LOUISVILLE, Ky. - On the eve of the start of a 30-day suspension stemming from a medication violation at Churchill Downs, Rick Dutrow sent out the winner of the Mrs. Revere Stakes at this same track. Mary's Follies surged to a 9-1 upset Saturday in the for the same team - Dutrow and jockey Kent Desormeaux - that won the 2008 Kentucky Derby here with Big Brown. Mary's Follies, owned by Paul Pompa Jr., returned $20.80 after drawing clear in midstretch to win by 1 1/2 lengths over Keertana in a field of 14 3-year-old fillies. Romacaca was third, with Hot Cha Cha, the 2-1 favorite, finishing fourth. The $209,500 Mrs. Revere was just the second race on turf for Mary's Follies, a More Than Ready filly whose lone other attempt had resulted in a victory in the Grade 3 Boiling Springs at Monmouth Park in June. Dutrow, who was not on site for the race, is banned from Sunday through Dec. 14 for a clenbuterol overage in a horse he ran here the day before Big Brown won the Derby. Mary's Follies had been "training unbelievable for the last month," Dutrow said from his apartment in New York. "It looks like she might be just a grass horse. She's a nice little filly. The jock gave her a great ride, and she had a great trip. All good there." Mary's Follies now has 4 wins and 3 seconds from nine overall starts. She finished 1 1/16 miles in 1:41.73 over a firm turf course. War Kill led early in the 19th Mrs. Revere, with Romacaca chasing closest. Turning for home, Keertana, a 13-1 shot under Jesus Castanon, loomed boldly on the outside, but Desormeaux challenged to her inside after maneuvering around the tiring leaders and proved clearly best. Hot Cha Cha, winner of the Grade 1 Queen Elizabeth II Challenge Cup at Keeneland in her last start, was amid traffic for much of the way before shaking loose with a mild late bid.
