TOKYO, July 30 ― Tatjana Schoenmaker won the women's 200m breaststroke today in a world record time of 2:18.95 to deliver South Africa's first gold medal of the Tokyo Games while Emma McKeon won the 100m freestyle for Australia's sixth gold in the pool.

Russian Evgeny Rylov won the men's 200m backstroke for his second gold of the week.

Schoenmaker, who had already claimed silver in the 100m breaststroke on Tuesday, powered to the finish 0.97 seconds ahead of American Lilly King, with Annie Lazor of the United States in third.

The 24-year-old's victory marked the second African gold medal in the pool following Tunisian Ahmed Hafnaoui's success in the men's 400m freestyle on Sunday.

King led until the 150m turn when Schoenmaker went in front and then delivered a powerful final length to smash the world record and grab gold.

McKeon led at the turn in the 100m free and held off Hong Kong's Siobhan Haughey down the final straight to win by 0.31 seconds, with team mate Cate Campbell taking bronze.

World champion Rylov won the 200m backstroke in an Olympic record 1:53.27, with Rio gold medal winner Ryan Murphy taking silver.

Rylov, who had already won the 100m backstroke gold, led from the outset and never looked in danger, winning by a comfortable margin of 0.88 seconds. ― Reuters
