Three stakes winners whose recent form has gone sour will try to regain some confidence against slightly easier competition in Monday&rsquo;s featured ninth race at Parx Racing.\r\nThe 3-year-old Vindy City, winner of the Miss Preakness in May; Miss Blue Tye Dye, who collected six stakes victories against Pennsylvania-breds between August 2008 and October 2009; and Indy&rsquo;s Alexandra, winner of the $100,000 Three Ring as a 2-year-old nearly three years ago, are among eight fillies and mares set to race 6 1/2 furlongs in a third-level optional $40,000 claimer.\r\nCollectively, the trio have combined to lose 20 straight races while competing mainly at higher levels than Monday&rsquo;s race.\r\nOf the group, Vindy City is the most lightly raced with a 3-for-6 lifetime record, highlighted by her one-length score at 3-2 odds in the six-furlong Miss Preakness at Pimlico on May 14. In two subsequent stakes starts, Vindy City finished ahead of just one horse while beaten a combined 22 3/4 lengths.\r\nDropping into a non-stakes for the first time since January, Vindy City has a license to improve, but it must be noted that her trainer, John Servis, is just 2 for his last 21 with horses returning from a break of 61 to 180 days in races between 6 1/2 and seven furlongs, according to DRF &rsquo;s Formulator.\r\nThe 6-year-old Miss Blue Tye Dye has dropped eight in a row since winning the 1 1/16-mile Cozy Lace at Philadelphia Park a year ago. She is one of two horses in for the optional $40,000 tag.\r\nMiss Blue Tye Dye was claimed for $22,000 by Penn National-based trainer Dave Geist in mid-July. She shortens up in distance and drops in class following two dull efforts in restricted stakes. Geist is just 7 for 88 with horses coming back in less than 30 days switching from routes to sprints.\r\nIndy&rsquo;s Alexandra has lost 10 straight since taking the 1 1/16-mile Three Ring at Calder in December 2007. She switches from turf to dirt and shortens from a route to a sprint in her second start for trainer Bruce Levine, who is 4 for 15 in that category with runners returning from a break of 31 to 60 days.\r\nThe best recent form in the field belongs to Unicorn Girl, a winner of back-to-back $32,000 to $35,000 claiming races at Monmouth but idle since July 18, and Cat&rsquo;s Got Legs, who won for a $32,000 tag at Monmouth last time out on Aug. 15.
