BBC Test Match Special statistician

"Kane Williamson has now taken 13 of his 25 Test wickets against England, at an average of 18.69."

Jos Buttler is the new batsman, he drives his first ball to mid-off and New Zealand rush round to get another over in. It's 13:00 by our clock - but obviously still 12:59 by the designated timepiece at Headingley. Are they using the Dickie Bird Clock?

"McCullum does his magic again. He's had a wonderful morning, his bowling changes have always worked. The Kiwis have had a tremendous first session. It's a mistake from Ben Stokes."

Kane Williamson into the attack, replacing fellow off-spinner Mark Craig, and he strikes with his fifth ball. Attempting a flashing cut, Stokes edges to keeper Ronchi, who takes a good catch.

Williamson was suspended from bowling for five months last year for an illegal action, but was cleared to resume in December after remodelling it. But captain McCullum looks to have the Midas touch after that bowling change.

Stef: Think the rain yesterday helped New Zealand. It took the possibility of the run chase away and changed England's mindset to survival only.

Eventually, Stokes resumes, clearly still wincing. He sees off the rest of a maiden over.

Steve Pogson: England were in a similar position on the first morning at Lord's. Can lightning strike twice and England prevail or will it be a Boult from NZ.

"It's horrible when that happens to you. It's worse than being out."

Stokes is literally floored by a delivery which strikes him squarely in the unmentionables. His eyes no doubt watering, he tries to get straight back up, but it's going to take a visit from the physio I think. Umpire Ravi is having a good old giggle, though. Take your time, Ben.

Simon G: Ellis (12:16): you only have to go back to the 2009 Ashes (the Leeds test) where England's three, four and five produced a meagre 16 runs. The common denominator? Ian Bell was involved then too!

Craig, who has bowled unchanged all morning from the Kirkstall Lane End, is back round the wicket to the two left-handers, there are a few oohs and aahs from the close fielders but Cook plays out a maiden.

William Pitt: Once again England are left needing a big innings from experienced batsman Rain. Preferably a not out to get us to the close.

Alex Wright: Why on earth would you hope for rain to avoid losing a Test match? Ridiculous logic. If we're being beaten, so be it!

Stokes gets up on his tiptoes to smack Southee cross-batted for his fifth four, like a baseball player hitting a line drive to left field. Hundred up for the hosts, and this stand is worth 39.

Matt G in Surrey: "The guy at Surrey" Geoffrey is musing about (12:09) is clearly Jason Roy, not KP!

Jason Roy did score 143 and dug his team out of a hole against Lancashire, unlike KP who was out for 2.

"I think England might need a bit of juice from the clouds to help them out. The ball is ripping, and there's only 40 overs until the second new ball. If we get the full overs in, that would give New Zealand 31 overs with the new ball, which is a lot on a pitch like this."

Craig drags one down short and Stokes powerfully whacks it backward of point for four. Five close fielders remain, and there's still plenty of turn for the Auckland-born off-spinner, who was condemned by some after the Lord's Test but has had an excellent match for New Zealand.

David Christian Rose: Boult showing the advantages of a left-arm quick, how about take another serious look at Mark Footitt.

Callum Harvey: James Hildreth needs to be considered for the England middle order. Close to 1,000 runs before June, he deserves a chance!

Umpire Tucker's hat has blown away a few times in this Test, he may be advised to jam it down even more firmly as the wind whips up even more. Cook steers to ball down to long-on, Martin Guptill flicks the ball back from the boundary before making a mess of the advertising which covers the rope. The batsmen run three. Stokes, who has shed his sweater, is then discombobulated by a delivery which rears up and strikes him painfully on the left hand. Ouch indeed. Don't let them see you bleed, Ben. The grimacing left-hander clips a single to long leg.

James Hudson: I don't know which collapses quicker: me, after a big night out or the England cricket team.

Stephen Byrom: Still waiting for this collapse to be inexplicably blamed on Alastair Cook.

"If you look at Adam Lyth in this series, he's had three really good deliveries. You get those times as a batsman. Whereas you look at Ian Bell's dismissals and they've been so tame. For a senior player, he's getting in such a soft manner. To win the Ashes, you need eight players in form."
