Federer loses, to face Andy Murray in semis

Towering Argentine Juan Martin del Potro ended Roger Federer’s three-year unbeaten run at the ATP World Tour Finals on Saturday to clinch a semifinal against world number one Novak Djokovic at the season-ending showpiece.

Del Potro, fresh from beating the Swiss in the Basel final a fortnight ago, claimed a 7-6 4-6 6-3 victory at the O2 Arena to guarantee himself runner-up spot in Group B with a 2-1 record, the same as defending champion Federer who will meet Andy Murray for third time in London this year.
