Novak Djokovic took a nasty spill during a tight first set but then pulled away and beat Joao Sousa 6-4 6-1 on Sunday in the third round at the Miami Open.

Djokovic slipped and fell on his left side behind the baseline as he hit a running forehand into the net to lose serve, making the score 4-all.

But he rose unhurt and soon took charge of the match, losing only 11 points in the final eight games.

Seeded No.1, Djokovic is bidding for his sixth Key Biscayne championship, which would tie Andre Agassi’s men’s record.

Serena Williams is seeking her ninth title.
