ETOBICOKE, Ontario - Biofuel ($48.20) circled five wide into contention on the far turn before drawing away for a surprisingly easy victory in the at Woodbine on Saturday.\nThe Grade 3 Mazarine often helps to determine the Canadian champion 2-year-old filly, but Negligee may have secured that award already after her victory in Saturday's Grade 1 Alcibiades at Keeneland. Biofuel finished fourth behind Negligee in the Aug. 15 Ontario Debutante Stakes and was coming off a seventh-place finish on turf in the Grade 3 Natalma Stakes. \n"She didn't like the turf at all," said Eurico Da Silva, who rode Biofuel in both the Ontario Debutante and the Mazarine. "When she got back to the Poly, she ran great."\nResentless set honest fractions in the 1 1/16-mile event, while Biofuel trailed the eight-horse field on the backstretch. Biofuel loomed into contention on the far turn and then blew by favored Cascading at the top of the stretch en route to a 4 1/2-length win in a time of 1:44.47. \nBay to Bay finished a clear second, and Witch's Coven rallied to outrun a fading Resentless for third. \nBiofuel, trained by Reade Baker, banked $150,000 for owner/breeder Brereton Jones.
