England reach 319-7 against Australia on the first day's play of the decisive Ashes Test at The Oval.

Warne gets the vote because he put Australia just on top

Although Andrew Strauss batted for most of the day for an excellent century, Shane Warne's outstanding contribution with the ball has given his team the edge.

He was brought on to bowl in the first hour of the day as England's openers got the innings away to a flying start.

He swiftly broke the partnership between Marcus Trescothick and Andrew Strauss when Matthew Hayden took an excellent low catch at slip.

Michael Vaughan followed when he casually clipped to mid-wicket and when, in Warne's next over, Ian Bell was lbw for a duck, the Test had very much swung back Australia's way.

Warne continues to surprise us.

Having not bowled a single googly in the series to date, he produced at least three today.

While they were not particularly accurate, they showed that his injury prone right shoulder is still capable of producing his variations when they are really needed.

England would have hoped that winning the toss would have been the sealing factor.

Ponting lost the toss and England thought they were on their way

Their plan would have been to bat all day, and tomorrow too, and post a first-innings total of 500.

Instead, the dismissal of Strauss - to give Warne his 31st five-wicket haul - really sealed the day for Australia.

It was an excellent diving catch by Simon Katich at silly point that brought about Strauss's downfall for 129, and it meant that Australia were through to the lower order.

The selection of Paul Collingwood ahead of James Anderson will be widely debated.

And the fact that Collingwood scored only seven runs will inevitably lead to criticism of the decision.

In fact, Collingwood was unlucky to be given out lbw by Rudi Koertzen because his foot was outside the line of off-stump when the ball struck him on the toe.

This could well prove to be the pivotal day of the series - the day on which the destiny of the Ashes is decided.

Australia will be looking to dismiss England as quickly as possible, and then take control of the match by setting the foundation for a large first-innings lead.
