Unlike her six opponents in Saturday’s $75,000 Maryland Racing Media Stakes at Laurel Park, the 4-year-old filly Kit Kats Luck has proven she can handle 1 1/8 miles. What’s less clear, however, is whether she’s fit enough to go nine furlongs after turning in the worst performance of her 13-race career. Kit Kats Luck, a seven-length wire-to-wire winner when she raced 1 1/8 miles last October, didn’t show a drop of her customary early speed five weeks ago when she finished last of eight, beaten 14 1/4 lengths, in an overnight stakes at Parx Racing. Whether she will rebound upon returning to Laurel, where she is 4 for 7 lifetime, is the key question for handicappers searching for a winner in a field that is otherwise unproven or unsuccessful at Saturday’s distance. Until her flop last month, Kit Kats Luck had won four in a row, including her romp in a first-level allowance that was taken off the turf on Oct. 6. That day, she go away with extremely slow fractions of 49.91 seconds and 1:14.36. Her winning Beyer Speed Figure came back a modest 68, a number that is probably way too low to win against the competition she faces in the Maryland Racing Media. Among her rivals, Potosina, Blessed Soul, and Princess Nyla all come into Saturday’s race off a daylight victory. Princess Nyla may be the most intriguing challenger among that trio. A year ago, Princess Nyla finished a distant fourth in the Maryland Racing Media, her first attempt at nine furlongs, but was hung wide throughout the two-turn route and may be capable of better with a cleaner trip. She has won her two most recent starts, both going 1 1/16 miles. Potosina will attempt to prove her 11-1 upset in a five-horse field in the Jan. 22 one-mile Nellie Morse was no fluke. She has yet to prove effective going longer than a mile. Blessed Soul, claimed for $25,000 in September, steps up to stakes company after posting a four-length score and earning a career-best 84 Beyer on Jan. 21. In her previous two starts, she was narrowly beaten by Princess Nyla and finished 3 3/4 lengths in back of Kit Kats Luck. Music Please, unbeaten in three starts while racing exclusively at seven furlongs, makes the second start of her form cycle after finishing second to Potosina in the Nellie Morse.
