Colombo, Aug 27 (IANS) Australian all-rounder Shane Watson has revealed that he consulted Indian batting star Rahul Dravid on how to convert good starts into big scores and overcome concentration lapses during an innings.

Watson, who is the vice-captain of the Test squad touring Sri Lanka, said he has a burning ambition to make big hundreds in Test cricket. He currently averages 50.33 in 27 Tests with the highest of 126.

"To get bigger scores is a burning ambition for me. It is something that I really want to be able to get right before the end of my career and being able to capitalise on the good days," Watson was quoted as saying by Sydney Morning Herald Saturday.

"I have talked to different people about it because there is no doubt that I need to learn and get better at it. In the end, it really just comes down to my concentration and being able to block out anything that is going around. It is about getting back to what is the most important thing for all batsmen, which is watching the ball."

Watson said he sought Dravid's advice during the fourth edition of the Indian Premier League where they both played for the Rajasthan Royals.

"I have talked to Ricky (Ponting) on how to focus more. During the IPL I talked to Rahul Dravid. He was at Rajasthan with me. I had a few really good chats with him about what he goes through to be able to bat for a long period of time.

"I have got to be mentally tougher to make sure I do get through those periods where your concentration starts to lapse," he said.
