Mission Brief on Thursday became the fastest 2-year-old trotter in harness racing history when she won her division of the International Stallion Stakes in 1:50.3 at The Red Mile in Lexington.
Driven by Yannick Gingras for trainer Ron Burke, the filly won by 16 lengths over Gold Cora in the $80,550 event.
Her time was only two-fifths of a second off the fastest time by any female trotter, set by 7-year-old Giant Diablo in 2007 at The Red Mile.
Mission Brief, who set a world record for the third time this year, has won six of nine races and $313,315. She went off stride in her three losses.
"She's been here for two weeks and she's been very good here mentally," Burke said. "It's never been a soundness thing with her, it's always been getting her mentally sound for the race. She's a super freaky filly and Yannick has done a super job with her. She could have gone another direction, but Yannick has been very patient with her and today was the calmest I've seen her."
Other International Stallion Stakes division winners were Jimmy Takter's Flirting Filly, Julie Miller's Livininthefastlane, and George Ducharme's Concentration.
