Frenchman Gael Monfils did not concede one ace against 6' 10'' Ivo Karlovic in a 7-6(8), 6-1 win over the Croatian. It was the first time in Karlovic's 225-match ATP career that he had failed to serve an ace in a match.
Monfils, who has not won a tournament since his first ATP title in Sopot almost three years ago, had won just two matches this season before arriving in Monte Carlo.
Monfils said: "I was stressed about Karlovic's game because I wanted to make him play as many balls as possible because I know he's not so good at that. But thinking about that stressed me, and I played too short."
Monfils said he played better when he decided to become more aggressive. "I wanted to take risks and I wanted to take advantage of some of his weaknesses."
