Prior ready for explosive display

Prior is Sussex's leading one-day run-scorer

Matt Prior hopes his ability to perform under pressure will help him in a brand new role for England against Australia.

Prior is likely to be England's first tactical substitute after being added to the one-day NatWest Challenge squad.

"Since finding out, a million things have gone through my mind, like what the situation might be and how I will have to adapt," Prior said.

"The role means you will have to adapt and hopefully I will show I am the type of player that can."

Under the new regulations, approved by the International Cricket Council a fortnight ago, a player may be replaced by the nominated 12th man at any time in the match.

Fielding restrictions which used to be in force for the first 15 overs of each innings could now come into play at any time, favouring explosive batting and attacking bowling.

Thursday's match at Headingley will mark the start of a 10-month trial of the rules.

Prior, who is unlikely to unseat current keeper Geraint Jones, is the leading run-scorer in the domestic Totesport League Division Two, with 399 runs in seven matches.

He made his one-day international debut on last winter's trip to Zimbabwe, scoring 35 in the final match of a 4-0 series victory.

"Performing under pressure is the biggest thing and I enjoy it, that is something I have proved with Sussex and England A," Prior added.

"It is a 'no fear' thing and I intend to thrive on this. I am not going to be scared of trying things if the chance comes.

"I have found my own way of playing; I don't envisage walking down the wicket to try to hit Brett Lee over cover but I like to set a tempo if I can."
