The third Round Robin day at the 2009 Barclays ATP World Tour Finals brings a much awaited clash between current world number one Roger Federer, and Britain's hope and local favourite Andy Murray along with the first time match-up between U.S. Open champion Juan Martin Del Potro and Spaniard Fernando Verdasco. Both matches promise to be interesting in their own aspects, however, the results will decide the fate of the two players who will take a step towards claiming the biggest prize on the ATP World Tour.

Federer won 6-2, 7-6(8)

Roger Federer has been beaten by Andy Murray twice this year including a three sets loss in Indian Wells, but the pair's last meeting was dominated by the Swiss, who had, by then, claimed two Grand Slams including his record breaking Wimbledon win. The truth is that Federer's biggest asset is his confidence which is more than enough to topple the biggest champions in the circuit. This is one factor which will be a driving force in today's encounter against Murray, who will have the entire crowd behind him. Despite the home-fans support, the result seems to be going in Federer's favour.

First meeting

This battle between the first timers is perhaps the most crucial Round Robin match of the Group A as both Verdasco and Del Potro have lost their opening day encounters and another loss will probably set the tone for the semifinal line up. Both Del Potro and Verdasco impressed on Sunday with their resistance, however, it was Del Potro, who looked closer to a turn around in the match against Murray and this is probably the Argentine's strongest aspect, the ability to turn things around, the best of which we saw in the u.S. open final. Both players are loaded with the tour's best groundstrokes ( forehand in particular ) and today's match will be a showcase of exhilarating shotmaking at all corners of the court. Despite the similar style of play, Del Potro seems to have an edge in the match-up.
