MURRY BEATS DELPO

Andy Murray marked the start of London's five-year hosting of the ATP Tour Finals with a 6-3 3-6 6-2 win over U.S. Open champion Juan Martin del Potro in front of 17,500 fans inside the spectacular O2 Arena on Sunday.

The Briton withstood a ferocious comeback by the Argentine, who lost the opening five games, to open his account in Group A which also contains world number one Roger Federer and Fernando Verdasco who play later.
