Justin Gatlin geared up his bid to unseat sprint king Usain Bolt at this summer¡¯s Rio Olympics with a time of 10.02 seconds to win the 100 meters at the Golden Grand Prix on Sunday.

American Gatlin, who lost out to Jamaica¡¯s Bolt in both the 100 and 200 meters at last August¡¯s world championships in Beijing, eased home ahead of Japan¡¯s Ryota Yamagata and Ramon Gittens of Barbados at Kawasaki¡¯s Todoroki Stadium.

¡°The race felt good,¡± said Athens Olympic 100-meter champion Gatlin. ¡°I knew I was going to have a head wind when I practiced yesterday. Today I talked to my coach on the phone and he told me to have a good start. He knows that Japanese athletes have good starts, so just stay with them.
