Sometimes when Sharapova is stretched out wide to her backhand, she will take the right arm off and hit a left-handed forehand lob. Will any ambidextrous pro come onto the tour and perhaps even dominate by hitting heavy topspin forehands off of both wings? There would be no backhand to attack (duh) - and the forehand in general seems to have more options for most people - in terms of flattening it out with more power, hitting with more spin to hook people off of the court, and stretching out a bit further when on the defensive. If someone had all of these options on both wings, wouldn't he be unstoppable? Especially if his right handed and left handed forehand were both as good as Federer's/Nadal's forehand?
