World No 6 Milos Raonic and coach Richard Krajicek have decided to part ways after just six months working together, the Canadian announced after a fourth round exit from the French Open.
Since beginning work with the former Wimbledon champion in December, Raonic has played in nine tournaments and reached the final in two tournaments but has not won a title yet.
At Roland Garros, Raonic could not go long and lost to world No 20 Pablo Carreno Busta in the fourth round.
He will next be in action during the Aegon Championships in Birmingham, later this month.
