If Joe Root would've been out there, I would've just said Australia's not for you, Joe.

Scott Boland did get something on it! Fortunately, Joe Root is in the zone and stretches to get his bat down before the ball hits the stumps.

Oh ummm... has Joe Root been run out at the non-striker's end?

Ollie Pope was driving back down the ground. Did Scott Boland get something on it?

Oooooohs all round as Joe Root plays and misses at a fuller delivery. Less of that, Joe.

Mitchell Starc has 2-10 from his opening four overs.

Starc is the man this morning.

Joe Root will be remembered as a great player, he's already played over 180 Test matches, the stats in themselves are quite incredible.

If he doesn't score a century here in Australia, it will always be a mark held against him.

Mitchell Starc has found his rhythm, he's just gliding down and releasing the ball.

Here comes the big moment of the series.

That's really full.

HUGE appeal from Mitchell Starc for lbw and Ben Duckett is given out!

He's sending it upstairs. My finger was up.

Phil Tufnell
Former England spinner on BBC Test Match Special

Full again, that's when you can really look to punish, that was fuller than a half volley. That's when you can afford to play the expansive shots.

I was just about to say that Ben Duckett is looking quite comfortable...

He's lapping up the full deliveries from Scott Boland, driving another for four, but he's not putting his waft away and it's a bit nerve-jangling. Alex Carey goes up enthusiastically for caught behind but Steve Smith ignores him.

Mitchell Starc's first over had an average speed of 146.2kph (90.8mph). That is the quickest first over of an Ashes series in the ball-tracking era.

Ollie Pope drives into the covers for three, the ball grinding to a halt in the outfield.

Ben Duckett flicks behind for four.

Mitchell Starc flashes a couple of deliveries past the edge of Duckett's bat.

A good tussle.

That's the best timed stroke we've seen so far. England can just breathe a little now.

That will settle a few jitters! Ben Duckett guides Scott Boland through mid-on and away for four - the first boundary of the series.

Two balls later, he shoulders arms. That's two leaves inside four overs from the opener.

Never fear, he's back to his usual self for the final ball of the over, this time driving through mid-off for four.

All of England's runs have come off Boland's bowling.

Mitchell Starc, bowling in the mid to high-80s in this opening burst, has started with back-to-back maidens.

That's the third best start in an Ashes series that England have had in Australia the past five tours.
