An inning, or innings, is a fixed-length segment of a game in any of a variety of sports – most notably cricket and baseball during which one team attempts to score while the other team attempts to prevent the first from scoring. In cricket, the term innings is both singular and plural and is always spelled and pronounced with the terminal "s". In baseball and softball, the singular form is inning and only the plural takes an "s".

In many other sports, the length of the game is dictated by a clock and teams swap offensive and defensive roles dynamically by taking possession of a ball or similar item. In baseball and cricket, however, one team, said to be "batting", attempts to score "runs"—see run (baseball) and run (cricket)—while the other team, said to be "fielding", attempts to prevent the scoring of runs and get members of the batting team out. The teams switch places after the fielding team has succeeded in getting a fixed number of players out, making a clock unnecessary.

In cricket, the term innings is also used to refer to the play of one particular player (Smith had a poor innings, scoring only 12). By extension, this term can be used in British English for almost any activity which takes a period of time (The Liberal government had a good innings, but finally lost office in 1972, or You've had a fair innings, now it's my turn, meaning "you have spoken for long enough, now let me speak"). It is also used in reference to someone who has died at a reasonably old age or lived a rich and rewarding life (Ah, well. John was 89. At least he had a good innings). The baseball-derived parallel to this in American English is the term at bat.

Sachin Ramesh Tendulkar ( pronunciation (help·info); born 24 April 1973) is an Indian cricketer widely considered to be one of the greatest batsmen of all time. He is the leading run-scorer and century maker in Test and one-day international cricket. He is the first player to score a double century in ODI cricket. In 2002, just 12 years into his career, Wisden ranked him the second greatest Test batsman of all time, behind Donald Bradman, and the second greatest one-day-international (ODI) batsman of all time, behind Viv Richards. Tendulkar was a part of the 2011 Cricket World Cup winning Indian team in the later part of his career, his first such win in six World Cup appearances for India. He is currently nominated for receiving the Bharat Ratna award.

Sahibzada Mohammad Shahid Khan Afridi (Urdu: صاحبزادہ محمد شاہد خان آفریدی) (born 1 March 1980 in Khyber Agency of the Federally Administered Tribal Areas, Pakistan), popularly known as Shahid Afridi (Pashto: شاهد ‏افریدی), is a Pakistani cricketer. Between 1996 and 2012, Afridi played 27 Tests, 334 One Day Internationals, and 46 Twenty20 Internationals (T20Is) for the Pakistani national team. He made his ODI debut on 2 October 1996 against Kenya and his Test debut on 22 October 1998 against Australia.

He is known for his aggressive batting style, and holds the record for the fastest ODI century which he made in his first international innings, as well as scoring 32 runs in a single over, the second highest scoring over ever in an ODI. He also holds the distinction of having hit the most number of sixes in the history of ODI cricket. Afridi considers himself a better bowler than batsman, and has taken 48 Test wickets and over 300 in ODIs. Currently Afridi is the leading wicket taker in the Twenty20 format taking 53 wickets from 43 matches.

Sourav Chandidas Ganguly ( pronunciation (help·info); born 8 July 1972) is a former Indian cricketer, and captain of the Indian national team. Born into an affluent family, Ganguly was introduced into the world of cricket by his elder brother Snehasish. He is regarded as one of India's most successful captains in modern times. He started his career by playing in state and school teams. Currently, he is the 5th highest run scorer in One Day Internationals (ODIs) and was the 3rd person in history to cross the 10,000 run landmark, after Sachin Tendulkar and Inzamam Ul Haq. Wisden ranked him the sixth greatest one day international batsman of all time, next to Viv Richards, Sachin Tendulkar, Brian Lara, Dean Jones and Michael Bevan.

After a series of playing in different Indian domestic tournaments such as the Ranji and Duleep trophies, Ganguly got his big-break while playing for India on their tour of England. He scored 131 runs and cemented his place in the Indian team. Ganguly's place in the team was assured after successful performances in series against Sri Lanka, Pakistan and Australia, winning the Man of the Match awards. In the 1999 Cricket World Cup, he was involved in a partnership of 318 runs with Rahul Dravid, which remains the highest overall partnership score in the World Cup tournament history.

Brian Charles Lara, TC, OCC, AM (born 2 May 1969, in Santa Cruz, Trinidad and Tobago) is a former West Indian international cricket player. Lara is generally regarded as one of the greatest batsmen of all time. He topped the Test batting rankings on several occasions and holds several cricketing records, including the record for the highest individual score in first-class cricket, with 501 not out for Warwickshire against Durham at Edgbaston in 1994, which is the only quintuple hundred in first-class cricket history. The BBC radio commentary on the final day of the innings (6 June 1994), by Dave Roberts, was being broadcast around the world live via the BBC World Service network, and in the UK on BBC Radios 1, 2 & 4 as well as the majority of BBC Local radio stations. That evening, as Lara neared the all-time batting record, a huge surge of fans crowded to enter the grounds.

Lara also holds the record for the highest individual score in a test innings after scoring 400 not out against England at Antigua in 2004. He is the only batsman to have ever scored a hundred, a double century, a triple century, a quadruple century and a quintuple century in first class games over the course of a senior career. Lara also holds the test record of scoring most number of runs in a single over in a Test match, when he scored 28 runs off an over by Robin Peterson of South Africa in 2003.
