Roman Sloudnov has won the gold medal in the 100m breaststroke at the World Championships in Japan.
The Russian clocked 1 minute, 00.16 seconds, with Olympic gold medallist Domenico Fioravanti finishing second in 1:00.47 and American Ed Moses third in 1:00.61.
The 21-year-old Sloudnov had qualified fastest for the final by setting a world record of 59.94 in the semi-finals at the Marine Messe pool, slicing 0.03 off the world mark he set on June 29 in Moscow.
Moses, the Olympic silver medallist in Sydney last September, briefly held the world record with his 1:00.29 at the US trials on March 28.
Sloudnov is also due to swim in the 50m breaststroke and 400m medley relay.
