Re: Who is coaching Hingis?
She doesn't really explain her coaching situation these days, only that she wants to make most of her decisions herself.
That Radem guy they showed sitting in the stands is her hitting partner, not her coach. I suspect Melanie is still doing some coaching but not obviously on a full time basis, as she is operating her academy back in Zurich.
I suspect Martina has no full time traveling coach and doesn't want one.
