Roger Federer moved within sight of a seventh ATP World Tour Finals title on Tuesday when he brushed aside defending champion Novak Djokovic in straight sets.
Djokovic and Federer went into the clash in first and second place respectively in the Stan Smith group after both players had claimed straight-set victories in their opening games on Sunday.
Tuesday’s victory has seen the Swiss move to the top of the standings, ensuring that he reaches the semi-finals irrespective of the result in his last group match against Kei Nishikori on Thursday.
Federer needed 79 minutes to win the match, eventually triumphing with a lopsided score of 7-5, 6-2 to win to take a 22-21 lead in head-to-head clashes with the Serb.
The first set was as evenly matched as expected, but Federer almost went a break up in the very first game, but Djokovic managed to save the break point when called upon.
The breakthrough would come almost 40 minutes later in the 12th game, when Federer capitalised on his second breakpoint in the game to claim the set.
He stretched that run to four games in succession and opened a 2-0 lead in the second set with another break, but Djokovic responded in kind to level the scores at 2-2.
However, those two games would be Djokovic's last of the match as Federer strung together four consecutive games to claim victory.
