Slider, ridden by red-hot Rene Douglas, challenged at the top of the stretch but was no match for the winner. He finished second, one length ahead of Discreet Hero. Hero's Tribute, Mercenary, favored B inthebest and X Country completed the order of finish."He was happy all the way around," said Melancon, who was in from Louisiana to ride Bonapaw. "I knew if I could keep him happy and relaxed, they weren't going to beat him. I thought I was in the best spot the whole way.""I thought he would win when he turned for home," said Rene Douglas, of SLider. "I went inside perfect. It looked like he was going to win. He hesitated a little bit at the end."The win was the 15th in 32 career starts for Bonapaw, who raced in Dubai in March, then was rested until the July 4 Iowa Sprint Handicap at Prairie Meadows, where he finished fourth.Though Douglas was denied in the stakes race, the meet's leading rider extended his lead atop the standings by winning the first five races on the card.
