Japan's national champion Ryo Tateishi brought home a gold in the men's 100-meter breaststroke at the Guangzhou Asian Games here on Monday. Ryo made a strong dash in the 50m mark to take the lead and clocked one minute and 0.38 second to lift Japan's first swimming title in two days. Yevgenly Ryzhkov of Kazakhstan took the silver in 1:01.13, while Chinese Wang Shuai beat four-time Olympic champion Kosuke Kitajima of Japan to take the bronze in 1:01.71. Kitajima only managed a fourth finish by clocking 1:01.85. 'I only took a silver in yesterday's 50m breaststroke, and I was unsatified with it,' said 21-year-old Ryo. 'The gold medal was very important to the Japanese team. I hope it can be a good start for us.' 'I feel sorry for Kitajima,' he added. 'He trained really hard. Maybe he was not in good shape tonight. He is a very great swimmer.' 'I didn't swim well in the heat,' said bronze medallist Wang. 'But I performed well in the final. I am excited to compete with Kitajima. I think it is possible to beat him in the 200m breaststroke tomorrow.' Kitajima, 28, who was hailed as 'Frog King' in China for his Beijing triumphs and has set his sights on a third straight breaststroke double at the 2012 London Olympics, said after the race:'I didn't swim well tonight. I will do my best in the 200m breaststroke tomorrow. '
