The Darley Stable-owned Swither's first career victory was an impressive 10-length romp Saturday in the $200,000 Delaware Park NATC Sorority. Ridden by Aarron Gryder, the 2-year-old daughter of Anees, in her second start, covered the six furlongs in 1:11.80 over a fast main track. The 1-to-2 favorite in the field of eight, Elke, with Abel Castellano astride, ran second. It was another 1 1/2 lengths further back to Undeniable Queen, with Daniel Velazquez aboard, in third. Swither, a New York-bred trained by Tom Albertrani, returned $9, $3 and $2.10 as the second choice. "I think after her last race that just really tightened her up," said Albertrani. "She got a little tired in her last start at Saratoga and she just seemed a lot more aggressive since that race and a little more on her game today." Swither battled Elke for the early lead and began to shake loose after a half-mile, widening her advantage through the lane."With two races, she had some experience under her and she just seemed after her last race to put her mind more on business."Elke returned $2.20 and $2.10 and Undeniable Queen's show was $2.10.
