Winchell Thoroughbreds' Magnitude (Not This Time), winner of this term's G1 Dubai World Cup and GI Stephen Foster S., worked five furlongs in a bullet 1:00.20 on Saturday over the Oklahoma dirt training track as he prepares for Saratoga's GI Whitney Aug. 8, a 'Win and You're In' for the GI Breeders' Cup Classic at Keeneland.Trained by Hall of Famer Steve Asmussen, Magnitude completed his breeze with jockey Jose Ortiz up and to the outside of GSW Tiztastic (Tiz The Law).“I'm awfully happy with him,” Asmussen said. “The conditions this morning were ideal. It was a nice, cool morning. The racetrack is in great shape. He's doing extremely well up here. Obviously, we are very excited about the Whitney.”Hall of Fame trainer Bill Mott, meanwhile, sent out reigning Horse of the Year Sovereignty (Into Mischief) and Grade I winner Baeza (McKinzie) for works over the Oklahoma on Saturday as they also prepare for the Whitney. Baeza was second after a slow start in the Foster. Sovereignty was a disappointing third as the favorite.Sovereignty, with assistant trainer Neil Poznansky up, started his work ahead of workmate Thunder Roll (Hard Spun), who closed the gap in the turn and finished up on the outside. Sovereignty kept about a half-length in front at the wire and was timed in 1:01.“It was good,” Mott said. “Very good. Felt he was on the bridle, cruising nicely.”Earlier in the morning, Baeza worked five furlongs in 1:01.20 in company with unraced 3-year-old Veblen (Tapit).“He was very good, very sharp, breezed well, galloped out good and came back good,” Mott said.The post Magnitude Leads Whitney Workers at Saratoga appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
