Grigor Dimitrov and Peter McNamara have ended their coaching relationship, the Patrick Mouratoglou Academy reported. The two were together for a year-and-a-half, and the Aussie McNamara helped the Bulgarian reach a career-high No. 52 ranking. Patrick Mouratoglou says that the academy will take its time in hiring a new coach for Dimitrov, who has the nickname "Baby Federer."

Mouratoglou just hired five-time Grand Slam champion Martina Hingis to work with his young women players, but she will not work with former Top 15 player Yanina Wickmayer for the moment, who is being helped by the academy.
