LOUISVILLE, Ky. &ndash; Rosemary Homeister Jr. is the fifth and most recent woman to ride in the Kentucky Derby, having finished 13th aboard 43-1 shot Supah Blitz in the 2003 running. That was little more than a cameo appearance at Churchill Downs for Homeister, who has been based at a number of East Coast tracks since she began riding professionally more than 18 years ago, but she&rsquo;s working on changing that.\r\nHomeister has been riding regularly at Churchill for the first time this fall, much to her delight.\r\n&ldquo;I absolutely love it here,&rdquo; she said. &ldquo;This is a big plus in my career.&rdquo;\r\nAfter the first 6 of 21 fall programs, Homeister already had 4 wins from just 13 mounts, and she will be trying to build on those numbers Thursday when she gets a leg up from trainer Mark Hubley on Your Round, one of the main contenders in the featured ninth race. Although still eligible for the second-level allowance conditions governing the 1 1/16-mile turf race, Your Round has earned an eye-popping $366,967 from 25 career starts.\r\n&ldquo;I worked him last week in Lexington, and he impressed me as a big, long-striding, classy horse,&rdquo; said Homeister, who at age 38 has more than 2,400 career wins, second only to Julie Krone among female riders. &ldquo;I&rsquo;d have to think he&rsquo;ll have a good shot in there.&rdquo;\r\nYour Round will break from post 2 in the $52,000 feature, one of two allowances on a 10-race Thursday card. He could be the second wagering choice behind Asphalt, a stakes-seasoned 3-year-old who most recently was third in the Grade 3 Hawthorne Derby. Julien Leparoux will be aboard Asphalt for trainer Eddie Kenneally when breaking from post 6 in a field of 11, which includes one also-eligible.\r\nAlso in the feature-race lineup is Advice, winner of the Grade 2 Coolmore Lexington at Keeneland in April 2009. Advice did not run particularly well in a recent comeback following a 15-month layoff.\r\nIn the earlier allowance (race 8), Flourish and Silver La Belle look like the top contenders among nine fillies and mares competing in a $50,000 turf route under a first-level restriction. Flourish will have Kent Desormeaux riding for the high-profile tandem of Juddmonte Farms and trainer Bill Mott.\r\nFirst post Thursday is 12:40 p.m. Eastern.
