Jon Matthews: Pollution stops play at Delhi. Good idea: let's get every English person in Australia driving around and around the ground until the umpires stop play.

Starc tempts Cook into a waft outside off stump, that away swing again pushing the ball away from Cook's bat. That's nice from Cook, shovelling off his pads and away for three. Australia have been right on the money so far. They've found that fuller length that eluded England for near enough 100 overs. Stoneman gets a couple as the ball bounces awkwardly in front of Pat Cummins at mid-on, and his attempted grab misses.

If you're at the back of the top tier, you're miles away, but square of the wicket at ground level is right in the game. The members are practically fielding at point. Nice rainbow, too.

Josh Hazlewood, the slips, half the ground and probably some catering staff go up as Hazlewood raps Stoneman on the pad, but Aleem Dar shakes his head. That had pitched well outside leg. Stoneman ignores the next two before jabbing his bat down on a good yorker. In fact, that's cracked his bat. Stoneman wafts his arm around and it takes Gary Ballance ages to realise that he's talking to him. That bat currently resembles a horse's hoof. Another big lbw appeal rounds off the over but again, that pitched outside leg.

Just been asked by an Aussie how many wickets England would lose tonight. I said worse case scenario three or four. "First or second innings" he replied.

Close! Oh, that was in the air! It's a leading edge from Mark Stoneman as he gets squared up by Mitch Starc, and the ball flies past Usman Khawaja at gully and away for four. That went with such speed that Khawaja would have needed wings to get hold of that. Stoneman has another little fiddle at a Starc delivery, and again! There's away swing from Starc, and Stoneman, plonked on the back foot just pushes loosely at it. Starc's set him up for the fuller delivery, which he taps away for a single, before Cook hooks the ball down onto the ground.

There's a short leg in place for Mark Stoneman, who promptly drives a slightly wider delivery away for a single. There's some swing for Hazlewood, as Cook plays rather awkwardly off his pads, before the next delivery goes zipping past Stoneman. It's Shaun Marsh in at short leg! What a way to celebrate making an Ashes century - go get the lid on and stand under the batsman's nose. A nice drive from Stoneman brings about a few more runs, before Cook has a poke at the final ball of the over. Not a lot of foot movement from Cook there.

The last ball of that Starc over was 93mph. Easily the fastest thing we've seen all match.

It'll be Josh Hazlewood at the other end.

England have got to leave well and know where the off stump is. One wicket down is the maximum for England.

Runs! Starc drifts on to Cook's pads and he turns the ball off his hips for a single. And that's good work from Stoneman, dropping his first delivery away and darting through for a quick single, much as Australia did. That's a better length from Starc, in that off stump channel, and Cook, hanging back, considers a nibble at it. One over down, 27 more to go.

Mitch Starc has the ball in hand. In he comes, knees pumping, and sends down a 90mph delivery that Cook leaves alone. It goes through to Tim Paine at shoulder height.

Cook did score 243 in England's last day-night Test. Admittedly, it was at Edgbaston, against a West Indies side who gifted him at least half of those. But, you know. Positive signs.

Here the England openers come. Nathan Lyon tries to engage Cook in a bit of chat as he walks to the crease. Cook ignores him.

David Laurie: Well at least Cook is in decent nick.

It's been said a lot, Jack, but it's not until you see this England attack away from home that you realise how samey it is. And that goes for the first Test, too. There were times when you couldn't tell if it was Jake Ball or Chris Woakes bowling.

Still, three wickets on debut for Craig Overton. They've come at a cost of 105 runs.

England will have 28 overs to see out tonight. 28 overs of Hazlewood, Cummins and Starc with some Lyon on a pitch that has been offering turn and bounce. I'd be sitting on a chair in the dressing room and refusing to move.

I've just done a bit of maths. James Anderson and Stuart Broad have already bowled a combined 136 overs in this series, in three innings. Not idea, is it?

When the wheels come off in Australia they really do come off quite spectacularly.

Shaun Marsh's selection was derided at the start of this series, and yet he's impressed in both his innings of this series. He looked superb today. And the hitting just then made sure that England's shoulders would droop that bit further.
