Fed express keeps delivering wins

For a player described as a spent force a year ago, Roger Federer is proving he still has what it takes to win.

After a disappointing 2013 campaign that he finished with a modest 45-17 record, the 17-time Grand Slam champion enjoyed a superb resurgence this season, losing to top-ranked Novak Djokovic in an epic Wimbledon final and adding five new titles to his collection.

On Tuesday, Federer posted his 70th win on the Tour this year - the most by any player - with a clinical 6-3, 6-2 victory over Japanese newcomer Kei Nishikori at the ATP Finals.
