Gabby Logan introduces highlights of the seventh Diamond League meeting of the year from New York's Icahn Stadium, with Usain Bolt and David Rudisha headlining a world-class field.

Six-time Olympic champion Bolt returns to the city for the first time since 2008, when he first broke the 100m world record by running 9.72 seconds - a time he has subsequently lowered to 9.58 seconds.

Rudisha, the reigning 800m Olympic champion and world record-holder, will be looking for his fourth consecutive victory in New York. Twenty-year-old rising star Ajee Wilson is considered one of the best-ever athletes to come out of the New Jersey high school system. The American is guaranteed a warm welcome by his hometown crowd.
