India completed a crushing victory over Australia by a record margin of 320 runs in the second Test in Mohali on Tuesday to seize a 1-0 lead in the four-match series.
Left-arm paceman Zaheer Khan grabbed three wickets in four balls on the final day as Australia, chasing an improbable victory target of 516 runs, were dismissed for 195 before lunch.
It was India's biggest ever Test win by runs, bettering their 280-run success over South Africa in Kanpur in 1996-97.
