Andy Murray's new status as US Open champion will see off-court earnings boom Andy Murray can expect to treble his off-court earnings to around £20 million a year after his US Open triumph, industry analysts have predicted. Murray's commercial activities earn him around £6 million annually and those figures will swell by £2 million because of built-in performance bonuses after his victories at the Olympics and Flushing Meadows. "This is the final leap he had to make up the commercial ladder and he will be worth three times more off the court than before," said Nigel Currie, of brandRapport, a sponsorship consultancy. If he stays at the top with at least one grand slam each year his potential will keep going. It does help that he's made his breakthrough at the US Open because that gives access to the US market. They like Celts and they're particularly partial to Scots. Winning in New York raises his profile over there. It is a big market that is tough to crack. The commercial demands on players were illustrated when Murray was seen panicking after his win over Novak Djokovic when he was unable to find the watch his sponsor, Rado, requires to wear. His girlfriend Kim Sears told him it was in his bag. Murray's agent, Simon Fuller at XIX Management, which also looks after David Beckham and Lewis Hamilton, had planned ahead for an eventual grand slam triumph for Murray. Earlier this year the sponsorship Highland Spring expired. There were a number of offers from firms hoping to take over the rights to his left-arm badge but all were turned down. "XIX wanted something that would be reflective of the value he'd reach as a grand slam winner," said a source close to Fuller. It needed to be a global sponsor and one who could work with his schedule internationally. Yesterday that potential sponsor learnt more of Murray the man as he embarked on a dizzying round of interviews, beginning with the CBS This Morning show and moving on to the Today programme on NBC.
