Andy Murray crashed out of the Miami Open last night, making it a mixed weekend for the family.
Elder brother Jamie Murray will become world number one doubles player next month, the first Briton since Virginia Wade in 1973 to hold the ranking.
The 30-year-old will replace Brazil’s Marcelo Melo on 4 April when the rankings are next updated.
His younger sibling, the world number two men’s singles player, was subject to rumours of a split with coach Amelie Mauresmo after his 6-7(1), 6-4, 6-3 defeat to Bulgarian Grigor Dimitrov in the third round of the Miami Open.
Mauresmo watched on from a different part of the stadium to the box where the rest of Murray’s team and family were located. But Murray rubbished talk of a rift with his French coach.
The Scot, who received a violation from the umpire for smashing his racket during the second set, insisted that Mauresmo sat elsewhere in a bid to control his on-court tantrums.
“I’ve just been trying to find different ways to improve my focus on the court,” Murray said in his post-match press conference.
His brother Jamie is arguably in better form after winning his first Grand Slam men’s doubles title in January, securing the Australian Open with his Brazilian partner Bruno Soares.
Jamie is poised to become number one just 12 months after being consigned to the nether regions of the world rankings.
Melo said: “He really deserves it. He made the final in Wimbledon, final US Open, won the Davis Cup, won the Australian Open, so he deserves it a lot. I’m happy for him.”
Computerised rankings were introduced by the ATP for singles in 1973 and for doubles in 1976. The WTA introduced computer rankings for singles in 1975 and doubles in 1984.
