Rabeeba, Curlin filly, wins debut at Los Alamitos for Baffert

Rabeeba did not waste time turning a rich pedigree into a result. The Curlin filly broke her maiden in a 6 1/2-furlong special weight for 3-year-old fillies and mares at Los Alamitos on June 19, finishing a sharp first start by 1 1/2 lengths in 1:16.38 for owner Michael Lund Petersen, trainer Bob Baffert and rider Ricardo Gonzalez.

That kind of debut matters because it came from the type of horsemen and bloodlines that usually announce themselves quickly. Rabeeba was a $750,000 purchase at the 2024 Keeneland September Sale, where Stone Farm consigned her, and the market paid for more than a pretty page. She is by Curlin and out of Chatham, a mare who has already produced eight winners from 10 foals to race, a record that makes a first-out win feel less like an upset than the next step in a productive family.

The female line has already generated names that carry weight beyond one maiden race. Air Force Blue is in the family as a black-type winning half brother, while Shea D Summer and Trophy Chaser add more stakes substance to the page. Rabeeba’s younger full brother, Stone Aged, gave the family another commercial marker when Juddmonte bought him for $450,000 at the 2026 OBS Spring Sale. That is the kind of resume that keeps a filly on the radar after a debut: classy enough to be expensive, proven enough to project upward, and now fast enough to justify the attention.

For Baffert, the win fit a familiar pattern at Los Alamitos, where he has long used maiden races to launch better horses quickly. A debut like this does not just put a filly in the winner’s circle; it can change the conversation around where she belongs next, whether that means another step in allowance company or a move toward stakes company if she keeps moving forward.

The same bloodstock-driven theme ran through the day with Collado Hueco, the first foal out of Dunbar Road, making his own debut in a maiden special weight at Belmont at the Big A. The Into Mischief colt, bred in Kentucky by White Birch Farm and foaled Feb. 15, 2023, came from a mare who earned $1.70 million, won the 2019 Alabama Stakes, and missed by a nose in the 2020 Breeders’ Cup Distaff. Taken together, those first starts were reminders that the right maiden race can serve as an opening statement for horses bred to matter fast.
