Home favourite Novak Djokovic won the inaugural Serbia Open with a straight-sets victory over surprise finalist Lukasz Kolbat in Belgrade.

World number three Djokovic was playing in his fifth ATP final of the season and could have been forgiven for expecting an easy ride against Pole Kolbat, ranked 179 and making his first ATP final appearance after a shock semi-final victory over Ivo Karlovic.

And so it appeared during the first set, the Serb breaking his opponent almost immediately on the way to a comfortable 6-3 triumph.

But Kubat then gave Djokovic a dose of his own medicine by breaking him early in the second to open up a 3-0 lead and the top seed had to fight back to take it to a tie-breaker.

Djokovic demonstrated his class from thereon though, cruising to victory in the tie-break without dropping a point to wrap up the match and become the first Serbia Open champion.
