Djokovic to face Del Potro in Cincy semis

Novak Djokovic will play against Juan Martin del Potro in the Cincinnati Open semi-finals today.

Nole scored a 6-3 6-2 victory over Marin Cilic while Delpo beat Jeremy Chardy 6-1 6-3.

"It was my best match so far here in this tournament and came in the right moment, really," Djokovic said.

"I had the biggest challenge today with Cilic who has been playing well the last couple of months and I played a really good match."

The Serb may have added incentive today 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," said Djokovic.

"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 Chardy in just 76 minutes. He surrendered only 12 points on serve and broke Chardy four times.
