Television replays show just how brilliant a piece of bowling that was from Tim Southee. He produced three deliveries with a straight seam that swung back into Gary Ballance, then scrambled the seam for the wicket ball, which held its line. Masterful control. Cook pockets a single off Henry.

"A quick glance at the field us just how deep in the soup England swim. Four slips, a gully, a shortish point - Ian Bell has more company than a man handing out free fivers. All that after Tim Southee produces a humdinger to get Ballance, one that drew gasps from the press box."

Ian Bell, who has had a rotten Test match so far, arrives at the crease. He owes England, and England need him to make good on his debt. He begins well, hitting a four through point.

"It is like a little off-spinner, which has gripped. It is just of the length that squares Ballance up and nips away and cleans him up. If you look to play the ball to the mid-on area you at least get some bat on it, but if you play it square it can beat the bat."

New Zealand have called Gary Ballance's bluff here. They station Luke Ronchi out on the hook, putting the fear of the bouncer in Ballance's mind. He backs further and further into his crease and then loses his off pole when Southee produces a beauty which beats his hesitant forward defensive prod.

"If New Zealand can bowl it right, the ball is still swinging. The cloud cover has raised a bit since England were bowling, which is good for them."

Brendon McCullum shuffles his pack, bringing on debutant Matt Henry, who really impressed in the first innings. It's a good first over from Henry, bowling a really tight line to Alastair Cook, who manages to work him off his pads for a single.

"67 extras in the New Zealand innings is the fifth highest in Test cricket. 34 leg byes fell one short of the world record."

"If New Zealand can get three or four they will be delighted. It is really important for England to hang in there. They can't lose any more wickets. It is not doing what it was doing earlier in the day, though. It is not hooping."

When a side has batted second at Lord's with a lead of 134 or more, they have won 22 matches and lost just one. Ominous. Tim Southee is zeroing in on Alastair Cook's stumps with that trademark inswinging yorker, but the England captain is strong off his pads and flicks him away for two.

Mark Savile: Very leave-able delivery, on height if not line. If that had been Trott the vultures would be circling. Hope Lyth gets a chance.

Mark: Cue criticism of Lyth. All baying for him to play, against a good attack he gets 2 good balls & should be dropped. Unbelievable.

Another heart-in-mouth moment for Alastair Cook as he gets an inside-edge trying to cut a close and the ball bounces fortuitously over the stumps. Cook got a couple of chop-ons in the West Indies, but he survives here.

Ayelet H Lushkov: So this isn't really the best way to either cement place as opener, or to chase the lead, right? Work to do, lads.

Intel Strategy: Is there an opener in England who plays like an opener?

Jeffrey Yeung: About to say Lyth can take some pressure off Cook by going after it more, now, Cook must step up and stabilize the innings.

In his two previous Tests at Lord's, Gary Ballance scored a century in each: 104* v Sri Lanka in June 2014 and 110 v India the following month.

"Just for a split-second Cook thought that ball might travel right down to fine leg's hands. New Zealand got a bit of luck with the bat, though, so it balances itself out. It is good bowling from Southee, with two short balls and then a fuller one, trying to get Cook off balance."

Cook and Ballance might both have failed in the first innings, but they are in excellent form - both enjoyed very productive series in the West Indies. Shouts of 'Catch!' as Cook takes on Southee on the hook, but he gets away with it, landing safe and running away to fine-leg boundary. The replay reveals closed eyes and a top edge - the England captain was a bit lucky there.

"There's a smattering of Kiwis in the crowd, not shy to jump up and punch the air as Southee pouched Lyth. This, right now, is the game. If England wilt in the next hour, the Test will likely be lost."

It's a tough school, Test cricket, one mistake and you're back in the sheds ruminating on what might have been. Adam Lyth will have to learn quickly if he's not to become Alastair Cook's sixth discarded opening partner. Gary Ballance is the new man, he blocks out the rest of the over.

"He takes it very casually, Tim Southee. It is the first ball he has got in the right area. A promising start comes to an abrupt end for Adam Lyth courtesy of a good nut in and around the off stump."

Just what New Zealand wanted, just what Adam Lyth didn't on his debut. Trent Boult lulls him into a false sense of security with another freebie that is pummelled through the covers, then gets him with a beauty, squaring him up with an away-swinger that draws the edge. Tim Southee, who really does have a good pair of hands in the slips, swallows it, and England are one down.
