U.S. stars Justin Gatlin, Allyson Felix, Dwight Phillips and Dee Dee Trotter all won their events Monday at the Super Track & Field Meet in Yokohama, Japan.

Although he didn't meet his pre-race goal of a sub 10-second clocking, 2004 Olympic gold medalist Justin Gatlin won the men's 100 meters in 10.04 seconds after taking the lead half-way into the race. Olusoji Fasuba of Nigeria was the runner-up in 10.13.

"I am really pleased with the season this year," said Gatlin. "I feel I have established better credit to my name and feel I am more consistent. My hamstring was a little bit tight about 20 meters to the finishing line, but it was a good race, I think my performance was good, the competition was great."

In the women's 100 meters, regining U.S. champion Lisa Barber led until the middle of the race before world 200m gold medalist Allyson Felix started to work her way back.

In the men's 400m hurdles, Masahira Yoshikata and World University Games champion Kenji Narisako led at the eighth hurdle, but they were unable to hold off 2005 world champion Bershawn Jackson, who grabbed the lead at the ninth hurdle before winning in 48.24 seconds. Narisako was the runner-up in 48.40.

Although 2004 Olympic gold medalist and reigning world outdoor champion Dwight Phillips was not in peak form in the men's long jump, his best leap of 8.06 meters/26 feet, 5 inches easily won the competition. Japan's Daisuke Arakawa was the distant runner-up with a best of 7.61m/24-11.75.

The fifth-place finisher in the women's 400 meters at the 2005 World Outdoor Championships in Helsinki, Dee Dee Trotter faced a strong challenge, but held on to win the women's 400m at Yokohama. Trotter won the race in 50.03 seconds in holding off runner-up Christine Amertil of the Bahamas, who finished in 50.09.
