Godolphin Stables' Tempera, the champion 2-year-old filly of 2001, was euthanized the evening of April 28, said Tom Albertrani, assistant to trainer Saeed bin Suroor. Tempera had already been removed from consideration for the May 3 Kentucky Oaks.The filly became ill April 26 at Churchill Downs, and was sent to Hagyard-Davidson-McGee veterinary clinic near Lexington. She had a fever, but her condition worsened."Her condition got really bad," Albertrani said. "It developed into colitis, and then laminitis. It's hard to believe that her condition went so bad in 24 hours. They couldn't do anything to help her."Tempera won last year's Breeders' Cup Juvenile Fillies at Belmont Park. The victory helped her bag an Eclipse Award.Imperial Gesture will now be Godolphin Racing's lone representative in the Kentucky Oaks, a 1 1/8-mile classic for 3-year-old fillies.
