About smash

A smash in tennis is a shot that is hit above the hitter's head with a serve-like motion. It is also referred to as an overhead. A smash can usually be hit with a high amount of force and is often a shot that ends the point. Most smashes are hit fairly near the net or in mid-court before the ball bounces, generally against lobs that have not been hit high enough or deep enough by the opponent. A player can also smash a very high ball from the baseline, generally on the bounce, although this is often a less forceful smash.
