World number one Novak Djokovic brushed aside Switzerland's Stan Wawrinka in straight sets to advance to the semi-finals of the ATP and WTA Cincinnati Masters Friday.
The top-seeded Serb breezed past Wawrinka with little difficulty in just over an hour, winning 6-4, 6-1 to avenge his defeat to the Swiss in the French Open final.
Djokovic will face either Ukrainian qualifier Alexandr Dolgopolov or Czech sixth seed Tomas Berdych in the last four.
In other men's quarter-finals on Friday, Richard Gasquet of France faces Britain's Andy Murray while second seed Roger Federer plays Spain's Feliciano Lopez. – AFP
