Mumbai: Sri Lankan openers survive the three overs before the Close of Play on day 3. But the day belonged to India completely.
Though, it was a disappointment to see Sehwag missing his third triple ton, the crowd would have been happy to see Dhoni score a fabulous hundred and help India extend their lead 333-runs.
It's an uphill task from now on for Lanka to save this Test as India looks the only team to win the game from now on. The visitors still trail by a major margin of 322 runs with two days left.
Virender Sehwag fell just short of becoming the first ever batsman to score three Test triple centuries on Friday, but the hosts declared 726-9 just before stumps on day three of the third and final Test against Sri Lanka.
Sehwag was dismissed for 293, adding nine runs to his overnight score before offering a return catch to off spinner Muttiah Muralitharan, who fumbled the attempt before holding the ball.
Sehwag's overnight partner Rahul Dravid (74) soon followed him to the pavilion before VVS Laxman (62) and Sachin Tendulkar (53) posted half-centuries to help India build its lead over Sri Lanka's first innings total of 393.
Sehwag's two triple centuries were against Pakistan at Multan in 2004 and South Africa at Chennai in 2008.
Brian Lara of the West Indies and Australian Donald Bradman are the only other cricketers in Test history to have passed 300 runs on two different occasions.
Sehwag struck seven sixes and 40 boundaries from 254 deliveries to dominate the Sri Lankan bowlers.
The expectation of Sehwag making another triple century drew a large crowd to the Brabourne Stadium, but the spectators were yet to settle in when Sehwag mistimed a drive to give Muralitharan his first wicket of the match.
Dravid struck a six and five boundaries from 147 balls before nicking Chanaka Welegedara's delivery to wicketkeeper Prasanna Jayawardene.
India lead the three match series 1-0 in after winning the second Test by an innings and 144 runs.
