I just have a hard time visualizing Thai upsetting anyone late into the tournament. If it gets into a third set, I def. don't see him winning (mentally fragile).
Thai has never lost to Rubin. That might help his mental state. Rubin competes better for now, although I have seen him check out when things don t go his way. Thai is a better tennis player but sometimes that s not a guarantee for coming up with a win.
