Andy Murray hopes to step up his competitive return from hip surgery after confirming on Wednesday that he will play next week's Citi Open doubles event with his brother Jamie.
The Washington DC tournament will be the younger Murray's fourth tournament since undergoing hip resurfacing surgery in January and his first on a hard court.
The Scot lost in the second round of the men's doubles at Wimbledon with Pierre-Hugues Herbert and in the third round of mixed doubles with Serena Williams, but said there was still a long way to go before a return to singles competition.
The Murray bothers last played together at the 2016 Rio Olympics, and were a prolific partnership when Britain won the Davis Cup in 2015.
"I'm obviously very excited to be on the court with him (Jamie) and also to go back to Washington," Andy said in a statement.
"It's a city I've always enjoyed visiting so it should be fun. I'm hoping to have a good summer over in the States, keep progressing physically and hopefully get back on the singles court soon."
The doubles field at the Citi Open also includes the first-time partnership of Greek Stefanos Tsitsipas, ranked world number six in singles, and Australian Nick Kyrgios.
