Re: Radwanska: I gave Caroline a present so I hope she buys me one too!
Sorry, but this is tennis. It's a ruthless business. You do what you need to do to win, as long as your actions don't directly hurt someone else. "Friendships" with other players only go so deep. Wozniacki was obviously going to be happy that she was through to the semis, and that happiness is going to trump concern for her friend.
