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.
