Former world No. 4 Greg Rusedski thinks playing the US Open might be a "step too soon" for Andy Murray as the three-time Grand Slam champion is just returning to singles action. Murray, 32, accepted a wildcard into the Cincinnati Masters to play his first singles event since undergoing a hip resurfacing surgery at the end of January.
The former world No. 1 has also announced that Zhuhai and Beijing will be his first two events after the US Open. Murray will officially makes his return to singles action when he clashed against France's Richard Gasquet in the Cincinnati first round.
"This all sounds logical, but I think the US Open might be a step to soon not having played a singles match yet and playing 3/5 set matches. He will probably play doubles at the Open and continue training. Going to be very interesting to see how he plays against Gasquet this week," Rusedski said on Twitter. Murray has played five doubles tournaments since making a comeback in June at the Queen's Club.
