The Czech tennis player Tomas Berdych remains in the hunt for a place in the semi-finals of the ATP World Tour Finals after he battled back to beat Serbia's Janko Tipsarevic in three sets in London.
Berdych, who lost his opening game against Novak Djokovic, looked on the way out when Tipsarevic, playing in place of the injured Andy Murray, held a match point in the final set tie-break, but the seventh seed recovered to seal a crucial Group A victory.
Now Berdych has to beat David Ferrer in his last match and hope other results go his way to reach the semis, while Tipsarevic's participation is likely to end with his final fixture against Djokovic.
