Defending champion Novak Djokovic  tackles Argentine Juan Martin Del Potro  in the quarter-finals of the US Open with a place in the last four at stake. The world number two has been untested in his opening four matches at the event, scoring three straight sets  wins in the opening week. Two sets and a break up against Stanislas Wawrinka in his last match, the Serbian was then gifted a quarter-final spot when his opponent was forced to withdraw from the event with an illness.

Del Potro, the 2009 US Open champion, hasn’t found things as easy in the tournament. 20 year-old American Ryan Harrison took a set off the world number eight in the second round, as did retiring veteran Andy Roddick in the fourth round matchup between the pair.

While Djokovic holds a 5-2 career advantage over Del Potro, both of the Argentines wins have come in recent meetings between the pair. While the Serbian triumphed in last month’s semi-final showdown at the Cincinnati Masters, Del Potro scored a straight sets win over his opponent at the London Olympics and was also declared the winner when up a set and a break before Djokovic retired in last year’s David Cup tie between Argentina and Serbia.

The winner of that match will meet either Janko Tipsarevic  or David Ferrer  in the semi-final, with their quarter final clash set to be played earlier in the day. Both Djokovic and Ferrer will be looking to avoid being upset in the quarter-finals, after world number one Roger Federer was knocked out of the tournament by Tomas Berdych and Andy Murray was forced to come from behind against Marin Cilic in the top half of the draw.
