Crease (cricket)
（重定向自Popping Crease）
In the sport of cricket, the crease is a certain area demarcated by white lines painted or chalked on the field of play, and pursuant to the rules of cricket they help determine legal play in different ways for the fielding and batting side. They define the area within which the batsmen and bowlers operate. The term crease may refer to any of the lines themselves, particularly the popping crease, or to the region that they demarc. Law 9 of the Laws of Cricket governs the size and position of the crease markings, and defines the actual line as the back edge of the width of the marked line on the grass, i.e., the edge nearest to the wicket at that end.
