The bowling crease is a line marked on a cricket field that indicates the area where the bowler must deliver the ball. It is located 4 feet in front of the stumps and is crucial for maintaining fair play. If a bowler oversteps this line while delivering the ball, it results in a no-ball, giving the batting team an extra run. This crease is part of the larger set of markings on a cricket pitch, which also includes the popping crease and the return crease. Each of these creases serves specific purposes in the game, helping to regulate the actions of both the bowler and the batsman.
