Tactical Considerations
The variations in different types of delivery, as well as variations caused by directing the ball with differing line and length, are major weapons in a bowler's arsenal. Throughout an over, the bowler will choose a sequence of deliveries designed to attack the batsman's concentration and technique, in an effort to get him out.
The bowler also varies the amount of loop and pace imparted to various deliveries to try to cause the batsman to misjudge and make a mistake. As the crease has a width, the bowler can change the angle from which he delivers to the batsman in an attempt to induce a misjudgement.
Usually, the bowler decides what type of delivery to bowl next, without consultation or even informing any other member of his team. Sometimes, the team captain will offer advice or even issue a direct order regarding what deliveries to bowl, based on his observations of the batsman and the strategic state of the game. Another player who occasionally offers advice to the bowler is the wicket-keeper, since he has a unique view of the batsman and may be able to spot weaknesses of technique.
Another piece of information important for the bowlers to consider prior to their deliveries is the state of pitch. The pitch is a natural ground and its state is subjected to variation over the course of the cricket, some of which are multi-day events such as test matches. Spinners find an old pitch, one that hasn’t been frequently utilized, more suitable to their deliveries rather than a fresh pitch, one that hasn’t come under use as much such as a pitch at the start of the match.
