In-form Novak Djokovic beat Tomas Berdych to win his second Monte Carlo title and become the first man to win the opening three Masters events of the season. The world number one came through 7-5 4-6 6-3 on the clay to extend his winning run in 2015 to 17 matches. Djokovic, 27, adds Monte Carlo to the Masters titles he won in Indian Wells and Miami last month. The Serb hopes to complete the career Grand Slam with a first title at the French Open, which starts next month. “I think the most important period of the year is coming up right now,” said Djokovic. “Obviously Roland Garros and Wimbledon are the priority. that’s where I want to perform my best, but we’ll take it step by step and see how far I can go.” Djokovic had laid down a marker with victory over nine-time Roland Garros champion Rafael Nadal in the semi-finals and completed the job in Sunday’s rain-interrupted final.
