LONDON (AFP) World number four Andy Murray has sacked his coach Miles Maclagan, his management company 19 Entertainment said on Tuesday. Former professional player Maclagan, 35, had been on Murrays coaching team for two and a half years. Murray, 23, is currently competing in Los Angeles in the Farmers Classic, his first tournament since his Wimbledon semi-final loss to Rafael Nadal. For the time being, the Scot will work with former Spanish star Alex Corretja pending the appointment of a new coach. Ive had a great relationship with Miles over the past two and a half years and I want to thank him for his positive contribution to my career, Murray said in a statement. Maclagan said: Its been a privilege to work with Andy as his coach and Im happy to have played my part in his career. Andy is a great player and I know he will continue to have the success his talent and hard work deserves. Murray arrived at the University of California Los Angeles tennis facility in the late afternoon Tuesday and practised but did not speak to reporters. The number one seed received a bye through the first round so his first match wont be until later in the week against American qualifier Tim Smyczek. Murray is still waiting to break his Grand Slam duck despite several near misses and former coach Mark Petchey said the Scot doubtless felt he needed fresh input. Theyve just got to the end of the road, Petchey, Murrays coach from 2005 to 2006, told Sky Sports News. Petchey said things had gone a little bit south for Murray this season, prompting the Scot to look elsewhere to galvanise his game. Maclagan began working with Murray in late 2007, replacing Brad Gilbert.
