Union Rags is beginning to break the freshman sire race open, as he recorded the second Grade 1 winner of his nascent stud career when Dancing Rags captured the Alcibiades Stakes on opening day at Keeneland. She will now head to the Breeders&rsquo; Cup Juvenile Fillies, along with the stallion&rsquo;s Grade 1 Del Mar Debutante winner, Union Strike. Through Sunday, 2012 Belmont Stakes winner Union Rags, who stands at Lane&rsquo;s End, was the sire of eight winners and led the freshman sire list with earnings of $905,293. The son of Dixie Union is followed by Creative Cause at $599,416 and Dialed In at $586,358. Leapfrogging into fourth on the list was WinStar Farm freshman Gemologist, also represented by a first&#45;crop Grade 1 winner in Saturday&rsquo;s Frizette Stakes heroine, Yellow Agate. His eight winners also include impressive debut winner Thory, pointing to the Futurity on Oct. 15 at Belmont.
