Bowling (cricket) in the context of "Radar gun"

Cricket is a bat-and-ball game that is played between two teams of eleven players on a field, at the centre of which is a 22-yard (20-metre; 66-foot) pitch with a wicket at each end, each comprising two bails (small sticks) balanced on three stumps. Two players from the batting team, the striker and nonstriker, stand in front of either wicket holding bats, while one player from the fielding team, the bowler, bowls the ball toward the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball with the bat and then switch places with the nonstriker, with the batting team scoring one run for each of these swaps. Runs are also scored when the ball reaches the boundary of the field or when the ball is bowled illegally.

The fielding team aims to prevent runs by dismissing batters (so they are "out"). Dismissal can occur in various ways, including being bowled (when the ball hits the striker's wicket and dislodges the bails), and by the fielding side either catching the ball after it is hit by the bat but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease line in front of the wicket. When ten batters have been dismissed, the innings (playing phase) ends and the teams swap roles. Forms of cricket range from traditional Test matches played over five days to the newer Twenty20 format (also known as T20), in which each team bats for a single innings of 20 overs (each "over" being a set of 6 fair opportunities for the batting team to score) and the game generally lasts three to four hours.

In cricket, an extra (sometimes called a sundry) is a run scored by, or awarded to, a batting team which is not credited to any individual batter. They are the runs scored by methods other than striking the ball with the bat.

The extras are tallied separately on the scorecard and count only towards the team's score. Giving away many extras is often considered as untidy bowling.

Run out is a method of dismissal in cricket, in which the fielding team put down the wicket of a batter who is outside their ground, usually because they are trying to score a run.

Run out is governed by Law 38 of the laws of cricket. If the batter is judged run out, the run does not count and the bowler does not get credit for the wicket.

Test cricket is a format of the sport of cricket, considered the game's most prestigious and traditional form. Often referred to as the "ultimate test" of a cricketer's skill, endurance and temperament, it is a first-class format of international cricket where two teams in whites, each representing their country, compete over a match that can last up to five days. It consists of up to four innings (up to two per team), with a minimum of ninety overs scheduled to be bowled in six hours per day, making it the sport with the longest playing time except for some multi-stage cycling races. A team wins the match by outscoring the opposition with the bat and bowling them out with the ball. Otherwise the match ends in a draw.

It is contested by 12 teams which are the full-members of the International Cricket Council (ICC). The term "test match" was originally coined in 1861–62 but in a different context—that the English team was testing itself against all of the Australian colonies. Test cricket did not become an officially recognised format until the 1890s, but many international matches since 1877 have been retrospectively awarded Test status. The first such match took place at the Melbourne Cricket Ground (MCG) in March 1877 between teams which were then known as a Combined Australian XI and James Lillywhite's XI, the latter a team of visiting English professionals. Matches between Australia and England were first called "test matches" in 1892. The first definitive list of retrospective Tests was written by South Australian journalist Clarence P. Moody two years later and, by the end of the century, had gained acceptance.

In cricket, an over consists of six legal deliveries bowled from one end of a cricket pitch to the player batting at the other end, almost always by a single bowler.

A maiden over is an over in which no runs are scored that count against the bowler (so leg byes and byes may be scored as they are not counted against the bowler). A wicket maiden is a maiden over in which a wicket is also taken. Similarly, double and triple wicket maidens are when two and three wickets are taken in a maiden over.

A delivery or ball in cricket is the single action of bowling a cricket ball toward the batter. Once the ball has been delivered, batters may attempt to score runs, with the bowler and other fielders attempting to stop this by getting the batters out. When the ball becomes dead, the next delivery can begin.

During the play of the game, a member of the fielding team is designated as the bowler and bowls deliveries toward the batter. Six legal balls in a row constitutes an over, after which a different member of the fielding side takes over the role of bowler for the next over. The bowler delivers the ball from their end of the pitch toward the batter standing at the opposite wicket at the other end of the pitch. Bowlers can be either left-handed or right-handed. This approach to their delivery, in addition to their decision of bowling around the wicket (from the sides of the wicket on the bowler's end) or over the wicket, is knowledge of which the umpire and the batter are to be made aware.

Spin bowling is a bowling technique in cricket, in which the ball is delivered relatively slowly but with rapid rotation, giving it the potential to deviate sharply after bouncing. A bowler who uses this technique is called a spinner, a spin bowler, or a slow bowler.

It is one of the two main approaches to bowling, the other being fast bowling.

Sir John Berry Hobbs (16 December 1882 – 21 December 1963) was an English professional cricketer who played for Surrey from 1905 to 1934 and for England in 61 Test matches between 1908 and 1930. Known as "The Master", he is widely regarded as one of the greatest batsmen in the history of cricket. He is the leading run-scorer and century-maker in first-class cricket, with 61,760 runs and 199 centuries. A right-handed batsman and an occasional right-arm medium pace bowler, Hobbs also excelled as a fielder, particularly in the position of cover point. Hobbs was named as one of the five Wisden Cricketers of the Century alongside Sir Donald Bradman, Sir Garfield Sobers, Shane Warne, and Sir Viv Richards.

Born the eldest of 12 children to a Cambridge cricket groundsman and umpire in 1882, Hobbs wished from an early age to pursue a career in cricket from following his father's matches at Cambridge University colleges, and playing for teams on Parker's Piece.
