OK it is a known fact that within Justine's camp of her, Carlos and Pierre, there are certain roles. Not sure who the husband is but
Carlos is the coach. Pat comes in as the fitness trainer. Pierre is supposedly sometimes Justine's hitting partner on the court. He is always wearing Adidas clothing anyway as if he is a pro.
But has anyone ever seen Pierre's skills on the tennis court? I mean is he a capable hitting partner for Justine that can switch between stimulating the play of Lindsay / Venus to Patty Schnyder at the turn of a switch? Or is he an amaeteur?
