ETOBICOKE, Ontario – Biofuel, Canada’s Horse of the Year and champion 3-year-old filly last season, was retired on Monday. “She chipped her sesamoid, during the race yesterday,” said trainer Reade Baker, who had sent out Biofuel to finish third in Sunday’s Ontario Matron and was present when the injury was discovered late Monday morning. “She’ll stay at Woodbine, for another week, and then head down to Airdrie Stud. She’ll be bred to Majesticperfection.” Biofuel was bred in Kentucky by her owner, Brereton C. Jones, owner of the Lexington-area Airdrie Stud. A 4-year-old by Stormin Fever out of the Indian Charlie mare Ms. Cornstalk, Biofuel became a stakes winner in her fourth career outing as a 2-year-old in 2009 when she captured Woodbine’s Grade 3 Mazarine over 1 1/16 miles. After finishing a close fourth in the Breeders’ Cup Juvenile Fillies at Santa Anita, Biofuel finished in a dead heat with Negligee in the Sovereign Award voting for Canada’s champion 2-year-old filly. The 2010 voting was not close, however, as Biofuel won each of her four starts here, all in stakes, and added a second-place finish in the Grade 1 Mother Goose and a third in the Grade 1 Coaching Club American Oaks. Biofuel was just getting her campaign under way this season and was making her second start after finishing a close fourth in the Sweet Briar Too Stakes on July 1. She retires with a record line of 6-1-2 and earnings of $781,091 from 13 career starts.
