Murray to face Federer in semis

Andy Murray will meet Roger Federer in the semi-finals of the ATP World Tour Finals on Sunday after David Ferrer bowed out with a win.

Ferrer and opponent Janko Tipsarevic were in the unusual situation of both being unable to reach the semi-finals but knowing their result would have an impact on those who had.

In the end, Ferrer's 4-6 6-3 6-1 victory meant he joined Federer and Juan Martin Del Potro on two wins in Group B but his record was the worst in terms of sets won and lost, with Federer top by that criteria.

Del Potro, who beat Federer earlier to book his place in the last four, will meet Group A winner Novak Djokovic in the other last-four clash.

Ferrer was particularly unfortunate after beating Del Potro in the first round of matches, while Tipsarevic had won only eight games in total against the Argentinian and Federer.

The Serb began the tournament struggling with illness and has been well below his best but he came out firing tonight.

With 200 ranking points and US dollars 130,000 up for grabs, there was still plenty to play for, but Ferrer, usually the most dogged of competitors, looked out of sorts at the start.

He lost the first four games and, although he staged a good fightback, it was not enough to deny Tipsarevic his first set of the tournament.

Among the almost full crowd was Arsenal midfielder Jack Wilshere, and Ferrer cheered the Spanish fans by winning the first three games of the second set.

This time it was Tipsarevic's turn to come back, but he could not sustain it, and he smacked his racquet angrily to the ground as he was broken in the third game of the decider, after which he did not win another game.
