FUCHU -- A mere three weeks after a 5-length win of the NHK Mile Cup, King Kamehameha once again reigned supreme, this time with a length-and-a-half record win of the year's biggest racing event, the Nippon Derby.

Before some 122,000 fans on a sweltering, sweaty Sunday at Tokyo Racecourse, King Kamehameha extended his winning streak to four with a rout of 18 of Japan's top racehorses and a winning time (2:23.3) that whittled 2 seconds from the race record.

"I still can't really believe it," jockey Katsumi Ando said of the win. "But I'm more relieved that overjoyed. I really believed in him and I wanted him to win so he could show just how strong he is," Ando said of his mount.
