Marking the Crease: How Batsmen Use the Crease Line During Play
How batsmen use the crease lines during play — the popping crease as the safe zone for the batsman, how batsmen 'ground' their bat to be safe from run-out, the practice of marking a scratch position with the bat at the start of an innings, why batsmen lift their bat at the bowler's end before being 'in', and the DRS technology that reviews bat/crease position in close run-out decisions.
The Popping Crease as Safety Zone
The popping crease is the batsman's safety line — when any part of the batsman's bat or body is grounded behind the popping crease at the striker's end, the batsman cannot be stumped or run out at that end. 'Grounded' means physically touching the ground behind the line: the bat can be pressed flat on the ground, dragged along the ground as the batsman slides in, or simply tapped down with the toe. The bat's toe (the bottom of the blade) must be behind (not on or over) the crease line for safety — touching the line is not sufficient. This is why batsmen slide their bat along the ground when completing a run: sliding the bat onto the crease before their body necessarily crosses ensures they are 'in' even if they continue sliding forward.
Marking and Reference
When a batsman takes guard (lining up their bat with a specific stump), they mark the crease by scratching a visible line with the bat's spike or edge at that guard position. This scratch mark gives them a visual reference to return to on every subsequent delivery — even after being hit and moving away from the crease, or after a run, the batsman returns to their marked position. Pitches accumulate multiple scratch marks from different batsmen across the day's play, making the specific batsman's mark sometimes unclear — some batsmen use distinctive markings (a cross, a T-shape) to identify their personal guard mark among the general wear. This marking is legal and standard practice at all levels of cricket.
The Non-Striker's Crease
The non-striker (the batsman at the bowler's end) must also be in their crease until the ball is bowled to be safe from a Mankad (run-out of the non-striker by the bowler before releasing the ball). Non-strikers increasingly back up (move forward from their crease) as the bowler approaches the crease — they leave at the legal moment (when the bowler's front foot lands, the ball is released) and take as much ground advantage as possible toward the striker's end. A non-striker who backs up too early (before the bowler's arm has reached the ball-release point) can be run out by the bowler — the Mankad dismissal. The non-striker's crease behaviour is closely watched in modern cricket following high-profile Mankad incidents.
Frequently asked questions
Can a batsman be run out if they dive and their bat skids past the crease?
If a batsman dives with their bat and the bat skids along the ground past the crease line (crossing it), the batsman is in as long as the bat made ground contact behind the line before crossing (the bat touched the ground on the safe side). The question is whether at any point the bat was grounded behind the line while the stumps were intact. If the batsman dives but the bat never touches the ground behind the line (the bat goes over the line without contacting the ground behind it), the batsman is run out. In practice, a sliding batsman who reaches the crease with their bat along the ground is safe from the moment any part of the blade contacts the ground behind the crease — the momentum that carries the bat further is irrelevant.
Does a batsman need to ground their bat at both ends when completing a run?
The batsman must ground their bat (or body) at the destination end — the end they are running toward — before the stumps are broken at that end for the run to be safely completed. They do not need to ground at both ends — only at the end they arrive at. The batsman who runs from the striker's end to the non-striker's end needs to ground at the non-striker's end; the non-striker who runs to the striker's end needs to ground at the striker's end. The run is scored once the batsmen have both crossed (or the second one reaches their destination). A run is not cancelled if a batsman fails to ground at the end they came from — only the destination grounding matters for run-out safety.
What happens if the crease line becomes unreadable during play?
Crease lines are painted on the pitch before play and are visible for the duration of a match under normal circumstances. The lines can become less distinct in very wet conditions (rain can wash paint) or after heavy use in a high-traffic area (the area around the popping crease gets heavy foot and bat traffic). If a crease line becomes unreadable, groundstaff can refresh it during an interval — matches are not stopped specifically to repaint lines. Umpires use their judgment if a crease line is unclear: the law requires the batsman to ground their bat behind the line's original position even if the paint is worn. Players cannot claim safety based on the line's invisibility — the line's position is fixed regardless of its painted visibility.
