Candy Stables' homebred Queen's Plaza took the lead soon after the start and never looked back, romping to a 3 1/4-length victory in the $100,000 Sorority Stakes for 2-year-old fillies at Monmouth Park Saturday.Paragon Queen, part of the 1-10 entry owned by Bob and Beverly Lewis, broke down on the backstretch a little more than a furlong into the race. Jockey Eibar Coa escaped without injury, but Paragon Queen was euthanized.Only four started (with three betting interests) after the scratches of Ruby Be Mine and Dressed for SuccesThe longest shot on the board at 7-1, Queen's Plaza, trained by Tom Bush and ridden by Stewart Elliott, had no trouble holding off Dance Away Capote. Bold Outlook, the other half of the entry, trailed in third, 7 1/4 lengths farther back.The winner raced the six furlongs over a fast track in 1:11 3/5 and paid $16.20 to win. There was no place or show wagering. The exacta paid $46.60.Queen's Plaza, a dark bay filly by Forestry, broke her maiden in her last start at Belmont Park in July."We had confidence in her coming into this race," Bush said. "I'm really delighted to win this race for her owners, who bred her. It's nice to get some black-type in her. She's a small filly, she doesn't carry much flesh, so we'll give her some time before her next start. It was really a shame to see that other filly (Paragon Queen) go down. It really takes a lot away from it. It was just a terrible thing."Elliott said, "She made the lead pretty easily. She tried to drift a little, but she kept running well. She was pretty much push-button to ride."
