Novak Djokovic fought back from a set down to defeat U.S. Open champion Andy Murray at the ATP World World Tour Finals in a re-match of their U.S. Open championship match.
The world No. 1 from Serbia defeated the third-ranked Murray from Britain, 4-6, 6-3, 7-5 in a group match at the season-ending tournament at London’s O2 arena.
It was the seventh meeting this season between the two men, who first played each other as juniors when they were 13 years old.
Djokovic, who now leads Murray 10-7, will move to the semifinals should France’s Jo-Wilfried Tsonga defeat former Wimbledon finalist Tomas Berdych of the Czech Republic later in the day in the other group match.
The ATP World Tour Finals feature a round-robin format. The world’s best eight singles players and doubles pairs are divided into two groups of four, with the top two in each section moving into the knockout semifinals.
