Change of angle from Kyle Jamieson after drinks, he over the wicket to the left-handed Emilio Gay.

The second ball of the over scoots along the ground but, unlike the Jacob Bethell dismissal, this goes well wide of the off stump.

Yeah, Jacob Bethell didn't have much chance with this one, Mark.

It is the only wicket to fall since lunch.

A single dropped into the covers by Emilio Gay is the only run from the Nathan Smith over - and that's drinks.

Another good hour or so for England and, in particular, their debutant opener.

Joe Root is off the mark with a boundary. Not one of his finest but an outside edge that is quickly to ground and wide of the slips counts all the same.

The former England skipper is then hit on the pad by an in-swinger from Kyle Jamieson, bringing a muted appeal.

That was sliding down leg.

Emilio Gay is the first England opener to score a half-century on Test debut since Keaton Jennings in 2016. Gay is the first England opener to score a half-century on debut in a home Test since Andrew Strauss on this ground in 2004.

Well played young man, a really good knock, composed and unflustered. Just starting to surge through the veins, it looks like he's enjoying himself out there.

Emilio Gay reaches his half-century on Test debut!

It comes in a fine over for the England left-hander, 16 from it in total.

He starts by guiding the ball through backward point for two before throwing his hands at a wide one from Nathan Smith.

I think he wanted to get that a bit squarer but four is the end result.

And again. Much more control this time, opening the face and running the ball along the ground between the slips and gully for four more.

Two clipped through square leg takes him to his fifty from 84 balls before a gorgeous flick through mid-wicket gives Gay a third boundary in the over.

Emilio Gay drives nicely out to the fielder at deep point, just a single but that brings up the 100 for England.

Joe Root takes a couple of steps down the track to Kyle Jamieson as he faces up for the first time but then lets the ball go, wide of off.

Come home from the IPL? Jacob Bethell could have been hitting red balls all day every day since March and still not have kept that out.

That's tough for Jacob Bethell, that's an absolute pea roller. Good luck playing that, it rolled along. It's a poor pitch.

I've been impressed with the way that Emilio Gay's lined up. O'Rourke's been bowling fast, he's troubled Bethell but they haven't got flustered with it. They've read the situation.

Midway through Matt Henry's latest over and Tom Blundell decides it's time to come up to the stumps.

Immediately it makes a difference with an lbw shout against Jacob Bethell, not given, before an outside edge next ball.

Wide of slip and they get back for two.

Kyle Jamieson replaces Will O'Rourke, who can feel a little hard done by not to have better figures than his 1-23 after eight very challenging overs.

There isn't the same pace from Jamieson but his record tells you that he is still a real threat.

Maiden over with Emilio Gay unable to beat the in-field on a couple of occasions.

Emilio Gay gets two after punching the ball through backward point but he had to be sharp to get back for the second.

Having done so he is drawn into playing at a ball wide of off by Matt Henry and is relieved to see slide just past the edge.

A single takes him to 37 and keeps him on strike.

They usually are, Alex. That's why it has been such a surprise to see them drop as many pretty straightforward catches as they have.

Meanwhile, Will O'Rourke is through his eighth over his spell - either side of lunch - and it's a maiden.
