifetime bankroll to $366,770. He has won 10 of 16 starts. “The plan today was to just keep him clear,” Frazier said. “I knew that everyone was trying to beat him, so I just wanted to get him in a good spot. He did it so easily. If any horses came close, he would have just blown them away. He was much the best today. It just feels awesome to ride a horse like this. I just wish the season wasn’t almost over.” In other Washington Cup races: * Sis’s Sis ($9.40) rebounded from a last-place showing behind Zenovit in the Washington Oaks to beat that rival in the one-mile, $37,000 John and Kitty Fletcher Stakes for 3-year-old fillies.
