Over on the men's side, Roger Federer continued with his roll towards the world number one ranking. The world number two is the only player that can usurp Rafa Nadal at the summit by year's end. And with the Spaniard, taking a pass on this week's tournament -- the Swiss Indoors in Basel -- the 19-time grand slam winner, can close the gap in the rankings. The Artful Roger would take on Frenchman Benoit Paire, an opponent he had never lost to in four previous meetings, and another victory would see him move into the quarter-finals, for the 15th time at the event.

 

Pick things up in the first, and Feds already leading 3-1, and he comes to the net for an easy putaway. He would easily take the set 6-1.  

 

The Frenchman is more competitive in the second, but the Swiss is able to stay on serve as he hits a forehand winner deep into the corner.  

 

And the world number two would break his opponent's next two serves, and seals victory with a foray to the net. Feds wins it 6-1, 6-3 and is into the quarter-finals of the event he has won seven times.

 

Defending champion Marin Cilic at the top of your screen, won the opening set against countryman Borna Coric, but the youngster is able to get the better of his compatriot on this long rally, from the baseline he whips a backhand winner, that earns him a break. He would take the second set 6-3, forcing a decider.  

 

The 2014 US Open champ is able to right the ship in the third, as he comes to the net, and eventually gets the putaway, after a couple of attempts, and would take a 4-3 advantage.  

 

Cilic then breaks next game, and is able to seal victory with an ace on match point and move into the quarters after a three-set triumph.

 

2012 and 2013 winner Juan Martin del Potro at the top of your screen is serving to Julien Benneteau of France, the Argentine took the opener 6-4, and whips a forehand winner to even things at 1 in the second.  

 

The former US Open winner would earn a break later in the frame, and seals victory when his opponent finds the net on this rally to win in straight ones, and move into the last eight. Del Potro still can qualify for the year-ending ATP Tour Finals by winning this event.
