Doing Great is undefeated in two starts, including a 10-1 upset in the $100,000 Maryland Million Lassie earlier this month. But based on her Beyer Speed Figures, Doing Great may have a difficult time keeping her perfect record intact when she makes her Delaware Park debut in Wednesday&rsquo;s $50,000 White Clay Creek Stakes for 2-year-old fillies going six furlongs.\r\nFour of Doing Great&rsquo;s five rivals in Wednesday&rsquo;s overnight stakes own a superior Beyer to both the 57 she recorded while defeating maiden claimers in her career debut at Monmouth Park and the 65 she was awarded for her half-length score in the Oct. 2 Maryland Milliion Lassie.\r\nThe best last-race Beyer belongs to another Laurel Park-based filly, Juanita, who like her uncoupled stablemate Doing Great, is trained by Mike Trombetta. Juanita has put together solid back-to-back races at Penn National and Laurel, defeating maiden special weight company and first-level optional $50,000 claimers by a combined 10 1 /4 lengths. Her most recent win on Sept. 29 was worth a 74 Beyer, but she will be racing beyond 5 1/2 furlongs for the first time Wednesday.\r\nYet another Laurel shipper, Red&rsquo;s Round Table, looks dangerous if she can regain the form she showed two starts ago when winning a first-level optional claimer at her home track by 6 1/2 lengths and earning a 73 Beyer. Last time out, she was ambitiously spotted in the $95,000 Sorority at Monmouth and stopped in midrace after expending valuable energy acting up inside the gate.\r\nSpring Jump won back-to-back starts at Penn National, collecting a 68 Beyer for a first-level allowance win, before a dull effort on the synthetic Tapeta surface at Presque Isle Downs in the $100,000 Presque Isle Debutante.\r\nThe Monmouth-based Sopchoppy comes off the best race of her six-race career, a two-length score that earned a 69 Beyer against first-level allowance runners.\r\nThe field is rounded out by Mis Vizcaya, who returns to Delaware, where she won back-to-back starts in June, following losses in the $94,000 Colleen at Monmouth and the $100,000 Miss Shenandoah at Charles Town.
