LOUISVILLE, Ky. - Bold Start got Robby Albarado started on his next 1,000 wins when he prevailed Saturday at Churchill Downs in the $112,600 Aristides, the race that followed Albarado notching the 4,000th victory of his career. Bold Start, a 5-year-old horse owned by Larry Carroll, got a terrific stalking trip under Albarado before winning by 2 3/4 lengths over Semaphore Man in the 21st running of the Aristides, the second of two Grade 3 stakes on an 11-race Saturday card. Bold Start paid $10.80 as third choice in a field of 10 older horses after finishing six furlongs in 1:09.04 over a fast track. "This horse has knocked on the door quite a few times in graded races," said winning trainer Ken McPeek. "He's been nothing but professional, and he sure showed that today." A half-hour before the Aristides, Albarado became just the 56th jockey in North American racing history to win 4,000 races when he guided favored Keertana ($5.20) to victory in a $49,485 turf allowance. Albarado, 35, began his riding career in 1990. He was joined in a brief post-race winner's circle ceremony by his wife, Kimber, and three children. In the Aristides, longshot Garifine led early, with Bold Start and Semaphore Man always ready to strike. Down the stretch, Bold Start proved clearly best, striding clear for his ninth victory from 31 career starts. Knights Cross rallied late to be third at 35-1, another three-quarters of a length behind Semaphore Man. Sok Sok, the 9-5 favorite, was another length back in fourth. Bold Start, by Jump Start, earned $66,321 on Saturday to boost his career bankroll to $528,810. * Earlier Saturday, Hightap ($14) rebounded from a subpar effort to upset odds-on Luster in the 35th running of the $111,500 Dogwood Stakes. With Shaun Bridgmohan giving an excited fist-pump passing under the wire, Hightap finished 3 1/4 lengths before Luster after getting a textbook stalking trip. "She really put it all together today," said Bridgmohan, who had ridden the gray Tapit filly in all four of her prior starts, including maiden and allowance wins at Fair Grounds. Hightap was returning from an 11-week layoff. Scott Blasi, assistant to trainer Steve Asmussen, said Hightap had trained well after recovering from a foot bruise apparently incurred in a last-place finish in her previous start, the Honeybee Stakes at Oaklawn Park. Perfect for You rallied late to be third, another 2 1/2 lengths behind Luster in a field of nine 3-year-old fillies. Hightap completed the one-turn mile in 1:35.78.
