Guy, who trailed Sun on Sunday' s 400m final to finish second, won 200m in one minute 45.14 seconds. Sun was first by the 150m mark but Guy made a strong sprint in the last 25 meters to win the gold.

"I am happy with the time," said Sun, Olympic runner-up of the event. "It is my first 200m medal in the world championships."


"It' s a final with a very high level and I have never met so many strong rivals in the world championships," Sun added. "Guy surpassed me in the very last meters."


Sun, who competes four individual events at the worlds, took a sixth finish in the 800m free heats earlier Tuesday.


"I felt tired. I have been here since this morning," Sun said. "I did what my coach told me to do and I will try my best in the following competitions."
