Anyone who would like to see more female coaches in professional tennis might want to join the Andy Murray fan club.

Volunteer to wear a T-shirt with an “A” on it, and join three others to spell out “A-N-D-Y” while standing in the nosebleed seats at Arthur Ashe Stadium, as some of his fans did at the United States Open last week. Sing his praises between sets, as others did by modifying the pop song “I Want Candy.”

Supporting Murray doesn’t just mean you are pulling for a great player, though he certainly looked like one on Monday when he advanced to the quarterfinals. Supporting Murray also means that you are supporting his decision to choose Amélie Mauresmo as his coach. When he hired her this summer, he broke the stereotype that top men can’t be coached by women, and he said his choice wasn’t about gender, but about finding a good fit.

Murray, who is ranked No. 9 in the world, is a friend to the women’s game. He learned the sport from his mother and has long promoted gender equality in interviews and on Twitter. But supporting female players and succeeding with one as a coach are two different issues.
