Andy Murray will face US Open champion Juan Martin del Potro in the opening singles match at the Barclays ATP World Tour Finals.

The Scot, who took part in the draw at the London Eye yesterday, is in Group A with Del Potro, Roger Federer and Fernando Verdasco for the prestigious eight-man event at the O2 Arena.

Federer will play Verdasco on Sunday evening while Monday’s Group B action sees Rafael Nadal take on Robin Soderling in the afternoon before defending champion Novak Djokovic meets Nikolay Davydenko.

Murray, who reached the semi-finals on his first appearance at the end-of-season event last year, has won four out of his five matches against Del Potro, including their last meeting in the Montreal Masters final in August.(source)
