KEMPTON, England: Kauto Star was denied a record fifth King George VI Chase victory Saturday, finishing third behind Long Run and Riverside Theatre. Fifteen-time champion jockey Tony McCoy was almost unseated as 4-7 favorite Kauto Star stumbled at the penultimate fence. The 11-year-old defending champion had been attempting to surpass the record of four race victories he held jointly with Desert Orchid. The race was held three weeks after it was due to take place due to Kempton Park's frozen track. Long Run had jockey Sam Waley-Cohen on board and finished ahead of Riverside Theatre.
