Tillekeratne Dilshan, who hit his fifth Test hundred this year, believes Sri Lanka has a chance to win their first Test in India here if they manage a first innings lead of 150 runs.

The 31-year-old completed his second Test hundred as an opener and 10th overall, anchoring the innings with 112 runs on the second day of first Test here in Ahmedabad.

"Mahela and Thilan need to bat out the first session and the ball will start turning towards the end and a lead of around 150 will give us an edge," Dilshan told journalists.

"It’s great to score a hundred in India. It’s not easy out here. I am very pleased with the way I batted. The decision to open batting has helped me. That’s the best decision I have taken in my career. Now, there’s an opportunity for me to bat longer," he added.

He also felt losing two wickets in quick succession to Zaheer Khan allowed India to get back into the game.

"Those two wickets turned out to be crucial. I shouldn’t have probably played that shot. There was nothing much for the bowlers on that track. The main target we have is to bat longer and get closer to 400 and see how it goes from there. We have two good spinners and if we get that lead we can control things."

Earlier, Sri Lanka’s bowlers did well to claim the last four Indian wickets for 41 runs and Dilshan said things went according to plan for the Sri Lankans. "That was the main target we had. To get the last four wickets before they got to 450. It’s a good batting track and they could have gone on to score more than that. I thought we stuck to our plan and Welagedara bowled a superb first spell and got Rahul early and that was the key."
