The Laws state that, throughout an innings, "the ball shall be bowled from each end alternately in overs of 6 balls". The name "over" came about because the umpire calls "Over!" when six balls have been bowled. At this point, another bowler is deployed at the other end, and the fielding side changes ends while the batsmen do not. A bowler cannot bowl two successive overs, although a bowler can (and usually does) bowl alternate overs, from the same end, for several overs which are termed a "spell". The batsmen do not change ends at the end of the over, and so the one who was non-striker is now the striker and vice-versa. The umpires also change positions so that the one who was at "square leg" now stands behind the wicket at the non-striker's end and vice-versa.
The most famous player of the 19th century was W. G. Grace, who started his long and influential career in 1865. It was especially during the career of Grace that the distinction between amateurs and professionals became blurred by the existence of players like him who were nominally amateur but, in terms of their financial gain, de facto professional. Grace himself was said to have been paid more money for playing cricket than any professional.
Since 2000, the Indian team underwent major improvements under the captaincy of Sourav Ganguly and guidance of John Wright, India's first ever foreign coach. India maintained their unbeaten home record against Australia in Test series after defeating them in 2001. The series was famous for the Kolkata Test match, in which India became only the third team in the history of Test cricket to win a Test match after following on. Australian captain Steve Waugh labelled India as the "Final Frontier" as a result of his side's inability to win a Test series in India. Victory in 2001 against the Australians marked the beginning of a dream run for India under their captain Ganguly, winning Test matches in Zimbabwe, Sri Lanka, West Indies and England. The England series is also known for India's highest ODI run-chase of 325 runs at Lord's which came in the Natwest ODI Series final against England. In the same year, India were joint-winners of the ICC Champions Trophy with Sri Lanka and then went to the 2003 Cricket World Cup in South Africa where they reached the final, only to be beaten by Australia. The 2003–04 season also saw India play out a Test series in Australia where they drew 1–1 with the world champions, and then win a Test and ODI series in Pakistan.
