Fat Kat, a romping winner in three straight races on muddy or sloppy surfaces, will try to transfer her superb form to a dry track when she makes her stakes debut in Saturday’s $75,000 Jostle Stakes for 3-year-old fillies at Parx Racing. The 6 1/2-furlong race, which goes as race 10 at 5:20 p.m. Eastern, drew a field of six, including Miss Preakness runner-up Stormy Novel and Tea Time, a minor stakes winner in New York. After finishing far back in her career debut in February, the Pennsylvania-bred Fat Kat has reeled off three consecutive victories by wide margins, all going 5 1/2 furlongs. She will be running on a fast track and racing beyond six furlongs for the first time. Her most dangerous rival might be Stormy Novel, who has the tactical speed to stalk and pounce. A two-time winner at Parx early this year, Stormy Novel flashed high speed before fading when she tried a mile in the Grade 3 Bourbonette Oaks at Turfway Park and then rebounded to outrun her 24-1 odds when she rallied to finish a close second in the six-furlong Miss Preakness on May 16 at Pimlico. Tea Time won an overnight stakes in her last start as a 2-year-old last fall at Belmont but hasn’t done much in two starts this season. She was up close for the first half-mile of the Grade 2 Beaumont on Keeneland’s Polytrack and then lost all chance when she was pinched back and steadied at the start of the Miss Preakness. Tea Time is cross-entered in Saturday’s Crank It Up Stakes, a 5 1/2-furlong turf sprint at Monmouth Park. Spunderful, unbeaten in two starts, returns to sprinting after clearing her first allowance condition going 1 1/16 miles at Pimlico almost two months ago. Her trainer, Alan Goldberg, is 1 for his last 13 with last-out route winners returning to a sprint following a break of 31 to 60 days. Offlee Golden returns to the main track at Parx, where she won back-to-back starts early this year, following an unsuccessful experiment sprinting in a turf stakes in Maryland in April. Angel of Mercy looks for her third straight win after beating maidens in her fifth career start and clearing her first allowance condition by a neck at Delaware Park.
