|Andy Murray withdraws from the ATP Tour Finals|
Andy Murray has pulled out of the ATP Tour Finals with a groin injury. It is not entirely surprising after having treatment during his defeat against David Ferrer yesterday. Whilst warming up with his replacement, Janko Tipsarevic on Sunday, he was also touching his arm which could also have been a factor to him pulling out of the last tournament of the year. As Federer has beaten Nadal, Federer regains the No.3 ranking.
