Djokovic defeats Del Potro to reach ATP final in London

Novak Djokovic fought back from a set down to defeat Juan Martin del Potro and reach the final of the season-ending ATP Tour Finals event in London.

The Serbian closed out a 4-6 6-3 6-2 victory by winning 11 of the last 14 games, with a forlorn Del Potro looking well beaten by the end of the match after having dominated the opening stages.

World number one Djokovic lined up a meeting with either Roger Federer or Andy Murray in the final.
