Andy Murray split with part-time coaching consultant Alex Corretja and will try to halt the worst skid of his career.
The fifth-ranked Murray has worked with Corretja since 2008 in a bid to improve his clay-court game, but the pair have mutually agreed to end their relationship. The Scottish player is heading into the clay-court season after getting knocked out in opening matches at Rotterdam, Indian Wells and Miami.
"I have learned so much from being around him and I want to thank him for his hard work, enthusiasm, dedication and support," Murray said on his website. "He has been a great friend as well as a mentor to me and we've shared lots of success and good times on and off the court."
Murray reached three Grand Slam finals and won six Masters Series events in his three years with Corretja, but failed to land an elusive major.
British media reported Monday that eight-time major winner Ivan Lendl would be interested in coaching Murray.
