Djokovic trounces Poland's Kubot to make last eight

MELBOURNE (Reuters) - Former champion Novak Djokovic charged into the quarter-finals of the Australian Open Monday, thrashing Poland's Lukasz Kubot 6-1 6-2 7-5.

Kubot, who was given a walkover in the previous round after Russia's Mikhail Youzhny pulled out injured, was completely outclassed by Djokovic, who committed only 17 unforced errors in wrapping up the match in less than two hours.

The 86th-ranked Pole offered belated resistance in the third set, but Djokovic broke him at 5-5, then sealed victory on the second of three match points with an imperious forehand winner.
