Novak Djokovic got the better of Taylor Fritz, while Wimbledon champion Carlos Alcaraz had to push hard to get past Max Purcell on Friday as the top two seeds reached the semi-finals at the ATP/WTA Cincinnati Open.

Tournament No. 2 Djokovic showed no mercy against Fritz, hammering the top American 6-0, 6-4 to improve to 7-0 against him.
