ELMONT, N.Y. - Tom Albertrani saddled six stakes winners during the recently concluded meet at Gulfstream Park and broke fast at Belmont by sending out Flashing to outduel 6-5 favorite Saarlight in Saturday's Grade 3, $196,000 Nassau County Stakes for 3-year-old fillies.\nFlashing ($6) broke alertly from the rail to take the lead and was pressed by Saarlight through an opening quarter in 22.14 seconds. Saarlight wrested command midway on the turn after a half-mile in 44.63 and opened daylight through midstretch after six furlongs in 1:09.73 over a sealed muddy track. She drifted out while tiring, and Flashing, who had been switched to the outside, was along late to win by 1 1/4 lengths in 1:23.59 for seven furlongs.\nIt was another 6 1/4 lengths back to third finisher Haley's Lolipop, who had a neck on Maryville. Frolic's Dream completed the order of finish.\n"I think she was a little intimidated being on the inside early on," said winning rider Javier Castellano. "At the quarter pole, when it looked like the other horse was going to try and open up, I took my time and put her outside."\nFlashing won for the fourth time in five starts and earned $120,000 for her first graded stakes win.\n"I was only concerned about the distance - she'll be a much better filly going over a mile," Albertrani said. "This was a last-minute decision, and we decided to take advantage of the short field. We're thinking about the Acorn [on June 6] and the Coaching Club American Oaks [on July 25], but we'll see how she comes out of it and make those decisions later."\nThe Beaugay and Fort Marcy, a pair of 1 1/16-mile grass stakes formerly run at Aqueduct, completed Saturday's Grade 3 stakes tripleheader.\nOver an inner course labeled good, My Princess Jess ($6.90) returned for her first start as a 4-year-old while meeting older fillies and mares for the first time, and unleashed a strong late run to win the $109,000 Beaugay by 1 3/4 lengths under Cornelio Velasquez.\nMaking her first start since November, My Princess Jess settled in midpack off a deliberate pace, rallied outside turning for home, and surged past Sunshine for Life and Carribean Sunset to win going away.\nMy Princess Jess, a three-time stakes winner last year for Barclay Tagg, ran the 1 1/16 miles in 1:44.83, and earned $65,400 for Lael Stable.\n"Cornelio rode her perfectly," Tagg said. "I told him to tuck her in and wait until she got past the quarter pole. She really explodes if you wait until she gets past the quarter pole."\nCarribean Sunset finished well to edge Social Queen by a neck for second as the slight 2-1 favorite. Sunshine for Life faded to fourth.\nIn the $106,500 Fort Marcy, run over a good Widener course, Cosmonaut ($6.20) pressed 7-5 favorite Tam Lin from the start and overpowered her in midstretch to win by 1 1/2 lengths in 1:42.60 under Jose Lezcano.\nCosmonaut was making his first start since a second-place finish at 1-2 in the Arlington Handicap last July. The 7-year-old earned $63,900 for Flying Zee Stable and increased his career bankroll to $1,357,313.\n"When I saw the fast fractions, I was a little concerned," said winning trainer Phil Serpe. "The turf is a little soft, and they were going pretty fast for soft turf, but he showed how great he really is today. He's an unbelievable little horse."\nTam Lin, winner of the Kelso Handicap here last fall, saved the place narrowly over Operation Red Dawn. Interpatation was fourth. Silver Tree, last year's Fort Marcy winner, finished fifth.
