All bowlers are classified according to their looks or style. The classifications, as with much cricket terminology, can be very confusing. Hence, a bowler could be classified as LF, meaning he is a left arm fast bowler; or as LBG, meaning he is a right arm spin bowler who bowls deliveries that are called a "leg break" and a "Googly".
During the bowling action the elbow may be held at any angle and may bend further, but may not straighten out. If the elbow straightens illegally then the square-leg umpire may call no-ball. The current laws allow a bowler to straighten his arm 15 degrees or less.Fielding positions in cricket for a right-handed batsmanFieldingMain articles: Fielder and Fielding strategy (cricket)
All eleven players on the fielding side take the field together. One of them is the wicket-keeper aka "keeper" who operates behind the wicket being defended by the batsman on strike. Wicket-keeping is normally a specialist occupation and his primary job is to gather deliveries that the batsman does not hit, so that the batsmen cannot run byes. He wears special gloves (he is the only fielder allowed to do so), and pads to cover his lower legs. Owing to his position directly behind the striker, the wicket-keeper has a good chance of getting a batsman out caught off a fine edge from the bat. He is the only player who can get a batsman out stumped.
Apart from the one currently bowling, the other nine fielders are tactically deployed by the team captain in chosen positions around the field. These positions are not fixed but they are known by specific and sometimes colourful names such as "slip", "third man", "silly mid on" and "long leg". There are always many unprotected areas.
