LONDON - Roger Federer advanced to the semifinals at the ATP finals with a match to spare.

The six-time champion earned his second straight victory at the season-ending tournament, this time beating David Ferrer 6-4, 7-6 (5) Thursday.

But it wasn't so easy for the 17-time Grand Slam champion, who improved his record to 14-0 against Ferrer. Two days after controlling his opening match against Janko Tipsarevic with a dominating serve, Federer faced 10 break points on Thursday, and saved nine of them.

In the late Group B match, Tipsarevic will face Juan Martin del Potro.
