[3][4] In April 2009, Sehwag became the first Indian to be honoured as the Wisden Leading Cricketer in the World for his performance in 2008,[5] subsequently becoming the first player of any nationality to retain the award for 2009.

[7] Sehwag holds multiple records including the highest score made by an Indian in Test cricket (319 against South Africa at M. A. Chidambaram Stadium in Chennai), which was also the fastest triple century in the history of international cricket (reached 300 off only 278 balls) as well as the fastest 250 by any batsman (in 207 balls against Sri Lanka on 3 December 2009 at the Brabourne Stadium in Mumbai).

[10] On 8 December 2011, he hit his maiden double century in ODI cricket, against West Indies, becoming the second batsman after Sachin Tendulkar to reach the landmark.

He attended Arora Vidya School in Delhi, and pestered his parents to let him play cricket, on the basis that he was not academically gifted.

He was selected to the North Zone cricket team for the Duleep Trophy the following 1998–99 season, ending fifth in the total runscoring list.

[28] Sehwag stood fourth in the Duleep Trophy run-scoring list that year, including a 274, the highest score of the competition.

[33] Sehwag was the captain of the Delhi Daredevils in the first two edition of Indian Premier League, before he quit the position to concentrate more on his batting transferring it to Gautam Gambhir.

[37] Sehwag again led the team in the fifth edition of the league, where he made the record of being the only batsman to score five consecutive half centuries in T20s.

Sehwag had his international breakthrough in Sri Lanka in August 2001 when he was promoted to the opening slot for the tri-series also involving New Zealand.

With Saurav Ganguly's injury in the India-England ODI Series in January 2002, Sehwag received another opportunity to open the innings which he seized by scoring 82 from 64 balls in Kanpur in an eight-wicket Indian victory.

[2] After modest returns on the tours of the West Indies and England in early and mid-2002, he scored 271 runs at 90.33 in the 2002 ICC Champions Trophy in Sri Lanka, with two Man of the Match performances.

In late 2002 he scored an unbeaten 114 from 82 balls that included a 196 run partnership with Ganguly to lead India to a nine wicket win over the West Indies in Rajkot.

[48] He was the only batsman to score a century in the 7 match New Zealand ODI Series where he made two centuries—108 in Napier[49] in an Indian defeat and 112 in Auckland[50] in a one-wicket victory.

He scored poorly in the first group match but bounced back to hit a magnificent 114 from 87 deliveries against lowly ranked Bermuda.

[60] Sehwag's scoring rate is extremely quick, at 103.44 runs per 100 balls (it is exceeded only by one current player: Shahid Afridi, who has a much lower average).

[80] In the First Test of the 2004 Border–Gavaskar Trophy in Bangalore, Sehwag was fined for showing "serious dissent" towards umpire Billy Bowden following an LBW dismissal.

[101] During the 2006 West Indies tour, Sehwag narrowly missed out on scoring a century in the opening session of the Second Test in St Lucia, ending with 99 at the interval.

In December 2007, he was recalled for India's tour of Australia after being omitted form the list of probables,[106] amid calls for his return by several commentators, most notably Ian Chappell.

[108] He played a key part in India's victory, making 72 runs at a brisk pace and taking 2 crucial wickets[109] He scored a match-saving 151 in the second innings of the fourth Test in Adelaide.

This was his first century in the second innings of a test match, and was notable in that he rejected his usual, aggressive batting style in favour of a more defensive approach which was the need of the hour.

Sehwag became only the third batsman after Sir Donald Bradman and Brian Lara to score 2 triple centuries in Test Cricket.

[112] In the first test against England in Chennai in December 2008, Sehwag's rapid 83 off just 68 balls,[113] in the last session of the fourth day, set India up for its record run-chase of 4/387, the highest successful target on Indian soil.

[citation needed] Sehwag was often compared to Sachin Tendulkar in his early days due to the similar batting style, build and appearance.

[118] Sehwag's technique is often cited as being particularly unorthodox, often backing away (considered technically incorrect) to free his arms whilst playing his shots, in particular, and to cut or drive spinners inside out.

Sehwag has also been noted for his apparent disregard for the match situation, exhibited by aggressive batting even when his team is in a poor position or after being outmanoeuvred by the bowler in the recent past.

[126] But over the years, his style has changed from "reckless hitting" to that of "controlled aggression", according to an article in the Sydney Morning Herald.

The first and second innings difference of 37 runs is one of the highest and indicates a lack of ability in dealing with more difficult batting conditions as the pitch deteriorates.

"[137] Sehwag married Aarti Ahlawat in April 2004[138] under heavy security cover in a widely publicised wedding hosted by Arun Jaitley,[139] the then Union law minister of India, at his residence.

The school was inaugurated by his mother and it was his father's dream to have an institution where students can study, stay, train and play sports.

[146][147] Sehwag appeared as guest on Indian Idol show on 21 January 2017 and mentioned that 22 students from his school has represented national and state team in various sports in last 2 years.
