The game of tennis may seem very simple , easy and fun on t.v but in reality , it simply isn't so easy. One of the main reasons that make this game so attractive and interesting is that the players put their entire bodies on the line while they are on the court. Every player that gets out on the court is ready to give his 100% . Every player is in it to win it.
In this effort of defeating their opponents , players are ready to cross every limit and try every possible (legal) way of returning the ball to the other side of the court . It is this effort that leads to players playing innovative shots.
One of the most innovative and the toughest shots to play in tennis is "The Tweener".
