MASON, Ohio, Aug 17 (Reuters) - World number two Novak
Djokovic has a shot at revenge against Juan Martin del Potro,
who ended the Serb's medal hopes at the London Olympics, when
the two clash in the Cincinnati Open semi-finals on Saturday.
Djokovic, who lost to former U.S. Open winner Del Potro in
the Olympic bronze medal match less than two weeks ago, enjoyed
a routine 6-3 6-2 victory over 12th seeded Croatian Marin Cilic
on Friday to advance.

and reached the quarter-finals thanks to wins over American Andy
Roddick and Olympic champion Andy Murray.
The tall Argentine needed just 76 minutes to make sure
Chardy's run stopped, surrendering only 12 points on serve and
breaking Chardy four times in a 6-1 6-3 rout.
In other quarter-final action, Switzerland's Stanislas
Wawrinka faces Canadian Milos Raonic, while world number one
Roger Federer goes against American Mardy Fish.
