Rose to Gold and Touch Magic, two fillies that train at Calder Casino & Race Course, finished first and second on Saturday in the $500,000 Delta Downs Princess Stakes (Grade 3) at Delta Downs in Vinton, La.

Rose to Gold took the lead coming around the final turn and held off the fast-closing Touch Magic to win by a half-length in the one-mile dirt stakes that has one of the country’s biggest purses for 2-year-old fillies. Rose to Gold was ridden by Paco Lopez and finished in 1:39.38.

“My heart was bouncing around in a lot of places,” said Sal Santoro, the trainer of Rose to Gold, who watched on a racing channel from his home in Davie. “But she [Rose to Gold] is very competitive, and I was confident she could hold off the other Calder filly who ran a tremendous race.”

The victory was the third in four starts for Rose to Gold, who already was on many analysts’ top-10 lists of 2-year-old fillies.

Her other wins were by runaway margins in the Lindsay Frolic Stakes and Brave Raj Stakes at Calder.

Rose to Gold was the 5-2 second choice in the Delta Princess and Touch Magic, at 25-1, was the second highest price in the nine-horse field. The $2 “Calder exacta” paid $141.40.

Salamera, also stabled at Calder, finished sixth. Madame Cactus, the 3-2 favorite who is based in Louisiana, finished fourth.

Rather than making the trip to southwestern Louisiana, Santoro put Rose and Gold under the temporary care of trainer Juan Arias.

Arias trains Decisive Moment, a 4-year-old colt, who finished fourth behind winner Prospective in Saturday’s $150,000 Delta Mile at Delta Downs.

Jesus Rios rode both Rose to Gold and Touch Magic in all of their previous races.

The mother-son team of Kathleen Amaya and Raffaele Centofanti owns Rose to Gold. Both live in South Florida.

Santoro said he plans to run Rose to Gold in Gulfstream Park’s 2013 stakes series for 3-year-old fillies, including the Davona Dale (Grade 2) on Feb. 23.
