What is lob stroke in tennis?

Answer 1

A lob stroke is hit with a low-to-high swing. It is struck to have a high trajectory, well over the height of an opponent at full stretch at the net, and to land near the baseline. A lob can be used defensively, to give oneself time to recover in the point and to force the opponent away from the net, even if the opponent may have an overhead smash as his next shot. Defensive lobs are often hit with underspin. A lob can also be used offensively, to win the point outright. Offensive lobs are often hit with topspin and are especially effective when the opponent's momentum is forward, towards the net. Offensive lobs are more difficult to hit successfully, because of the precise timing required to generate topspin in that motion. Lobs are typically hit as normal groundstokes, but may be hit from a volleying position as well.
