Pakistan, Sept. 26 -- Japanese teenager Shin Ohashi moved closer to a hat-trick of Asian Games breaststroke golds after qualifying for the 50m final on Friday, the morning after smashing the 200m world record.

The 17-year-old clocked an astonishing 2min 04.83sec in Tokyo to slice more than half a second off the previous 200m breaststroke mark held by China's Qin Haiyang.

It was Ohashi's second gold of the Games, having won the 100m breaststroke gold after a dead heat with China's Dong Zhihao.

The world record continued Ohashi's stunning rise in the sport and marked him out as the man to beat at the 2028 Los Angeles Olympics, where he could face French superstar Leon Marchand.
