World number one Novak Djokovic fought back to beat Tallon Griekspoor 4-6 7-6(2) 6-4 on Thursday and reach the Paris Masters quarter-finals.
The Serb, unlike in his slick second-round win, looked rusty in only his second singles match since playing in the Davis Cup six weeks ago, losing a 4-1 lead in the first set and squandering three break opportunities early in the second.
The 24-times Grand Slam winner mounted a comeback, however, as he convincingly won the tiebreak and took the decider to continue his quest for a record-extending seventh title in Paris.
