Dream leads Valerie Mastromonaco to Harpers First Ride success

From dream to purchase

A vivid dream gave Valerie Mastromonaco a starting point, but the real significance came from what followed: a mare purchase that produced winners on the track and a family that kept compounding in value. That is what makes this story resonate in racing circles, where one smart mare can shape a whole program for years.

Mastromonaco’s breeding path began almost by chance, when she imagined buying a mare in foal to Quality Road. From there, she and her partners moved into Polyester, an unraced Tiz Wonderful mare they bought for $90,000 with France and Irwin Weiner. The result was not just a single horse, but the kind of broodmare branch that can change a barn’s long-term outlook.

Harpers First Ride turned the dream into a racehorse

Polyester’s payoff arrived in Harpers First Ride, a Maryland-bred gelding foaled April 6, 2016, by Paynter out of Polyester. Equibase lists Sagamore Farm as his breeder, and his record gave the family immediate credibility beyond the breeding shed. He did not just win races, he became a graded stakes horse with a profile that reflected the patience behind his bloodlines.

His signature performance came in the Grade 3 Pimlico Special on October 2, 2020, when he won by two lengths. That victory mattered because the Pimlico Special has long carried real weight in Maryland racing, and Harpers First Ride’s win placed the mare family on a bigger stage. He later added the Deputed Testamony Stakes, the Richard W. Small Stakes, and the Native Dancer Stakes, while finishing second in the Maryland Million Classic, a resume that showed consistency rather than a single isolated burst.

Angel Cruz was a constant in that rise. Beyond the Wire noted that Cruz rode Harpers First Ride in each of his five stakes victories, a detail that speaks to how rider, horse, and placement can lock together in a successful campaign. Harpers First Ride also changed hands along the way, at one point being owned by GMP Stables LLC, Arnold Bennewith, and Cypress Creek Equine, another reminder that good horses often travel through multiple partnerships before their full value is revealed.

Why the mare family mattered beyond one winner

The deeper appeal of the story is not just Harpers First Ride’s record, but the maternal line behind him. WinStar Farm has described Polyester as a granddaughter of Treasure Chest through the stakes-winning mare Gold Treasure, which puts Harpers First Ride inside a family with established depth. That same profile notes that Polyester’s half-sister Sneaky Quiet was a two-time stakes winner and a Kentucky Oaks placer, the kind of background that signals a real producing family rather than a lucky one-off.

That matters because breeding success in racing rarely arrives by accident. A mare line that can produce stakes performers, and do it again through different branches, becomes a commercial asset as well as a sporting one. In this case, the dream was only the memorable entry point, while the pedigree supplied the proof.

The family kept producing

The story did not stop with Harpers First Ride. Another branch of the family, In a Dream, kept the line active in a way that reinforced the original instinct behind Mastromonaco’s breeding decisions. FTBOA said In a Dream was bred in Florida by France Weiner and the late Irwin J. Weiner in partnership with Valerie Mastromonaco and Tristan de Meric, extending the same collaborative approach that helped shape the earlier success.

That branch paid off most visibly in My Miss Mo, who is by Uncle Mo out of In a Dream, by Quality Road. My Miss Mo won the 102nd running of the George E. Mitchell Black-Eyed Susan Stakes, a Grade 2, on May 16, 2026 at Laurel Park, a win that carried immediate relevance because Laurel was hosting Black-Eyed Susan and Preakness weekend while Pimlico was being rebuilt. In other words, the family was still generating stakes-level results at the very moment Maryland racing was presenting itself in a transition year.

The market noticed too. Preakness and BloodHorse reported that My Miss Mo sold for $320,000 at the 2025 OBS March 2-Year-Olds in Training Sale, a price that reflects how a strong pedigree and a live update on the track can lift commercial value quickly. When a family keeps delivering both winners and sale-ring credibility, it becomes easier for breeders and buyers to believe the next foal is worth the gamble.

A racing lesson in instinct, timing, and patience

Mastromonaco’s story works because it sits at the intersection of intuition and evidence. Her dream may have provided the spark, but the lasting case for the family comes from the horses themselves: Harpers First Ride as a graded-stakes gelding, In a Dream as a productive broodmare, and My Miss Mo as a Black-Eyed Susan winner who pushed the line forward again.

That is the broader lesson for racing. The sport still rewards people who can blend instinct, partnership, and patience over a long horizon, especially in breeding where the return on one smart decision may not appear for years. In this family, the dream was memorable, but the real achievement was that the mare line kept answering it with quality on the racetrack and value in the breeding shed.
