Novak Djokovic through to Cincinnati Open final

Novak Djokovic has reached the final of the Cincinnati Open thanks to a straight-sets victory over Juan Martin del Potro.

The match was a repeat of the recent bronze medal contest at the London Olympics, which Del Potro won.

However, Djokovic gained a degree of revenge this time thanks to a 6-3 6-2 triumph.

The Serbian world number two will meet either Roger Federer or Stanislas Wawrinka in Sunday's final.
