World number four Andy Murray has parted company with his coach Miles Maclagan to end their working partnership after almost three years.
Maclagan, 35, began working with the Scot at the end of 2007 to replace Brad Gilbert.
Alex Corretja later came on board and he will continue to work with the 23-year-old, who is in Los Angeles where he is competing in the Farmers Classic, his first tournament since losing in the semi-finals at Wimbledon.
Murray will review the situation after the US Open which is now a little over a month away.
In a statement issued by Murray’s management company, 19 Entertainment, the player said: “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.
“We have had a lot of success and fun working together.”
Maclagan, a former British Davis Cup player, added: “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.”
Under Maclagan, Murray reached the finals of the US Open in 2008 and the 2010 Australian Open, losing to Roger Federer on both occasions.
The Dunblane-born player also made two Wimbledon semi-finals as well as the last eight in 2008.
In September 2009, Murray reached a career-high ranking of world number two.
