Marray said "I played in a qualifying match in Nottingham just before Wimbledon, and I wasn't even trying to win the match. I just wanted off the court. I was 29 years old and I thought, if I'm doing that, what am I even doing playing tennis? It was quite emotional."

This also raised his doubles ranking to a career-high no. 21 in the world. This was the first time Marray broke into the top 50 in the rankings, making him Britain's No. 1.
