Well, sometimes its hard to tell who has a real clothing sponsor or who just has a supplier. Mandy Minella for example now wears Nike because she has a deal with Tennis-Point...does that mean she has a clothing deal? Not really, imo.
I think it's absolutely crazy that Mona Barthel has no deal yet, it would be completely justified both by ranking and talent.
Well, Radwanska still has no proper deal that would be worthy of a Top 5 player, I highly doubt Lotto pays anywhere close to what Nike and Adidas shed out. But somehow she doesn't seem to fit their mold.
Peak Pierce was like number 5 in the world in 2005 and didn't have neither a clothing nor a racquet sponsor Knowing her she probably asked about 10 million bucks at least for each though.
She is part of the German tennis revolution but unfortunately is of the lower tier. Either it's Nike (but Sabine) or Adidas (but Petkovic). I can't imagine smaller clothing companies picking her up unless she does better this year because the German market is dominated by the two sporting giants. :shrug:
