The job of the centre back, centre half, central defender, or stopper is to stop opposing players, particularly the strikers, from scoring, and to bring the ball out from their penalty area. As their name suggests, they play in a central position. Most teams employ two centre backs, stationed in front of the goalkeeper. There are two main defensive strategies used by centre backs: the zonal defence, where each centre back covers a specific area of the pitch, and man-to-man marking, where each centre back has the job of covering a particular opposition player. Centre backs are often tall, with good heading and tackling ability. An ability to read the game well is a distinct advantage. Sometimes, particularly in lower grades of football, centre backs concentrate less on ball control and passing, preferring to merely clear the ball in a "safety-first" fashion. However, there is a long tradition of centre backs having more than just rudimentary footballing skill, enabling a more possession-oriented playing style. Centre backs usually remain in the half of the field that contains the goal they are defending, but tall defenders will often go forward to the opposing team's penalty box when their team takes corner kicks or free kicks, where scoring with one's head is a possibility.
