Virat Kohli smashed his fourth century of the series on day three of the fourth Test against Australia at the Sydney Cricket Ground and thus became the first test captain in cricket history to score three centuries in first three innings. Australian Greg Chappell had scored a century each in his first two innings as skipper against the West Indies at Brisbane in 1975. Kohli also surpassed the earlier record of batting legend Rahul Dravid who scored 619 runs from eight innings in the 2003-04 tour of Australia. Kohli, who came into this match with an aggregate of 499 runs, has now totalled 639 from seven innings. He is also the second Indian after Sunil Gavaskar to register four tons in a Test series. The former Indian captain did it twice against the West Indies in 1971 and 1978-79.
