Richard M: Stuart Broad would have reviewed that.
Ian Bell is the new man.

"Holder has to be smart and be patient bowling on flat wickets and that was beautifully bowled. The West Indies needed that wicket because bowling at Cook and Ballance late in the afternoon they would be scoring hundreds. Holder has the height and I think he has the heart, he just has to stay focused and keep working on his game."
This is the kind of dismissal that satisfies a fast bowler's most primal instincts. Fast and straight from Holder, it beats Gary Ballance for pace and swing, hurries through the gate like a postman pursued by a particularly fierce Alsatian, and wallops into the top of off stump so hard it breaks it in two. Comprehensive. Holder roars in delight., England two down.
Marlon Samuels looks pretty mean and moody in his dark shades and super-tight, pec-hugging shirt but his bowling in this series has been decidedly toothless. Too short, too slow and Gary Ballance ups the tempo with a thumping cut for four and a huge, strong-armed six over deep-midwicket.

"Holder has to be a batting all-rounder who will be a third or fourth seamer, because he's not going to get the five-fors like a fit Kemar Roach would do."
Jason Holder was stretchered off in apparent agony in the last Test - we thought we might not be seeing him again for many months but here he is fit and firing. Cook, who has advanced sedately this morning, picks up four with a confident cut through point.

"When Ballance walks out to bat in the second or third over, with his natural game - his back-and-across, his stillness - he looks adept as an opening batsman."
Jamie, thank you. Some old-school drinks being taken there - no bottles of fluorescent isotonic beverage for the West Indies, just a woman with a jug of water and a stack of polystyrene cups. Marlon Samuels to continue with his leisurely off-spin - there's a bit of turn too, just getting one to squirt off the outer edge of Gary Ballance's bat, but it flies safe.
England 22-1 (12 overs) after winning the toss
Batsmen: Cook 12, Ballance 8
Fall of wickets: 0-1 (Trott 0)
Bowling figures: Taylor 5-3-12-0, Gabriel 4-1-6-1, Holder 2-0-3-0, Samuels 1-0-1-0

A nice square drive from Ballance off Holder brings him two. Just the 12 overs then in that first hour and let's hope the energy drinks quicken things up. Over to James Gheerbrant to take you through until lunch.
Sergeant Major Marlon Samuels makes it a double change. Even if there are no salutes today, he will provide some much needed impetus for the over-rate with his run/amble-up of three paces.

Ex-England spinner on BBC Test Match Special
"I'm convinced that the West Indies have said that this is how they're going to bowl at Alastair Cook - just putting it outside the off stump all day and waiting for Cook to come to them. He has nicked a lot of balls over the last 12 to 18 months, but I think Cook might be up to the task today."
Despite that 6ft 7in frame, Holder is only in the early 80's mph-wise. He tempts the batsmen outside the off-stump but England's two most patient players are at the crease and they want to still be there at lunch.
Ed Smith
Ex-England batsman on BBC Test Match Special
"Trott's was a really bad dismissal. It's always a worry when the opposition announce how they're going to get a player out and then it works out that way. The pattern of Trott doing his walk into the ball and fending it has become very worrying."
A maiden from Taylor and we're now going to have the first change, as the gargantuan figure of Jason Holder comes into the attack.

"I feel for Jonathan Trott. He shouldn't be opening the batting, he's a number three. It almost seems like a sympathy pick to me."
Ryan in London: A quiet Friday has led to a moment of inspiration. To the tune of 'American Pie' by Don McLean:
Off you pop Mr Jonathan Trott,
We thank you for the good times, but now you've had your lot,
Let's bring Adam Lyth in - and see what he's got,
And give this Yorkshire batsman a shot,
Give this Yorkshire batsman a shot.
Ballance has a well-worn bat, the blade is almost completely red with ball marks, the majority of which are from the middle. Good rotation of the strike from the two left-handers against Gabriel, who has produced a fastest delivery of 92mph already this morning.
