Macho Uno, winner of last year's Breeders' Cup Juvenile (gr. I) and the leading candidate for champion 2-year-old honors, is scheduled to arrive at trainer Joe Orseno's barn at Gulfstream Park Friday, where he'll begin preparing for the classics.Danny Vella, farm manager of owner Frank Stronach's Adena Springs in Ocala, said Macho Uno has been galloping and swimming on a regular basis, and is just about ready for a half-mile work. "With the Breeders' Cup, there no longer is enough time to lay a horse off properly, so we've been training him lightly and trying to give him as much of a freshening as possible," Vella said. "He hasn't been let down. He's just been having a nice change of scenery, while keeping fit. He's done some swimming and we've been grazing him in a little pen. He's put on 70 pounds, but in the shoulder and rear end, not in the belly. He still has an attitude, but he's shown me more signs of maturity. What makes him so special is his efficiency of stride. You can see how efficient he is when he gallops."Macho Uno, a son of Holy Bull, also captured the Grey BC at Woodbine last year and was third, beaten a neck, in the Hopeful Stakes (gr. I) coming off a maiden score.Vella also reported that Preakness (gr. I) winner Red Bullet is recovering from foot problems suffered last year, and should be ready to run by the summer. Breeders' Cup Filly & Mare Turf (gr. I) winner Perfect Sting, who is the frontrunner for champion filly and mare turf honors, is being kept in training and will point for a 2001 campaign. No races have been mapped yet.
