Long hop

Long hop is a type of slow serve in cricket characterized by a fairly short bounce. It would seem that the batsman has time to observe the ball’s direction and determine the option for its reflection. However, it is not.
Long Hop: Basics
It is difficult to defend against a fast ball that falls close to the batsman but bounces low. With this serve, the batsman often anticipates that the ball will be delivered fast or with a spin, which is the opposite of what they anticipate. Under these circumstances, the batsman is at danger of being knocked out of the game.
While it is a worry that such a ball should bounce over the wicket when it is passed, it is important to note that this is not always true.
