Intro:

Usain Bolt labours to victory in the 200m at the New York Diamond League meeting, while Tyson Gay wins the 100m and Briton Tiffany Porter finishes second in the women's 100m hurdles.

Script:

Usain Bolt clocked 20.29 seconds to win the 200m at the New York Diamond League meeting.

The 100m and 200m world record holder edged out 19-year-old training partner Zharnel Hughes of Anguilla and fellow Jamaican Julian Forte.

Bolt ran a conservative bend but was too powerful for his rivals in the home straight.

David Rudisha prevailed in the 800m, recording a time of 1:43.58 seconds. It marked a winning return for the Kenyan, who pulled a leg muscle in Ostrava which kept him out of the Birmingham Diamond League.

In the men's 100m, American Tyson Gay pipped Keston Bledman in a time of 10.12 seconds with Nesta Carter third.

Britain's Tiffany Porter came second in the 100m hurdles in a time of 12.81 seconds, 0.16 seconds behind American Sharika Nelvis.
