And that's where we leave it for the day. We'll do it all again tomorrow - with play starting at 15:00 BST, we'll be back on duty here from 14:30.

Two good sessions could - and should - put England on the brink of a first away Test victory since Kolkata 2012. West Indies need some inspiration from somewhere - I'd expect them to get another pre-match "fire and brimstone" talk from Sir Curtly Ambrose tomorrow morning. Bye for now.

Mel, North London: Just to redress the balance, could you make clear that some England fans love and appreciate Test cricket, are enjoying this match and are hoping England can turn this good position into a winning one?

Apologies for the TMS line going down - you'll be able to download Aggers and Geoffrey's review of the day via the podcast page later.

West Indies began day three on 155-4, still 244 behind England - and while Shivnarine Chanderpaul was dislodged for 46, the rest of the innings belonged to Jermaine Blackwood, who rode his luck a little but forged ahead to compile a maiden Test century. However, he lacked support at the other end as the last five batsmen added just 32 between them, leaving Blackwood high and dry on 112 and England with a first-innings lead of 104.

Sadly, it was the same old story for Alastair Cook and Jonathan Trott, who both fell cheaply, while Ian Bell may only have himself to blame after a needless run-out. But Gary Ballance (44 not out) and Joe Root (32 not out) have added 64 as West Indies rather lost heart in the last hour or two, and England are now "net" 220-3 in a one-innings match with two days remaining.

Craig Stevanato: 24 overs of spin, 30 mins extra, yet still 5 overs short. Not acceptable. Penalty runs + big fines + bans for captains required. Fans pay to see 90 overs in 6 hours, not 80-odd overs in 6.5 hours.

As you may be aware, TMS's line to Antigua went down just after the close of play - they're working to restore it as soon as possible.

If you missed today's lunchtime feature celebrating James Anderson's 100th Test, "The Real Jimmy" (featuring Graeme Swann, BBC Radio 1's Greg James and Anderson's agent Luke Sutton), it's available on the TMS podcast page.

Chris Parker: Re: Firas (22:21): Make Root captain as "our best batsman"? Because that's what we thought with Cook, and look what it's done to him.

Jimmy: Drop Cook, play Lyth and make Root captain.

billybunter3rd: Root will be next captain but needs 18-24 months' more experience, which is why selectors want Cook stay 'til then.

West Indies batsman Jermaine Blackwood on Sky Sports: "It was hard, I took a couple of blows, but that's why it's Test cricket. It's a very big difference scoring a Test century, it's a very important milestone for me. No-one remembers you for half-centuries. I'm looking forward to many more."

On Ben Stokes, whose no-ball reprieved him on the way to his century:

"Ben Stokes and I go back to the 2010 Under-19 World Cup. Ben Stokes is all right, Ben Stokes is my boy."

Full scorecard

Well, it was a more entertaining day than yesterday, but it still drifted for long periods. England will start day four "net" 220-3 - and will be aiming, you would hope, for an afternoon declaration to allow them time to force victory.

C.J. Henstock: C.R.A.B. de Villiers would be a shoo-in for the Crustacean XI.

Christo EL: Crustacean XI players tend to go into their shells when going gets tough and then look like fish out of water when they re-emerge!

It looks as though both sides are going through the motions, as Samuels bowls a few wide of Ballance's off stump, he's not too interested until he chips a single off the last ball.

How do you solve slow over-rate problems? Penalty runs? If a team's five overs short, why not give the other team 25 runs - that would soon eradicate the problem.

"I think the game needs to do more to get to grips with poor over rates. Something needs to be done on the day."

Holder bowls a no-ball, never a good start to the over, while far more interesting news is that the Antigua & Barbuda PM has moved on from selfies with Barmy Army fans to selfies with the dancing girls. Oh, the trappings of power... Back on the pitch, some hard running takes Ballance's score to 43, and even though it's only 22:29 by our clocks, it looks as though the players are ready to walk off... until the umpires force them back on.

We're still going to have lost five overs today, despite 24 overs of spin so far today. Hardly cricket's finest hour.

Paul in Spain: Erm, we are 200 runs ahead with seven wickets in hand, what is going so wrong? Why is everybody so down on England? And why is Tredwell with easily the best bowling figures in the first inning being marked for the chop? Have any of these critics ever actually played or even watched live cricket?

The teams, collectively, are going to be about five overs short of their target of 90 today, not that you'd know it from the players' body language... Samuels to continue, but there are wide open spaces in the leg side for Root to pick off a single just about anywhere. A single from Ballance stretches the lead to 213.

"When you are 100 runs behind, you have no option but to bowl your best bowlers into the ground. The only way you can win is to bowl the opposition out."

The Antigua & Barbuda PM Gaston Browne (who was interviewed on TMS earlier) is now posing for pictures with a fan in a Barmy Army shirt. Having leaked plenty of runs with spin on at both ends, West Indies turn back to Jason Holder at the Sir Andy Roberts End, which puts the brakes on a little - but has the game gone away from West Indies in the last hour?

Firas: Why not make Root captain? Arguably our best batsman and brings a relaxed approach to the team. He can't do worse than Cook...

Tom Tuthill: Will everybody calm down - we are nearly 200 ahead with two days to go. Victory is in the bag.

"West Indies won't be in this contest for long if they carry on in this vein."

More easy accumulation against Samuels, this day's play is ambling towards a conclusion with England firmly in the driving seat. Meanwhile, at the back of the TMS box, it sounds as though Geoffrey Boycott is coming off the long run, giving an update to 5 live listeners...
