YOKOHAMA -- World record-holder Asafa Powell was disqualified before the 100 meters at the Seiko Super Meet on Sunday and Japan's Shingo Suetsugu seized his opportunity to race to victory.

Suetsugu won in 10.12 seconds as Powell missed out on bettering his world mark of 9.77 seconds after committing the second false start at Nissan Stadium.

Naoki Tsukahara of Japan edged Australia's Patrick Johnson for second with both clocking 10.26 seconds, but the race was overshadowed by Powell's shock exit.
