Highlights - Nadal too strong for Murray
British number one Andy Murray has sacked his coach Miles Maclagan.
Former professional player Maclagan, 35, joined Murray's team at the end of 2007 as his fifth coach.
Murray is currently in Los Angeles where he is taking part in the Farmers Classic, his first tournament since losing in the Wimbledon semi-finals.
The 23-year-old Scot will continue working with Spaniard Alex Corretja in the run-up to the US Open and review the situation after Flushing Meadows.
His support team will remain unchanged, with strength and conditioning coach Jez Green and physio Andy Ireland alongside him for the US hardcourt season and Matt Little still part of the set-up.
"I've 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," said Murray.
"We have had a lot of success and fun working together."
Maclagan said: "It's been a privilege to work with Andy as his coach and I'm happy to have played my part in his career.
"I also want to thank the team for all their hard work over the years and I will miss working with them and Andy on a day-to-day basis.
"Andy is a great player and I know he will continue to have the success his talent and hard work deserves."
Murray was ranked 11th in the world when he began working with fellow Scot Maclagan in November 2007, after sacking American Brad Gilbert.
Maclagan came in alongside strength and conditioning coaches Green and Matt Little and physio Ireland in what became widely known as 'Team Murray'.
With Maclagan taking the coaching duties, Murray reached his first two Grand Slam finals at the
2008 US Open
2010 Australian Open,
losing on both occasions to Roger Federer, and rose as high as second in the world rankings last August.
However, a first Grand Slam title still eludes him and the defeat in Melbourne was a major blow as
he clearly believed he was about to win his first major.
A slump in form followed and, although it was arrested with an impressive run to the last four at Wimbledon, Murray remains without a title in 2010 and is now fourth in the rankings.
After this week's tournament in Los Angeles, he will play at the Rogers Cup in Toronto and the Cincinnati Masters in the build-up to the US Open, which begins on 30 August.
