In 2016, "The Grand Home Season" began for India, including series at home against New Zealand, England, Bangladesh and Australia. India whitewashed New Zealand to regain the number one ranking in Test cricket after almost 10 years. Before the series against England in November 2016, MS Dhoni resigned as captain of India in limited overs, thus handing the captaincy to Virat Kohli across all formats. India beat England across all three formats, with a notable 4–0 win in the Test series. This was followed by Test series wins against Bangladesh and Australia, which meant India reclaimed the Border Gavaskar Trophy. Ravichandran Ashwin became the fastest cricketer of all time to reach 250 wickets; he and Ravindra Jadeja occupied the top two spots in both the ICC Bowlers and All-Rounders rankings at the time. In the process, India became the third team (after South Africa and Australia) to have won their most recent Test series against all the other Test-playing nations. India holds an unbeaten streak of 8 consecutive Test series wins as of 19 August 2017.
Most bowlers are considered specialists in that they are selected for the team because of their skill as a bowler, although some are all-rounders and even specialist batsmen bowl occasionally. The specialists bowl several times during an innings but may not bowl two overs consecutively. If the captain wants a bowler to "change ends", another bowler must temporarily fill in so that the change is not immediate.
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.
In December 2006, India played and won its first ever Twenty20 international in South Africa, becoming the most recent Test team to play Twenty20 cricket. The beginning of 2007 had seen a revival in the Indian team's ODI fortunes before the 2007 Cricket World Cup. Series victories against the West Indies and Sri Lanka, marked by the comeback of Ganguly, and strong form by Tendulkar, and the emergence of young players like Robin Uthappa saw many pundits to tip India as a real contender to win the 2007 Cricket World Cup. However, defeats to Bangladesh and Sri Lanka saw India fail to reach the second round.
