Djokovic too good for Berdych again at Miami Open

The Serbian world number one made it 23 wins in 25 matches against Czech Berdych, claiming a 6-3 6-3 victory to move into the last four on Wednesday.

The win was also Djokovic's 10th consecutive over Berdych, an incredible streak dating back to 2013.

A Berdych victory never looked likely at the ATP 1000 event, broken on his opening two service games to be immediately on the back foot.

Djokovic, a two-time defending champion in Florida, broke in the opening game of the second set.

He required a medical timeout for treatment on his back before closing out his victory in one hour, 40 minutes.

Awaiting him in the last four is David Goffin, who beat Gilles Simon earlier in the day.
