Fanboy? You claimed said Saina was in complete control and Okuhara was lucky. Then I proved that match was all about Okuhara's unforced errors and your claim is nonsense. That makes me a fanboy? Hey, let's not spoil good discussion by bringing up facts
Mathias/CP definitely is the favourite but Seo/Chae has a surprise factor too. Hope that it will be a good match
