Sean Abbott replaces Mitchell Starc at the Pavilion End.

Ben Duckett is not quite able to punish a short wide one from the Aussie seamer, and the boundary rider is able to cut it off.

A couple of balls later and Marnus Labuschagne spies a run-out chance after Duckett worked the ball off his pads, but he cannot pick it up cleanly and throws his head back in frustration.

Rather more sedately Ben Duckett works it behind square for a single to bring up a 51-ball half-century. Jos Buttler applauds approvingly on the England balcony.

Fantastic shot! Marnus Labuschagne is not really at long-on, he's very square and it's a bit of a free hit for Ben Duckett.

Ben Duckett skips down the track and powerfully whacks Adam Zampa back over his head for six.

A lot of bottom hand in that, but very cleanly struck.

Adam Zampa, sporting shades, is tossing the ball from hand to hand after drinks as the Aussie leg-spinner prepares to bowl for the first time today.

Dan: So having watched this series so far, who’s going to be dropped when Buttler is fit and Root isn’t being rested?

Lord's bathed in sunshine now as the players take drinks.

As a keeper, when it's that sort of an awkward bounce, you don't always have your eyes on the ball and he would have felt that it would have gone straight in basically.

An Australian wicketkeeper being involved in controversy at Lord's, well I never. This was one was born in Yorkshire, as well.

It's all got a bit 2023 here at Lord's with loud boos from the crowd after the replays show that ball clearly bounced before reaching Josh Inglis' gloves.

Those boos turn to cheers as Harry Brook is given not out, overturning the original decision given on the field.

Boos from the crowd as the TV replays appear to show the ball has kissed the turf.

Has Harry Brook been strangled down the leg side by Mitchell Starc?

There seems to be some doubt if it's carried to Josh Inglis.

Here's how Mitchell Marsh removed Will Jacks a few moments ago. The ball is still hooping round at Lord's.

That wasn't really a bad ball at all from Mitchell Marsh. That's a terrific shot from Harry Brook! That really is!

Since Phil Salt's ODI debut in 2021, only four of the 21 full-member batters to have opened the batting as frequently as Salt have a lower average than his 32.65.

Harry Brook continues to show intent as he hurries down the pitch to the first ball of Mitchell Marsh's third over and clinically whips it through mid-wicket with a bit of a flourish.

The stand-in England skipper dispatches Marsh's penultimate delivery to the fence with a velvety push into the leg side.

Thanks, Mike.

Quite tricky to know what a good score is here given the conditions. You'd have thought a slightly shorter game would probably suit England's batting more than Australia, mind.

Starc returns to replace Abbott, and Brook turns his opening delivery around the corner for four.

Duckett takes three firing the ball out to mid-wicket, before Brook fires a meaty shot out to the deep point fielder to close the over - deserved more than the single it got.

A reasonable start for England - here's Timothy Abraham to take you through the rest of their innings.

Time for Tuesday's centurion, here's England's stand-in skipper Harry Brook.

He takes a single, pushing the ball into the off side.
