Not willing to blame the batsmen for India's sudden collapse, vice-captain Virender Sehwag [Images] said all of them fell to good deliveries though the wicket was playing well.

"(Sachin) Tendulkar, Rahul (Dravid), Sourav (Ganguly) all fell to good balls, so you cannot do anything about it. They (Sri Lanka [Images]) have quality bowlers," Sehwag said, after the first day's play in the second Test against Sri Lanka, in which India lost its top four batsmen in the space of 10 runs.

But the opener, who was unbeaten on 128 at close, said, "I think 350 to 400 runs should be a good total on this wicket."

On his secret of clobbering Ajantha Mendis [Images], Sehwag said he picked the mystery bowler rather early.

Asked what he felt about Dravid's dismissal, as it appeared that the ball had hit the fielder's helmet before it was held, Sehwag said he could not pick it.

"I don't know, because I was at the non-strikers end and could not pick it up. I was in doubt whether the ball had hit or hot. But I felt it had hit (the helmet). I feel if they (Sri Lankans) had known about it, then it was not the right spirit of the Sri Lankans. If the Sri lankans had known it then (I think) they should have played with the right spirit and said that the ball had hit the helmet."

Television replays showed that the ball popped off the short-leg fielder, hit his right shoulder and came off the helmet grill before he caught it.

"We were in a good position. The first-wicket partnership was around 167 runs and then we lost four wickets. These things happen in a Test match. It happens so many times but you cannot do anything," Sehwag said.

Asked whether Gambhir was out, as the review took a long time, Sehwag said earlier he thought the ball could have missed the stumps, but replays showed otherwise.

"I thought it was a googly and then it could have been on the off-stump also because sometimes it becomes difficult for the umpires to pick. But then it struck on the middle stump. We just took a chance to avail of the review system," he said.

Sehwag said the loss of four hours of play did not have any bearing on him.

"There was no impact on my batting after delay of four hours. But every batsmen plays with a different mindset. Maybe some other batsmen could have been affected by it. But I was just playing my shots."
