Non-striker

According to the Cricket Laws, two batters should almost always be present on the field during the batting team’s serve. The player who is referred to as a striker is the one who hits serves, whereas the one who is placed on the other side of the field is a non-striker.
The task of the non-striker in cricket is to protect the second wicket (he does not take the serve, just stands near it). Furthermore, following a successful hit, he assists the striker in accumulating runs by assisting both players in running from one wicket to the second over.
If a striker is eliminated from the game during a match, a non-striker takes his place and prepares to take the serves. Additionally, the next batter enters the field, and he instantly takes the position of the striker. Keep in mind that the inning is over when the bowling team has successfully struck out ten of the eleven strikers. The eleventh hitter is unable to strike balls since he does not have a pair of wickets (one wicket is still unprotected).
