Chris Rogers and Steve Smith made the most of a flat Lord's pitch to rack up a record-breaking stand and put Australia in complete command of the second Ashes Test at Lord's.

Michael Clarke won the toss and unsurprisingly opted to bat, with Rogers and Smith fully vindicating their skipper's decision by putting on an unbeaten partnership of 259 and steer the tourists to 337-1 at stumps.

Australia are now firmly in control, as they seek to level the series at 1-1 after England eased to victory in Cardiff last week. 

Here is a summary of stats from day one, provided by Opta:

- Chris Rogers and Steve Smith's unbroken second-wicket stand of 259 is the highest for Australia in an Ashes Test at Lord's
