MASON, Ohio, Aug 17 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.
World number one Roger Federer, who dealt with American
Mardy Fish 6-3 7-6 in some style, will play his Swiss Davis Cup
team mate Stanislas Wawrinka in the other semi.
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.
"It was my best match so far here in this tournament and
came in the right moment, really," Djokovic, who had an easy
passage through to the last eight after Russian Nikolay
Davydenko retired injured during their match, told reporters.
"I had the biggest challenge today with Cilic who has been
playing well the last couple of months and I played a really
The five-times grand slam winner may have added incentive on
Saturday given Serbia's Davis Cup semi-final loss to Argentina
last year in which Djokovic retired against Del Potro.
"All these losses made me stronger and, yes, they are
difficult, especially when you're playing for a country and when
you're in Olympic Games and we're fighting for bronze medal,"
"He won that match. It happens. It's a sport. You lose, you
win, but the most important thing is to try to move on and
become even better and even stronger from those experiences and
try to win."
Del Potro overcame the surprise player of the tournament,
Frenchman Jeremy Chardy, who entered the draw as a lucky loser
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.
Four-times Cincinnati winner Federer broke in the first and
final game of the first set, looking in good shape against Fish,
a hard court specialist who finished runner-up to the Swiss in
the 2010 final.
Fish stuck at his task in the second set but the world
number one turned it up a notch in the tie-break which he won to
"I'm very pleased that I was able to play at a high level
and keep there throughout the match," said Federer, who now
comes up against compatriot and friend Wawrinka.
Wawrinka, ranked 26th in the world, beat big-serving
Canadian Milos Raonic 2-6, 7-6, 6-4.
After making the most of his only break point opportunity
early in the third set, Wawrinka then saved two at 4-3 before
wrapping things up in his next service game.
"I'm playing great tennis after two tough months. I lost in
the first round at Wimbledon, Gastaad and the Olympics and it
wasn't easy, but I am glad to be back on the hard court," he
