Andy Murray to face Juan Martin del Potro in Davis Cup opener

Andy Murray has been drawn to face Juan Martin del Potro in the opening rubber of the Davis Cup semi-final between Great Britain and Argentina.

The world number two has returned to Leon Smith's squad after sitting out the quarter-final triumph over Serbia and he will hope to get the team off to the perfect start against in-form Del Potro, who has been excellent over the past six weeks.

Last month, the pair contested the Olympic final, with Murray prevailing in four sets to win his second gold medal at the Games.

In the second rubber, Kyle Edmund - who recently reached the fourth round of the US Open - will play Guido Pella.

In their one previous meeting at the Indian Wells Masters earlier this year, Pella launched a late fightback to get the better of Edmund by a 6-7 6-4 7-5 scoreline.
