But Djokovic very nearly lost his cool when, two sets up and 2-1 up with a break in the third, the world number one paused before serving as a fan heckled him from the right side of his service court.
But the warning wasn’t enough for Djokovic, who made his feelings very clear to the umpire.
“Every single serve, it’s the game guy!” He complained as he pointed out the offending spectator in the stands at Court Suzanne Lenglen.
“First serve, second serve. Every single serve!”
A heckler then disturbed Cuevas during his service game, and earned a stern look from Djokovic, who looked angry on behalf of his opponent, who went on to hold serve.
But, despite Cuevas’ stubborn resistance, Djokovic’s class proved too much as he served out the match to claim the straight-sets victory, 6-3, 6-2, 6-4, and head into the third round of the tournament, where he will face Lithuania’s Ricardas Berankis.
