Gin Gin needed Shimmering Allure to take a step back if she was to win the $100,000 Busanda Stakes on Saturday at Aqueduct. Shimmering Allure obliged.  While Gin Gin sat on the rail, tracking pacesetting Princess Mayfair, Shimmering Allure spun her wheels over a muddy, sealed racing surface, first plunked between horses, then coming outside on the turn for a run that ultimately went nowhere. Up front, Princess Mayfair, who was clear through a half-mile in 47.93, was not going down without a fight, but Gin Gin edged to a half-length lead at the stretch call and won by one length.   It was the third Aqueduct victory in a week for trainer Brad Cox, who won the Ladies with Comparative and the Jerome with Drumroll Please on Jan. 6. And the Busanda, for 3-year-old fillies, marked the first stakes win for Gin Gin, a Calumet Farm homebred by the Calumet stallion Hightail and out of Before You Know It, by Hard Spun. Racing in Kentucky, Gin Gin had been beaten about seven lengths in her stakes debut and about eight lengths in her most recent start, the Grade 2 Golden Rod. On Saturday, she benefitted from having to beat only four rivals, a task made much easier when the best of them, Demoiselle runner-up Shimmering Allure, failed to show up.  :: Bet the races with a $200 First Deposit Match + FREE All Access PPs!

Stretching out a half-furlong after two 1 1/16-mile tries, Gin Gin ran 1 1/8 miles in 1:53.31, including a final furlong in a glacial 14.49, and paid $7.60 as the second choice.  “I was a touch concerned if she would want to go a mile and an eighth and she put my doubts to rest today with her performance,” Cox told NYRA publicity. “She’s a very good-looking filly and has always trained well in the mornings.”  Trevor McCarthy gave Gin Gin an ideal trip in his first start aboard the filly.  Princess Mayfair was making her first start on dirt following three races over Woodbine’s Tapeta surface and acquitted herself solidly, finishing nine lengths clear of Shimmering Allure. Most of All trudged home fourth while Class Act barely picked up her feet, though she still earned two Kentucky Oaks qualifying points. The first four across the finish got 20,10,6, and 4 points.   Cox said Gin Gin would stay in New York and likely go on to the Gazelle Stakes in April.   :: Want to learn more about handicapping and wagering?
