Read and Trescothick got England over the line Match report Photos from Lord's

Opener Trescothick scored an unbeaten century as England beat Pakistan by four wickets to win the NatWest Challenge 2-1.

But in a see-sawing match, England looked set to throw away a winning position when they stumbled from 129-2 to 154-6.

"I knew if we could get just one partnership towards the end we'd go close and it would go to the wire," said Trescothick, who was named man of the series.

"We had to graft hard right to the end and I was just keeping check of the score and making sure we were ticking over.

"I was just trying to stay composed and trying to stay focused on what I had to do."

It's been building up for me over the past couple of games and I've been playing pretty well Marcus Trescothick

Trescothick paid tribute to the Chris Read, who belied his inexperience to share in an unbroken stand of 77 that sealed victory for England.

"Chris Read came in and did a great job," he said.

"He's not played too many games and an innings like that was crucial."

After a tough winter in Australia, Trescothick has bounced back to form in a big way.

His century followed a belligerent knock of 86 at The Oval that helped square the series and set up a deciding game.

"It's been building up for me over the past couple of games and I've been playing pretty well," the left-hander added.

Wicket slower

"It's nice to get a hundred and win the game.

"The wicket wasn't quite so good, it was a bit slower and there was a bit of rain around today."

England's first game of the triangular NatWest Series is on Thursday against Zimbabwe at Trent Bridge.

Trescothick's performance over the six matches elevated him to seventh in the one-day international rankings compiled by PricewaterhouseCoopers, a rise of six places.
