Longines Kentucky Oaks (gr. I) winner Untapable, a perfect four-for-four in 2014, on July 21 put in her final breeze for the $1 million William Hill Haskell Invitational (gr. I).
Her connections plan to send the 3-year-old filly to Monmouth Park July 24 in advance of the July 27 race in which she will face males.
Ron Winchell's homebred daughter of Tapit worked an easy four furlongs in 50.28 under exercise rider Mike Callaham on the Saratoga Race Course's Oklahoma training track.
"So far everything is good. She cooled out good," said Darren Fleming, assistant to trainer Steve Asmussen. "She's on schedule to ship in on Thursday morning."
Untapable, racing in all graded stakes this season, has won her outings by a combined 31 lengths and notched the Kentucky Oaks (gr. I) and Mother Goose Stakes (gr. I) in her previous two starts. When she starts in the Haskell, it will be the filly's first try against males, but Asmussen is no stranger to crossing that line.
In 2009 he sent Kentucky Oaks and Preakness Stakes (gr. I) winner Rachel Alexandra to Monmouth for the Haskell, and she cruised to a six-length victory on her way to Horse of the Year and champion 3-year-old filly honors. Now Untapable will try to become the third filly to win the Haskell and join Hall of Fame member Serena's Song (1995) in the record books.
"It worked out pretty well for Rachel," Fleming said. "There are no compunctions about sending her to the Haskell."
