Federer through to ATP semis

Roger Federer eased through to a 10th semi-final at the Barclays ATP World Tour Finals last night to leave David Ferrer and Juan Martin Del Potro scrapping for the second spot in Group B.

Federer took a 13-0 head-to-head record against Ferrer into yesterday's match at London's O2 Arena and did not really look in any danger of a first ever loss to the Spaniard as he came through 6-4 7-6 (7/5).
