ETOBICOKE, Ontario &ndash; Maidens are prevalent in Saturday&rsquo;s $250,000 Princess Elizabeth Stakes, and Lisvernane has as good a chance as any in the 1 1/16-mile route for Canadian-bred 2-year-old fillies.\r\nLisvernane is trained by Carolyn Costigan, who won last year&rsquo;s Princess Elizabeth with Roan Inish, a gifted maiden from Ireland. Roan Inish evolved into one of Woodbine&rsquo;s leading 3-year-old fillies this year, during which she won the Woodbine Oaks and ran third in the Queen&rsquo;s Plate.\r\nLisvernane was a non-threatening fourth in each of her first two outings, in the Shady Well Stakes and a seven-furlong maiden special on the grass. She went a mile and 70 yards last time in a maiden special event on the Polytrack and took the long way around en route to ending up third behind Wyomia, who subsequently won the Grade 3 Mazarine Stakes and is Breeders&rsquo; Cup bound.\r\nLisvernane, a daughter of Arch, has matured throughout the year, according to Costigan.\r\n&ldquo;She&rsquo;s learned every step of the way and has come a long way mentally,&rdquo; Costigan said. &ldquo;She&rsquo;s always been excited to train and enjoys her day job very well, so she&rsquo;s a pleasure to train. She&rsquo;s very much an Arch &ndash; quite an ugly duckling as a yearling, and is turning into a nice big, leggy, long-striding filly.&rdquo;\r\nCostigan said Lisvernane has trained forwardly leading up to the Princess Elizabeth, which will be her first race with blinkers.\r\n&ldquo;She&rsquo;s fit and ready, and she worked very nicely on Monday,&rdquo; Costigan said. &ldquo;She&rsquo;s set up nicely for this race.&rdquo;\r\nBubbles to the Top should be well-backed in her first venture around two turns. After ending up second in her debut, she finished fourth in the Nandi Stakes, third in the Muskoka Stakes, and then second in the Victorian Queen Stakes.\r\nTrainer Mike DePaulo is confident that Bubbles to the Top will handle a route of ground.\r\n&ldquo;She&rsquo;s from a family that ran long,&rdquo; DePaulo explained. &ldquo;She&rsquo;s got a pretty good mind and isn&rsquo;t speed-crazy. She&rsquo;s pretty rateable.&rdquo;\r\nCharismatically outran Lisvernane for second in the aforementioned maiden route Sept. 19 and has since been fifth in a seven-furlong maiden sprint on the grass.\r\nLucky Be Me is the lone stakes winner in the lineup. She captured the seven-furlong Muskoka in a gutsy performance Sept. 6 but was a well-beaten fifth most recently in another restricted stakes, the six-furlong Victorian Queen.
