The first time Trickle of Gold made an appearance on a Maryland racetrack, she unspooled her blazing speed and ran away from the Toddler Stakes field last December at Pimlico. Unfortunately, she had dumped her rider in the post parade and gone on a wild chase with the outriders before being corralled and scratched from the race.

It wasn't the only time Trickle of Gold rid herself of the human on her back, but the 3-year-old daughter of Formal Gold has grown up since then and begun to look like one of the fastest fillies on the East Coast.

On her best behavior and teamed with Delaware-based riding ace Jeremy Rose yesterday at Laurel Park, Trickle of Gold blasted out of the starting gate, repelled two stiff challenges and ran away to a three-length victory in the Grade III $150,000 Safely Kept Breeders' Cup.

Trickle of Gold, trained at Delaware Park by Michael Gorham, has effortlessly won her past four starts and now proven she can defeat horses that have raced in top company.

"She ran through her [allowance] conditions so easily; this was just like the next step for her," Gorham said after Trickle of Gold had won the six-furlong race in a swift 1 minute 10.45 seconds.

Trickle of Gold always had shown talent, racing in a stakes race before she had even broken her maiden. Her antics as a 2-year-old, however, got her nothing but a long vacation away from the track.

"She dumped the rider and ran off [in the Toddler Stakes], and we shipped her to Gulfstream and she did the same thing," Gorham said. "Usually the ones who are a problem are the cheaper ones. Once they have a bad experience, they think it's supposed to happen again. . . . It was a matter of getting her in the right spot and getting her head screwed on."

Gorham, from Canton, Mass., turned Trickle of Gold out on a farm outside of Boston and let her mature. When she returned to racing this past June, her speed was intact, and after a second-place finish she won her next three starts by a combined 253/4 lengths before trying the Safely Kept.

When the gate opened, Trickle of Gold rolled right out to the lead, hounded on the outside by 31-1 long shot Lady Dynasty in the field of five. After putting down that upstart with a half-mile run in 44.85 seconds, Partners Due, the only local horse in the race, advanced into contention on the outside entering the stretch.

Favored Maddalena, a multiple stakes winner for top trainer Todd Pletcher in New York, had struggled to keep up early but also began to rally.

Neither could catch the winner.
