The smile that has been a seemingly permanent fixture on trainer Chad Brown’s face throughout April at Keeneland, as his barn continues a strong meet and he prepares juvenile champion Good Magic for the Kentucky Derby, slipped for just an instant. After the colt turned in his penultimate Kentucky Derby breeze, which Brown termed “outstanding,” on Saturday morning at Keeneland, the trainer’s eyes grew serious as he looked ahead to the challenge of what he calls the “strongest field” he’s yet been involved with in the spring classic. "We're really confident this horse is coming into the race the right way," Brown said. "I'm confident if he continues training as he is now, he'll run the best race of his life. Whether that's good enough remains to be seen, and if he has the racing luck necessary." Good Magic, who won the Blue Grass Stakes at Keeneland in his most recent outing, led a handful of Kentucky Derby hopefuls across the state on Saturday morning. The Curlin colt, who worked solo under exercise rider Walter Malasquez, was officially credited by Keeneland clockers with a half-mile in 48 seconds flat. Daily Racing Form clocker Donald Harris reported that Good Magic got his five furlongs in 1:01.40, and galloped out in 1:14.60. "Just the way he's moving, first and foremost [is outstanding]," Brown said. "He's moving great, he's well within himself. He hit his times well, what I was looking for. It was well executed. I give my rider credit, Walter. They have good chemistry together. It's a team effort. I couldn't be happier with how he's doing." :: Kentucky Derby advance PPs are now available! Good Magic will van down the highway to Churchill Downs tomorrow and have his last pre-Kentucky Derby breeze at the Louisville track next weekend. "We'll give him a nice, full week of training all week over there, get used to the track," Brown said. “He loves it here [at Keeneland], and that’s why I chose to keep him here a little longer. I’d love to keep him here longer actually, but I just feel that it’s probably a good idea to give him one breeze over the Churchill surface. So, we’re going to go to Churchill and take it from there.” Working immediately after Good Magic was Jeff Ruby Steaks winner Blended Citizen, who went five furlongs in company with Shane Zain in 59.40 with Gary Stevens aboard. Jack Sisterson, assistant to trainer Doug O'Neill, said that Stevens, who does not have a confirmed Kentucky Derby mount, was at the barn to work Ruby third-place finisher Arawak for an upcoming engagement and got aboard Blended Citizen to "help [them] out." Kyle Frey has been aboard the colt for his most recent outings, including the Ruby win and a fifth-place finish in the Blue Grass. Blended Citizen is on the outside looking in at the Kentucky Derby field, as he sits 24th on the points list for the field limited to 20. Sisterson said the Proud Citizen colt likely will work next weekend at Keeneland before vanning to Churchill Downs early Derby week. If the colt does not make the field, he will look ahead to the Belmont Stakes, with a prep race to be determined. "From a visual standpoint, [this work] was really impressive," Sisterson said. "We're keeping to the schedule as if we're going to run [in the Derby]." Three workers at Churchill Downs At Churchill Downs, three Derby longshots – Free Drop Billy, Promises Fulfilled, and Flameaway – were out for serious breezes during the exclusive training period (7:30-7:45 a.m. Eastern) being reserved daily for Derby and Oaks horses. With the track playing perhaps a bit faster than usual, Free Drop Billy sped five furlongs in 59 seconds, a tick faster than his Dale Romans-trained stablemate Promises Fulfilled (59.20). Both went solo. “I was very pleased with all my horses’ works this morning,” said Romans. “Free Drop actually jogged a mile, galloped a mile, then worked five-eighths, and it looked like he didn’t get tired at all.” Romans said he likely will have jockey Corey Lanerie send Promises Fulfilled to the lead in the Derby. “Let's just say I wouldn’t want to be the horse in front of him trying to get ahead of him, at least if they’re trying to win,” he said. Flameaway worked outside of his Mark Casse-trained stablemate Ride a Comet when getting five furlongs in 1:00.40. Flameaway, most recently second behind Good Magic in the April 7 Blue Grass, figures among the early mix in the Derby. “I thought he worked as good as I’ve ever seen him,” said Casse. “He’s not much of a work horse, but I’ve always thought he loves Churchill Downs. He moved as well over it as ever. Huge work. We just need him to stay like this two more weeks, and we should be good.” – additional reporting by Marty McGee :: ROAD TO THE KENTUCKY DERBY: Prep races, point standings, replays, and analysis
