Novak Djokovic, Juan Martin del Potro exchange 'tweeners in Dubai
What's better than one tweener? Two tweeners!
Novak Djokovic and Juan Martin del Potro slipped into exhibition mode during their semifinal in Dubai on Friday, exchanging two between-the-legs shots during a rally, of which only one was actually successful. But forget the trick shots for a minute and check out Del Potro's speed in getting to that second touch volley from Djokovic. Not bad.
