Kazan (Russia), Aug 5 Britain's World Championships debutant James Guy beat hot favourite Sun Yang of China to win the men's 200 metres freestyle swimming event here.
Guy, who trailed Sun in Sunday's 400m final to finish second, won 200m in one minute and 45.14 seconds on Tuesday. Sun was first by the 150m mark, but Guy made a strong sprint in the last 25m to win gold, reports Xinhua.
Sun took second spot in 1:45.20 while Paul Biedermann of Germany, world record holder of the event, was third in 1:45.38. American veteran Ryan Lochte came fourth in 1:45.83.
"I am happy with the time. 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. Guy surpassed me in the very last metres," said Sun, Olympic runner-up of the event.
Sun, who will compete in four individual events here, took sixth in the 800m freestyle heats earlier.
"I felt tired. I have been here since this morning. I did what my coach told me to do and I will try my best in the following competitions," Sun said.
The 800m freestyle final will be held on Wednesday.
