Japan¡¯s gold medal hope Daiya Seto failed to qualify for the men¡¯s 400-meter medley final after finishing ninth in the heats.

The 27-year-old Seto, the world champion and top ranked in the event, was the bronze medalist in Rio five years ago and favourite to win gold in Sunday¡¯s final before his shock exit.

Australia¡¯s Brendon Smith was fastest with a time of 4:09.27 followed by New Zealand¡¯s Lewis Clareburt and American Chase Kalisz.
