Roberto Bautista Agut posed plenty of problems for Novak Djokovic, but the top seed at Roland Garros eventually prevailed in four sets.
Novak Djokovic overcame the spirited resistance of Roberto Bautista Agut on Wednesday to book his place in the quarter-finals of the French Open.
Bautista Agut claimed the first set on Tuesday prior to a rain delay, only for Djokovic to level the match and open up a 4-1 advantage in set three before further showers forced the match - which had initially been scheduled for Monday - into a second day.
The world number one broke at the first time of asking when play resumed on Court Philippe Chatrier, courtesy of a stunning cross-court forehand winner, and held serve in the next game to move two sets to one up.
Yet Djokovic did not have things all his own way as he completed a 3-6 6-4 6-1 7-5 triumph, with the athletic Bautista Agut briefly claiming a two-game lead in set four.
Having played two fantastic points under pressure to deny Djokovic a break, Bautista Agut opened up a 4-2 advantage when the Serbian followed a missed overhead by sending a backhand long.
However, the underdog faltered in the next game and Djokovic, who utilised the drop shot on a regular basis, soon claimed a second break.
Bautista Agut again showed his quality and character by saving a match point at the end of a lengthy rally, but the top seed was not to be denied and will now face either David Ferrer or Tomas Berdych in his 28th successive grand slam quarter-final.
