OptaJason: Ronchi is the 5th member of this @BLACKCAPS XI to hit a 50+ score on Test debut (Williamson, Watling, Southee and McCullum). Settled.

Anurag: A gentle reminder by Ronchi to Poms before the Ashes that you dont mess with an Ozzie even if he has crossed the Tasman Sea!

As if inspired by Ronchi's heroics, Latham comes down the track to Moeen and hits the ball straight at Gary Ballance at short leg, who may have the time to run him out, but the helmeted fielder can't grasp the ball cleanly as Latham dives back into his crease. A maiden for Moeen - his first and last overs have been maidens, giving him curious figures of 5-2-25-0.

"I bet you this is a taste of what we've got to come in the Ashes series, in that the Aussies will try to target Moeen and give Alastair Cook a problem. In fact Ronchi is an Aussie!"

Ronchi was born in Dannevirke, New Zealand but spent most of his childhood in Australia and played four ODIs and three T20 internationals for Australia in 2008-09.

It's like there are two different games going on here. At one end, Anderson is keeping it tight and keeping New Zealand under control - and at the other, the sixth-wicket pair are tucking into Moeen Ali like schoolkids let loose in the tuck shop. Anderson even finds a bit of late swing, just one single from the over.

"Ronchi's fifty, off 37 balls, is the second fastest by a Test batsman on debut. The fastest was by his team-mate Tim Southee, who hit a half-century off 29 balls against England in Napier in 2008."

It's also the fastest Test fifty at Headingley.

"What a way to bring up your first Test half-century, in your first Test match."

Ronchi continues his aggressive approach, hitting a low skimmer towards Stuart Broad at mid-off, and is dropped as the tall paceman can't quite get down in time and the ball disappears for four. That takes him to 49 - and the Kiwi-turned-Aussie-turned-Kiwi brings up his half-century, from only 37 balls with a powerful slog sweep for six! A sparkling innings by the 34-year-old debutant.

James: I was mistaken for a certain Phil Tufnell. The lady said I looked a bit like him, along with the fact I was wearing a white polo shirt and having a beer in a bar.

Grace, Berkshire: Our family surname is Bowler. Both my dad and brother play cricket, and I used to play county and uni when I was younger. You can imagine the delight from the crowd when the scorer asks "What's the bowler's name?"

Andrew Clark: I was mistaken for the substitute fielder in 2009 Ashes. Unfortunately, the texts I received from so-called friends congratulating me on this achievement, failed to recognise England's latest replacement's name contained a crucial 'e' at the end (Andrew Clarke not Clark). I was forced to correct their misspellings and question several friendships in the process.

You wouldn't think that Latham was the established Test opener and Ronchi the debutant here. Ronchi is picking up runs with consummate ease, while Latham is left fishing at thin air against Anderson.

"Anderson is bowling in a manner just to try to restore a bit of order. Runs have been flowing so rapidly. He's still getting a bit of away-movement."

Leigh Jones: Re: Steve Warriner (17:23), it feels like that story should end "... and that's how I met my first wife".

James Boswell: Steve Warriner could learn a few tips from Ben Stokes on how to write a good story.

There was a big inside edge onto the pad there - umpire Ravi has had a few decisions overturned in this series, but this time he was spot on. England lose a review.

Big appeal from England as Latham prods forward, the fielders are convinced and they want to use a review...

Luke Ronchi seems to be taking to Test cricket very easily, lashing Moeen Ali over long-on for six, the ball crashing into the advertising which covers the rope (but hitting it on the full, as it were). A firmly swept single takes him to 44 from 32 balls.

"First beer snake of the summer appears, with cheers every time a new part is added. Those signs saying they are prohibited were always likely to be ignored."

Anderson, from the Kirkstall Lane End, is probing outside Latham's off stump, and honours are even as the opener survives but Anderson profits to the tune of a maiden over.

Mark in Ely: Re: Test cricketers with Star Wars names (17:20), on the playing side, Owen Wynne played for South Africa from 1948-50 and shares a name with Luke's uncle. However, one character has featured in every single Test match: Princess Leia's adoptive father, Senator Bail Organa.

"The 50 partnership came off just 55 balls, but was still the slowest of the three 50 partnerships in this innings so far."

Ronchi and Latham work the singles against Moeen, while left-hander Latham attempts a sweep but misses the ball which sails down the leg side for four byes - the first byes of the game. Moeen's radar is off as he spins one down the leg side which the right-handed Ronchi helps away for four - that's the fifty stand, from only 55 deliveries.
