HALLANDALE BEACH, Fla. - The Mailet, who won the Grade 3 Miesque at Hollywood Park in her 2-year-old finale, broke down a quarter-mile into a five-furlong workout here at Gulfstream Park on Friday and was euthanized later in the morning.\nThe Mailet, a daughter of Rock Hard Ten, finished far back on dirt in her first two starts but became an instant success once trainer Bruce Levine put her on grass for the first time last fall at Belmont Park. The Mailet rallied to win her maiden by 1 1/2 lengths in her turf debut before shipping west to upset the Miesque by a half-length on Nov. 29.\nLevine, who trains The Mailet for J.W. Singer LLC, was pointing his filly for the $125,000 Coconut Grove on Feb. 14.\n"It's hard to believe she did so much damage as easy as she pulled up," a somber Levine said shortly after accompanying his top 3-year-old Buddy's Saint back from the track following a routine gallop near the end of training hours on Friday. "Just having her as a broodmare would have been fine if we could have saved her, but she shattered her sesamoid and cracked her cannonbone. It's really heartbreaking.\n"This was a really nice filly, but when you have to make that phone call to the owners it doesn't make a difference even if it was a ten thousand claimer. It's the hardest thing in the world to do."\nBuddy's Saint is pointing for the Grade 1 Fountain of Youth Feb. 20. He was scheduled to work on Saturday.\n"Something like this makes you wary, but you've got to move on," said Levine. "The track has been much too hard the past several days, but I'm on a schedule with him and you just can't wait for the track to be exactly the way you want."
