South Korea's swimming wunderkind Park Tae Hwan said Thursday he would keep low key despite seizing three gold medals and beating two Asian records in the Asian Games.

"I won many gold medals at this competition not because I was more excelled than the others, but because the Chinese and Japanese were not in good form," said the high school student from Seoul.

"I'm not going to be arrogant about swimming gold medals. I will not be complacent about being the fastest swimmer in Asia. I will continue to work hard to win more medals," he said.

The 17-year-old grabbed his third gold on Thursday in 1,500m freestyle, beating his Chinese opponent Zhang Lin not only for gold but for a new Asian record.

Park clocked 14 minutes 55.03 seconds to improve the previous mark of 15:00.27 set by Zhang, 19.

"Zhang is a strong rival for me. Perhaps he will be for a very long time to come," said Park. "It was a close match for us. I think I only did better than him in a few little details like turning techniques."

Park claimed the 200 free title in a new Asian record of 1:47. 12 on Sunday and took the 400 free gold in 3:48.44 two days later. He also had a silver from 100 free and three bronzes from relay events including 4x100 and x200 free as well as 4x100 individual medley.

"I've never competed in so many races like this. In general, it 's a good experience for me," he said.
