Yuki Koike clocked 9.98 seconds in the men's 100-meter race at the Muller Anniversary Games on Saturday to become the third Japanese sprinter to break the 10-second barrier.

Koike shaved 0.6 seconds off his personal best to place fourth at the 10th event of the IAAF Diamond League season, won by South Africa's Akani Simbine with a time of 9.93. Former Japan record holder Yoshihide Kiryu, the first Japanese sprinter to run the 100 under 10 seconds, finished seventh with 10.13.

"It was nearly a perfect run under the circumstances," said Koike, who matched Kiryu's 2017 record time with the help of a 0.5-meter tailwind.
