Dimitrov rises to third after London triumph
Bulgaria's Grigor Dimitrov climbed to a career-high world ranking of third after landing his biggest title to date at the ATP Finals in London. Dimitrov, 26, defeated David Goffin 7-5, 4-6, 6-3 in Sunday's final at the O2 Arena to move up three places -- behind only Rafael Nadal and Roger Federer -- after a breakthrough year featuring four titles. Alexander Zverev dropped one spot to fourth after failing to advance past the round-robin stage in London, while Jack Sock, beaten by Dimitrov in the semi-finals, rose one place to eighth. Goffin, who will spearhead Belgium's bid for a first Davis Cup title this weekend against France in Lille, clawed himself up to seventh after his run to the final.
