Federer Seals Spot in ATP Tour Finals
LONDON — Evergreen Roger Federer has booked his place in the ATP World Tour Finals, joining world number one Novak Djokovic and Andy Murray as definites for the season-ending event in London.
The Swiss guaranteed himself a 14th successive appearance at the ATP's flagship tournament when he swept past American John Isner into the U.S. Open quarter-finals on Monday.
The 34-year-old, playing some of the best tennis of his illustrious career, is a huge favorite in London, having won two of his record six Tour Finals titles at the O2 Arena in 2010 and 2011. He reached the final there last year but pulled out with a back injury shortly before a showdown with Djokovic.
