La Rascasse (f, 3, Authentic–Hallawallah, by Candy Ride {Arg}), a 'TDN Rising Star, presented by Hagyard' debut winner by a head going seven furlongs at Keeneland Apr. 11, backed up that performance with a smart victory in Saturday's $175,000 Monomoy Girl S. at Churchill Downs.The 9-5 second-choice was always traveling like the winner beneath Axel Concepcion in second in this two-turn debut, took over while in hand on the far turn and had 2 1/2 lengths over Point of Reference (Upstart) at the wire.La Rascasse becomes the 10th stakes winner for Authentic. Hallawallah is a daughter of Maryfield, who annexed the 2007 GI Ballerina Stakes, then took the inaugural and very sloppy running of the Breeders' Cup Filly & Mare Sprint. Hallawallah is also represented by the juvenile colt Mambo Man (Mandaloun) and a yearling colt by McKinzie.Lifetime Record: 2-2-0-0.Owner: Resolute RacingBreeder: Bill Klislt (KY)Trainer: William WaldenLa Rascasse captures Race 9, the Monomoy Girl Overnight Stakes, at Churchill Downs! pic.twitter.com/aekYLxxk5O— Churchill Downs (@ChurchillDowns) June 13, 2026The post ‘Rising Star’ La Rascasse Stays Perfect in Monomoy Girl Stakes appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
