Japanese teenager Akihiro Yamaguchi set a world record in the 200-metre breaststroke yesterday at a national swimming meet in Tokyo, nearly breaking the 2 minutes, 7 seconds barrier.

The 18-year-old Yamaguchi clocked 2:07.01 at the event in Gifu to shave 0.27 seconds off the mark set by Hungary’s Daniel Gyurta when he won gold at the London Olympics.

Yamaguchi was left off the Japanese Olympic team after finishing behind four-time gold medallist Kosuke Kitajima in the national trials.
