For the second time this year, Travis Dunkelberger has ridden seven winners in one day's race card.The 23-year-old jockey won seven races Wednesday at Timonium, a five-eighths-mile track just north of Baltimore. On March 30, he also won seven races at Charles Town in West Virginia after having won one that afternoon at Pimlico."It's hard to get excited about winning while you're riding." Dunkelberger said. "You have to take it race by race. You win a race, you put it behind you and go to the next race."Five of Dunkelberger's winners Wednesday came with horses trained by Dale Capuano. Because Capuano is serving a 15-day suspension for a clenbuterol positive, his father, Phillip L. Capuano, was listed as trainer of record."I don't know anybody better than [Travis] is, especially at a five-eighths-mile track," said Dale Capuano, who watched the races from the grandstand. "He's got the most experience riding these small tracks."Dunkelberger has spent the year near the top of the win standings for jockeys. He has cut back riding at Charles Town so he can ride regularly in Maryland.
