It was nice to score a century after getting out for 63 in the first innings Tillakaratne Dilshan

The tourists, who batted out the final day in Galle, begin day five in Kandy 89-2, needing an improbable 368 to win.

"It's going to be a very tough day [on Sunday], but I think the boys must take heart out of the way they salvaged a draw in the first Test," said Fletcher.

"They should be able to do the same, if not better."

Fletcher praised Tillakaratne Dilshan, who became the first centurion in the series as the home side recovered from the loss of two early wickets to declare on 279-7.

"Dilshan batted very well and took the game away from us," the coach told BBC Sport.

"He was very positive and it was a very hard struggle on this wicket."

Dilshan himself was pleased to reach three figures after falling short - although he was top-scorer - in the first innings.

"I was asked to go for my strokes and that's the way I like playing," he said.

"It was nice to score a century after getting out for 63 in the first innings.

"I thought I could've got a hundred in the first knock, but am glad to get a chance of making up for the disappointment this time."

England captain Michael Vaughan, 52 not out overnight, will have to follow Dilshan into three figures if his side are to get through the last day, but Fletcher is confident.

"Michael Vaughan batted really well for another good 50 and it's pleasing to see him get two good scores under his belt," he added.

"Hopefully tomorrow he can go through and get one of those big scores he's known to get.

"Your powers of concentration have got to be enormous. With Muralitharan bowling from one end and the ball turning all the time you never really feel in."

Bad light ended play 12 overs early on Saturday and thunderstorms are forecast for Sunday but Fletcher emphasised his team must "control the controllables".

"If it rains it rains but we've got to be prepared if it doesn't rain," he went on.

"The batters go all the way to number 10 but we have to make sure the guys take on the responsibility.

"Each guy has got to make sure that he is going to win the game and not leave it to someone else."
