The between the legs shot in tennis is one of the most exciting in all of sports, not just because of the sheer difficulty but just because even the pros never know what is really going to happen.
We've seen tweeners slam into the net, fly well over the court, but also catch lines, win big points and bring crowds to their collective feet.
On Wednesday at the Western & Southern Open, Juan Martin del Potro hit a different type of tweener in his win over Nikolay Davydenko. It was a tweener with touch.
Potro went between the legs, but without the power you usually see, carrying Davydenko's head for the winner and the shot of the week so far in Cincinnati.
