Britain's Stephen Parry finished sixth in the Olympic 200metres butterfly final on Tuesday as American Tom Malcohow won in a new Games record.

The 23-year-old, competing in his first Games, came home in one minute 57.01 seconds - around 0.7 seconds down on his own Commonwealth record.

World champion Malchow clocked his third Games record in successive rounds to win in 1:55.35.

Parry, swimming in lane one, was fifth mid-way through the race but dropped back one place on the third leg.

Ukraine's Denys Sylant'yev took the silver medal in 1:55.76 with Australia's Justin Norris third in 1:56.17.

Liverpool's Parry said: "I'm obviously disappointed. I went into the event ranked fourth in the world and I wanted to improve on that.

"But I should be pleased. I thought I was well placed after 150m, but then it did not quite happen for me.

"I've known those other guys for quite a few years now and I was having fun out there. I know I can do better, but now it is time to consolidate and re-evaluate."

Birmingham's Georgina Lee broke her personal best in the 200m butterfly for the second time today.

The 19-year-old, in her first Olympics, carved a massive 0.76secs off the mark to reduce it to 2:10.33 when finishing fifth in the semi-final.

Lee, only the second British swimmer to achieve a new career best in the Games so far, finished fifth just ahead of national record holder Margaretha Pedder who was sixth in 2:10.49. Both missed out on the final.
