MIAMI (AFP) - World number one Novak Djokovic advanced to the quarter-finals of the ATP and WTA Miami Open on Tuesday by defeating Austrian 14th seed Dominic Thiem 6-3, 6-4.

Two-time defending champion Djokovic, a five-time Miami winner overall, reached a last-eight date Wednesday against Czech seventh seed Tomas Berdych, who ousted French 10th seed Richard Gasquet 6-4, 3-6, 7-5.

Berdych has won only two of 24 meetings with Djokovic, having lost their past nine matches since a 2013 Rome quarter-final triumph.
