Lead: Expectations were high for Joyce B. Young’s 2-year-old homebred filly Caroline Thomas as the 9-to-10 favorite in Sunday’s sixth race allowance test, and she more than lived up to the challenge, splitting horses nearing the stretch and going on to score by a length over Eclipse Thoroughbreds’ pacesetter Miss Lucky Sevens in the 1 1/16 miles turf test.

Jockey Javier Castellano had the regally-bred chestnut daughter of Giant’s Causeway rated in mid-pack along the hedge down the backstretch until they found a seam and shot through as she scored her second victory in three career starts for veteran trainer Barclay Tagg. The victory marked the third on the afternoon for Castellano.

“I’m just glad he was on her,” said Tagg of Castellano after the race. “He rode her in her first race when she was second (Belmont Park on Sept. 16). It’s uncanny how he stays calm and cool until he finds the right spot to get clear. Her dam (Bit of Whimsy) was a Grade 1 winner and we hope this filly will be a stakes horse too, which probably will be the next step for her.”

Caroline Thomas broke her maiden in her second start at Aqueduct on Nov. 4 before shipping south to Tagg’s winter headquarters at Palm Meadows. She is the first foal out of Bit of Whimsy, winner of the Queen Elizabeth II Challenge Cup (G1) at Keeneland and other stakes for the same owner-breeders and Tagg.

Caroline Thomas paid $3.80 for $2 as she was timed in 1:39:66 over the ‘firm’ course. Lee Lewis’ Casual Elegance finished third in the field of nine, 3 ¾ lengths behind the runner-up.
