Jacob Bethell is just the second England men's batter to register three fifty plus scores in a Test series at the age of 21 or under - the other being Sir Alastair Cook (2 x 100s, 1x 50 vs Pakistan, 2006).

The TV coverage has just shown Will O'Rourke's speeds from his previous over, with one delivery pushing 93mph.

He continues to give Jacob Bethell a bit of a working over with a short ball that requires evasive action, before a fuller delivery somehow evades the outside edge.

Time for a drinks break after a solid start to the session for England.

Jacob Bethell is hit where you do not want to be hit as Will O'Rourke gets one to jag back in sharply to the left-hander.

He needs a minute to compose himself but is soon ready to go again.

O'Rourke ends a fine over with a beauty that fizzes past Bethell's edge. There is a half-hearted appeal from some of the slips and Tom Latham considers a review, but eventually declines.

Mitchell Santner is bowling over the wicket to Jacob Bethell, looking to land the ball in the foot holes outside his off stump.

There is a brief flurry of excitement as an attempted reverse-sweep loops up towards first slip, but the ball didn't carry.

Time for some spin as Mitchell Santner replaces Tim Southee.

Very little in terms of swing (0.34°) and seam (0.57°) today so it's the variable bounce that England will be wary of.

The PitchViz Bounce Inconsistency rating (higher = more inconsistent) sits at 6.9/10 in this session, only during the opening session of day three in Wellington have we seen a higher rating in this series (5 wickets fell during that session).

Joe Root goes aerial with a pull off Will O'Rourke, but Root knows where the fielders are so the ball lands in space before rolling over the rope.

Root is then cramped for room slightly and gets away with a couple of attempted cuts that come off the inside edge but avoid the stumps.

TV has just done analysis of Joe Root's batting that was played on the big screen inside the ground. Root watched it from the non-striker's end.

A powerful front foot pull brings another four for Jacob Bethell, who has looked in good nick so far.

He is four runs away from a third Test half-century in as many matches.

So you're telling me there's a chance?

I'm sure your fellow BBC Sport website readers can help you out with this one, Andy.

Let us know your suggestions everyone.

Joe Root makes the most of his reprieve with a glorious drive through the cover for four.

He is then squared up by Matt Henry and is fortunate the ball catches the edge and flies downwards, hitting the deck before reaching the slips.
