OKLAHOMA CITY, OK—MAY 11, 2025—Rainbow Of Diamonds had not had a race in 2025 but came into Remington Park sparkling like the Hope Diamond in her trial for the Grade 2, $300,900 Heritage Place Oaks.

When the seven-race trial series ended early Sunday night, she was easily the fastest qualifier.

The Heritage Place Oaks is a 400-yard race set for Saturday, May 31, the final night of the Remington Park spring season. The event is part of an all-stakes evening, Champions Night, with the richest purses of the season on the line, topping $2 million overall.

Rainbow Of Diamonds, a 3-year-old Oklahoma-bred filly by champion sire Apollitical Blood, from the Tres Seis mare CC Seis, didn’t blink an eye after a layoff from Oct. 27, 2024, to May 11, 2025.

Trainer Victor Rodriguez-Flores had her set on ready, and jockey Francisco Calderon had the pedal to the metal in this speedy trial. She raced in the second trial of seven and put up a time of :19.286, earning a speed-index of 105 over the fast track.

Rainbow of Diamonds did that with a 13-mph tailwind on an 80-degree day in Oklahoma City. The wind died down to under 10 mph in the later trials.

Calderon was tied on and burst down the track when Rainbow of Diamonds won by a visually impressive 2-1/2 lengths. She was sent off at 4-5 odds as the prohibitive favorite and paid $3.80 to win, $3 place, and $2.10 to show.

Rainbow Of Diamonds won for the fourth time in her career, racing for owner Valeriano Racing Stables (Sammy Valeriano) of Odessa, Texas, for the first time in this Heritage Place Oaks trial. As a 2-year-old, she competed for Xcel Farms of Asher, Oklahoma, and trained Ed Hardy.

Rainbow Of Diamonds has now started nine times with four wins, and two thirds for earnings of $78,893. She was a $22,000 purchase from the Ruidoso Select Yearling Sale in 2023. Her breeder in Oklahoma was Danny Joe Miller.

Rainbow Of Diamonds has shown an affinity for Remington Park. As a 2-year-old last year, she won a Heritage Place Futurity trial but broke 10th in the $1 million final, never giving herself a shot at winning that cornerstone race, finishing ninth.
