It was the day England's World Cup campaign was put firmly back on track after the nerves and niggles of Trent Bridge.
And, perhaps even more significantly, it was the day England discovered beyond question their new opening batsman and bowler for the Ashes.

Ed Smith made the call to bring Jos Buttler back to Test cricket last summer even though he had barely played in the first-class game and now Roy, with five scores of 50 or more in his last six one-day internationals, looks certain to follow the same path.
In truth it has been a long time coming. Paul Farbrace, the assistant coach who did so much to get England where they are today in the white-ball game before leaving for Warwickshire, has long thought of Roy as a potential Test batsman and told the BBC in
