Novak Djokovic reaches Cincinnati Open semi-finals

Novak Djokovic has eased his way into the semi-finals of the Cincinnati Open following a straight-sets win over Marin Cilic.

The Serbian broke the Croatian 10th seed early on his way to taking the opening set 6-3.

The world number two broke twice more in the second as he closed out the match 6-2 in comfortable style.

Djokovic will now play Juan Martin del Potro for a place in the final after the sixth seed saw off Andy Murray's conqueror Jeremy Chardy earlier in the day.
