2015 saw the beginning of India's dominance at home in Test matches under new captain Virat Kohli when they comprehensively beat South Africa. This series was the beginning of an unbeaten streak of 19 Test matches for India which was brought to an end by Australia in early 2017. This series also saw the emergence of Ravichandran Ashwin and Ravindra Jadeja as two of the best spinners and all-rounders. They spun webs around touring batsmen, much like the spinning quartet of the 1970s. This was followed by limited overs victories over Australia and Sri Lanka away from home. India was knocked out of the 2015 World Cup in the semi-final stage, to eventual winners Australia. India began 2016 by winning the 2016 Asia Cup, remaining unbeaten throughout the tournament, beating Pakistan along the way. India were favourites to win the 2016 ICC World Twenty20 which was being held at home, but they lost in the semi-final to eventual champions West Indies. Virat Kohli was again named the man of the series.
The ball is a hard leather-seamed spheroid, with a circumference of 22.9 centimetres (9.0 in). The ball has a "seam": six rows of stitches attaching the leather shell of the ball to the string and cork interior. The seam on a new ball is prominent and helps the bowler propel it in a less predictable manner. During matches, the quality of the ball deteriorates to a point where it is no longer usable; during the course of this deterioration, its behaviour in flight will change and can influence the outcome of the match. Players will, therefore, attempt to modify the ball's behaviour by modifying its physical properties. Polishing the ball and wetting it with sweat or saliva is legal, even when the polishing is deliberately done on one side only to increase the ball's swing through the air, but the acts of rubbing other substances into the ball, scratching the surface or picking at the seam are illegal ball tampering.
It is generally believed that cricket originated as a children's game in the south-eastern counties of England, sometime during the medieval period. Although there are claims for prior dates, the earliest definite reference to cricket being played comes from evidence given at a court case in Guildford on Monday, 17 January 1597 (Julian calendar; equating to 30 January 1598 in the Gregorian calendar). The case concerned ownership of a certain plot of land and the court heard the testimony of a 59-year-old coroner, John Derrick, who gave witness that:
During the 1980s, India developed a more attack-minded batting line-up with stroke makers such as the wristy Mohammed Azharuddin, Dilip Vengsarkar and all-rounders Kapil Dev and Ravi Shastri. India won the Cricket World Cup in 1983, defeating the favourites and the two-time defending champions West Indies in the final at Lords, owing to a strong bowling performance. In spite of this, the team performed poorly in the Test arena, including 28 consecutive Test matches without a victory. In 1984, India won the Asia Cup and in 1985, won the World Championship of Cricket in Australia. Apart from this, India remained a weak team outside the Indian subcontinent. India's Test series victory in 1986 against England remained the last Test series win by India outside the subcontinent for the next 19 years. The 1980s saw Gavaskar and Kapil Dev (India's best all-rounder to date) at the pinnacle of their careers. Gavaskar made a Test record 34 centuries as he became the first man to reach the 10,000 run mark. Kapil Dev later became the highest wicket-taker in Test cricket with 434 wickets. The period was also marked by an unstable leadership, with Gavaskar and Kapil exchanging the captaincy several times.
Since international teams started using different kits for T20s and ODIs, Nike released the first T20 kit for the team in 2016 with a similar shade and a contemporary design. Multiple thin strips of orange and green were included on upper right and lower left sides of the jersey respectively. A new ODI jersey was unveiled by Nike in 2017 with a similar shade of blue for the body and a darker shade of blue for the sleeves. The tricolour accent made a return to the uniform as a single thin strip on either sides of upper chest.
Historically, cricket's origins are uncertain and the earliest definite reference is in south-east England in the middle of the 16th century. It spread globally with the expansion of the British Empire, leading to the first international matches in the second half of the 19th century. The game's governing body is the International Cricket Council (ICC), which has over 100 members, twelve of which are full members who play Test matches. The game's rules are held in a code called the Laws of Cricket which is owned and maintained by Marylebone Cricket Club (MCC) in London. The sport is followed primarily in the Indian subcontinent, Australasia, the United Kingdom, southern Africa and the West Indies, its globalisation occurring during the expansion of the British Empire and remaining popular into the 21st century. Women's cricket, which is organised and played separately, has also achieved international standard. The most successful side playing international cricket is Australia, which has won seven One Day International trophies, including five World Cups, more than any other country and has been the top-rated Test side more than any other country.
India has had six regular Test captains since Mohammad Azharuddin took charge in 1989. Azharuddin led the team in 47 Test matches from 1989–90 to 1998–99, winning 14, and in 174 ODIs, winning 90. He was followed by Sachin Tendulkar, who captained the team in 25 Test matches and 73 ODIs in the late 1990s; Tendulkar was relatively unsuccessful as a captain, winning only 4 Test matches and 23 ODIs. He was replaced as ODI captain by Ajay Jadeja and then by Sourav Ganguly.
Since 2000, the Indian team underwent major improvements with the appointment of John Wright, India's first ever foreign coach. This appointment met success internationally as India maintained their unbeaten home record against Australia in Test series after defeating them in 2001 and won the inaugural ICC World T20 in 2007. India was also the first Sub-continental team to win at the WACA in January 2008 against Australia.
A match's statistics are summarised on a scorecard. Prior to the popularisation of scorecards, most scoring was done by men sitting on vantage points cuttings notches on tally sticks and runs were originally called notches. According to Rowland Bowen, the earliest known scorecard templates were introduced in 1776 by T. Pratt of Sevenoaks and soon came into general use. It is believed that scorecards were printed and sold at Lord's for the first time in 1846.
