LONDON (AP) ? Roger Federer was on the decline ? or so the thinking went.
He was past 30. Had back problems. Tried experimenting with a larger racket. Was a family man, a father to two sets of twins now. Slid down the rankings. Reached zero Grand Slam finals over the past two years. Started losing before the quarterfinals at majors, including in 2013's second round at the All England Club, of all places, to a guy ranked 116th.
