Novak Djokovic beat Tomas Berdych 7-5, 4-6, 6-3 to win the Monte-Carlo Rolex Masters title.
Nole improved to 52-23 in tour-level title matches and erned €628,100 and 1,000 ATP Rankings points.
"It was a battle," Djokovic said. "I was up a set and 3-2, then a (rain) interruption, we came back, I had a break point but he played some amazing shots. If I made the break there, maybe the match could be done in two sets.
"He had his chances as well. The third set started very well at 4-0. I just lost that service game for no reason. After that, every single game went the distance: deuce, advantage. It was a real fight. I was trying to mentally stay tough and fight my way through."
