Roger Federer is in an unfamiliar position as the tennis season winds down still fighting to secure a spot in the eight-man field at the ATP World Tour Finals in London.
Over the last decade, Federer usually had his spot in the season-ending tournament wrapped up months in advance. Now he's in the seventh spot coming into this week's Shanghai Masters, needing to put distance between himself and his nearest rivals, Stanislas Wawrinka and Richard Gasquet.
Federer hasn't missed the tournament since his first appearance in 2002, winning it six times.
"It's part of my goals for the end of the season, it's definitely a driving force behind me playing Shanghai, Basel and Paris now,'' Federer said. "I'm not just playing the tournaments trying to win it, but I'm also playing trying to qualify for the World Tour Finals. It kind of goes hand-in-hand.''
Shanghai is Federer's first tournament since his fourth-round loss at the U.S. Open, which came on the heels of a second-round exit at Wimbledon. In what has been a disappointing year for the 17-time Grand Slam champion, questions about his form have become common place at news conferences. He bristled a bit Monday when asked about the possibility of missing the ATP finals, and how much that was weighing on his mind.
