Saying the Kentucky Derby Presented by Yum! Brands (gr. I) is in the past, trainer Dan Hendricks is ready to forge ahead in Saturday's Preakness Stakes (gr. I) at Pimlico Race Course. "Throw out the Derby and go on," Hendricks said. "Right now he's (Kentucky Derby winner Barbaro) the number one guy and we're trying to knock him off. This is about hoping I'm good enough to beat him."Brother Derek, who arrived at Pimlico Wednesday, had been stabled with trainer Wally Dollase since finishing fourth, beaten 9 1/2 lengths, in the Kentucky Derby Presented by Yum! Brands (gr. I). Brother Derek, owned by Cecil Peacock, galloped once around Pimlico Thursday morning under assistant trainer Francisco Alvarado."He's a fresh horse, and very full of himself," Hendricks said of the son of Benchmark. "He handled the track good, so whatever happens Saturday, I can't use the track as an excuse."Brother Derek, with jockey Alex Solis, will break from post five as the 3-1 second choice on the morning line. Barbaro and Sweetnorthernsaint, the only other Derby runners to start in the second leg of the Triple Crown, will break from post six and seven, respectively."It's a good thing about the short field, we'll be all together," Hendricks said. "It should be a really fun race."While Hendricks said the sport is in need of a Triple Crown winner, he is not ready to offer up the title."I think it would be great for the sport, and I would hate to see him (Barbaro) not win," Hendricks said. "But make no mistake about it, we're in it to win it."
