Mark: Cook's technical flaw remains and shows no sign of being rectified. Every bowler knows to pitch it up around off stump.

Adam Tillsley: Cook out cheaply again. Surely this can't go on much longer? He's so out of form it's incredible...

Full scorecard

West Indies' body language show their tails are up, there's a spring in their step - an overstep in Roach's case as he bowls a no-ball to Ballance, and then frustration as the left-hander fences and misses at the last ball of the over.

Thomas Huysinga: There's a Dutch saying that goes 'a donkey never steps on the same stone twice'. Not quite sure what that makes Alastair Cook.

Football Fragmento: Vaughan says on TMS that Cook looks great. Next ball he's out. Commentator's Curse or what.

Andrew Samson
BBC Test Match Special statistician

"Of Jerome Taylor's 108 Test wickets, 19 of them have been the opposition captain. It's the highest percentage (17.59%) of any bowler in Test history."

New batsman Ian Bell shows the full face of a back-foot defensive shot to Taylor as the ball whizzes by first ball, then one nips back, nearly cuts him in half and keeper Ramdin can't hold on as it disappears to the boundary. It's signalled as leg byes though, so can't be put down as a chance, but was mighty close.

Michael Vaughan
Ex-England captain on BBC Test Match Special

"His foot movement was good, he just prodded at the ball. It was the first ball Taylor bowled round the wicket, and that's the angle that causes Cook problems. Taylor's getting it as full as he can, it's not safe bowling but he draws the drive."

A tentative checked drive does for Alastair Cook as he edges Taylor to gully and is caught by big Sulieman Benn. Not a start to the innings that either Cook or Trott will remember fondly - the knives will be out for both of them now.

In England's favour, they are "net" 124-2. Ballance managed to open his account with a three through mid-wicket before Cook fell.

Kevin Baker: What a delivery by Taylor. World class. Not much Trott could do.

James Gutteridge: Can we just admit Trott is no opener and give Lyth the chance he deserves?

Will Morrall: Send Trott home. He's not even close to being the same player. Moeen's back too - no brainer.

Gary Ballance is the new batsman, walking to the middle while the West Indians celebrate. For now he's the non-striker as Cook sizes up Roach, who runs up in the manner of the former star sprinter Michael Johnson (with his head well back) but is nowhere near as quick,,, Cook adds a couple to his score.

"He's on the move, which is not great. But I think he was playing towards mid-on, which he always does. It's not great against the new ball. I don't think he's an opener. If I was Adam Lyth, I'd have a good sleep tonight and go to the nets early tomorrow morning."

Jonathan Agnew
BBC Test Match Special

"It wasn't one solid movement, it was a walking shot, playing towards mid-off. He was squared up, the outswing has done for him again."

Listen to TMS commentary via the audio icon (available in UK only).

Oh, no - Trott edges to the keeper for the second time in this match, trying to work a swinging delivery from outside off stump to leg. I can hear the knives being sharpened already.

Geoffrey Boycott
Ex-England batsman on BBC Test Match Special

"It's difficult to create pressure when there are only a couple of really good bowlers. Cook is used to the ball going across him: the that gives him the most trouble is the one that just holds."

Jonathan Agnew
BBC Test Match Special

"You can feel Cook trying to get forward rather than across the crease. Taylor is just finding a little bit of movement at the moment."

Listen to TMS commentary via the audio icon (available in UK only).

Cook is not quite entirely fluent yet, inside-edging Taylor onto his pad, while he's slightly off-balance (as opposed to being off-Ballance) as he hoicks him through mid-wicket for four. A single takes him to 11.

On Twitter:, external Benn is Anderson's first wicket caught at short leg since Iain O'Brien at Manchester in 2008 (his 78th wicket).

No rain yet, but the floodlights are on as Trott steps well across his stumps to work Roach for two - almost like the way Hashim Amla played England at The Oval three years ago, stepping across to the off side each time to bring lbw out of the equation.

Ben Hoare: Trott and Cook to get a century each with a stand of 225/230. It'll happen.

David: Moeen Ali has scored one Test hundred in 10 innings, never scored a 50. Why is he a guaranteed pick?

If you didn't hear earlier, all-rounder Moeen Ali has been added to the England squad for the final two Tests in the West Indies.

The 27-year-old left-handed batsman and off-spinner was not included in the original 16-man party because of a side stain suffered during the World Cup.

However, he made 62 and four on his comeback in Worcestershire's season-opening County Championship defeat by Yorkshire this week.

The England and Wales Cricket Board said Moeen will join up with the squad in Grenada on Saturday, before the second Test begins on 21 April.
