Djokovic battles through

Novak Djokovic was given a work-out before earning his ninth straight win over Marin Cilic to move into the fourth round of the French Open.

Djokovic was not at his best as he battled to a 6-3 6-2 6-7 (2-7) 6-4 victory to preserve his unbeaten record against Cilic.

The Croatian started strongly, moving into a 3-1 lead before Djokovic won out to take the opening set.

Even then, Djokovic was guilty of unforced errors and allowed Cilic to break back in the fourth set after taking a 4-2 lead.

The match took more than three hours to complete, but Djokovic eventually emerged with a win which will see him face either world number 14 Jo-Wilfried Tsonga or 22nd seed Jerzy Janowicz in the next round.
