Del Potro has won the toss and chose to receive.
The players are walking out to the usual funky music at the 02 Arena. Not long to go now and in a couple of hours or so we’ll know the semi finals line-up
Play is due to start shortly and with Del Potro almost certainly needing victory to progress, we should be in for an absolute treat here. Send me your thoughts on the match on twitter @fmasefield.
Federer goes into today’s match as the strong favourite. He has a 13-3 winning record against Del Potro but Del Potro won their last meeting in the final of the Swiss indoors in Basel. He also won in their only other meeting in the ATP World Tour Finals in London in 2009, shortly after he beat Federer to claim the US Open title.
If Del Potro loses but wins one set he could still progress if Ferrer loses the evening match in straight sets. But if Ferrer also loses in three sets, he and Del Potro would be tied on wins and losses and sets for and against. It would then go down to games won to determine who progresses.
Should Federer win, he will face Andy Murray, who finished second in Group A behind Novak Djokovic. Del Potro could still possibly win the group if he beats Federer in straight sets and have a better winning sets ratio than Federer. If that happens, he will play Andy Murray in the semi final.
Federer has already qualified for the semi finals after beating David Ferrer on Thursday but Del Potro must beat Federer and hope that Janko Tipsarevic beats Ferrer in the evening match to progress.
