No, there probably isn't; she has never claimed to be a tennis "player".

Judy explained that when her 2 sons first showed an aptitude for tennis, facilities to train were few and far between in Scotland, and she knew if they were to reach their potential it was down to her to do something about it. So she set about learning just about everything she could about the game, so that she could be the boys' coach. Considering how far Andy - particularly - reached before going to other coaches, I would say she has done a pretty amazing job. Would that I had had such a mother!

I read that Judy felt responsible for the destruction of Jamie's singles career by the LTA

and it was Andy's decision to join the Spanish tennis academy after a chance conversation with Nadal (and after seeing what had happened to his older brother) that is largely credited for his successful development into a top player
