ARLINGTON HEIGHTS, Ill. - It's an old racetrack cliche about slow races: "You could've timed that one with a sun dial." And it perfectly fit the Possibly Perfect Stakes on Saturday at Arlington.\nRained from turf onto Polytrack, the Possibly Perfect looked on paper like it had a pace void. Looked that way out on the track, too. Cherokee Queen is no speed horse, but she easily made the lead, set what seemed like impossibly slow fractions, and turning for home sprinted away from the closers in the field to win the $53,000 Possibly Perfect Stakes by 5 1/2 lengths.\n"She got to the front and rated herself," said winning rider Jesse Campbell. "She didn't pull at all."\nCherokee Queen was 3-5 when she finished a tough-trip second in a second-level allowance race here May 23, but this time, things went her way. The first quarter-mile went up on the board in 26.57 seconds, the half in 52.81. Cherokee Queen was going easy, and just as stalking Russian Rosie came up to Cherokee Queen before the top of the homestretch, Campbell said "go."\n"When I got to the quarter pole, I let her zip," Campbell said. "I wanted to let her go and open up."\nOpen up she did, and no one got close to Cherokee Queen, who finished up in 1:53.71 for 1 1/8 miles on Polytrack, and paid $13.40 to win for trainer Graham Motion and owner J. Mack Robinson. \nGuanahani, at 21-1 the longest price in a six-horse field, came up the fence to get second by a nose over favored You Go West Girl. Russian Rosie was fourth, followed by Communique and Lady Carlock.
