Stamina ruled in Friday evening's , as Hightap benefited from a torrid pace and a patient Shaun Bridgmohan ride to beat fellow closer Sweet Relish by three-quarters of a length. \nLocally based hope Don'ttalktome made the early lead and was pressured by 22-1 longshot Mein Fraulein through demanding fractions of 23.83 and 46.53 seconds in the 1 1/16-mile race. When Don'ttalktome began to toil on the far turn, Mein Fraulein briefly put her nose in front. Poised to strike, Hooh Why, winner of Keeneland's Grade 1 Ashland Stakes and the 8-5 favorite, assumed command at the three-sixteenths marker, but her rally quickly petered out.\nHightap, an attractive grey daughter of Tapit trained by Steve Asmussen, finished strongest to hold off the determined efforts of the Donnie K. Von Hemel-trained Sweet Relish, who swung five wide for the stretch run, and the other Von Hemel trainee, Peach Brew, who split tiring rivals to make her eventual third-place bid, just a neck behind Sweet Relish. Outstaying the field of six 3-year-old fillies, Hightap registered a time of 1:44.00.\nOwned by Winchell Thoroughbreds LLC and Gainesway Thoroughbreds Ltd., Hightap collected $120,000 in winning her second straight Grade 3 stakes. In her previous start on May 30, she won the Dogwood Stakes at Churchill Downs. Sent off as second choice in the Iowa Oaks, she returned $6.20.\nSaylorville: Lady Chace hangs on by a head\nThe Saylorville Stakes, a $100,000 sprint for filllies and mares, kicked off opening night of the Iowa Festival of Racing. Racing in an evenly matched field of eight, the strapping Lady Chace, ridden by Prairie Meadows's leading rider Terry Thompson for Kentucky-based trainer Steve Margolis, fended off the game effort of 14-1 longshot Nadeshiko to score by a diminishing head.\nWith Oklahoma invader Miranda Diane blazing a trail of 21.32 and 43.89 in the six-furlong event, Thompson tucked Lady Chace neatly in a striking position. Taking advantage of plenty of space toward the rail, Lady Chace surged to a clear lead turning for home and found enough under pressure to hold off the Greg Foley-trained Nadeshiko, who ducked out three wide at the sixteenth marker when rallying. The Asmussen-trained P.S.U. Grad hugged the rail throughout and managed a third-place finish, one length behind the willing Nadeshiko. \nEarning $60,000 for owners Michael Shustek and Don W. Stanley, Lady Chace, a 4-year-old daughter of champion Tiznow, scored her first stakes win. Stopping the clock in 1:08.92, Lady Chace, the second choice in the wagering behind the Tom Proctor-trained Sly Storm, who finished seventh, paid $8.80 to win.
