Canny variations of pace can be a really crucial part of a fast bowler's armoury at this stage in the innings. Sohail Khan keeps Simmons to a single with a clever back-of-the-hand slower ball. He tries it again the next ball, but gets it wrong and is no-balled for an unintentional beamer at Sammy.

Sammy is a ferocious hitter when he gets going but he can be a sticky starter, and Pakistan have got him tramping in treacle at the moment. Sohail induces the frustrated batsman to try a mighty pull, which balloons up in the air over the keeper and runs for four. Lucky.

Irfan, who has bowled well today, to deliver his last over. The West Indies are just struggling for momentum at crucial period at the end of the innings. A couple of mistimed slap shots earn singles, but it's a frustrating over for the batsmen, just three from it.

Good figures for Irfan, 1-44 off his ten.

Another big miss in the field from Pakistan as Simmons gets stranded halfway down the track, but Sohaib Maqsood can't gather the ball cleanly on the turn. Simmons had given up the chase.

Darren Sammy is capable of giving the ball some serious tap and Sohail Khan knows he has to bowl a full length to counteract the batsman's powerful striking. He does well to pin him down - just a single from the first four balls of the over.

Problems for Ahmed Shehzad as he's struck in a particularly sensitive area by a Lendl Simmons shot. He seems to be OK though. Two off a very good over.

West Indies haven't really succeeded in getting after the part-time spin of Haris today (and indeed have lost two wickets trying to do so), but Simmons does what he's been longing to do and deposits him into the stands with a massive slog-sweep.

Good shot, and he's not done yet. He advances down the track and clatters Haris to long-on for another four, and when Misbah tinkers with the field, he picks the gap at square-leg with a powerful sweep for another boundary. Great batting, 15 from the over.

"They have jockeyed themselves into a position where 270 is possible. Simmons is now away and has broadened his range of stroke and Sammy can play big shots."

Afridi's last over - can he produce a moment of magic? No, just more runs as Simmons tickles him to third man for four. 200 up for West Indies.

"I like that if you mishit the ball to a spinner that the boundary is big enough that they can be caught. I don't like seeing a mishit going for six."

Scorecard

Radio 5 live sports extra commentary

Darren Sammy, a very dangerous lower-order hitter, is the new man.

This is the type of dismissal that costs you matches, I'm afraid. Denesh Ramdin has played really well and just brought up his fifty with a cut for four, but having established himself at the crease and with the last 10 overs looming, he gifts his wicket away with a mistimed on-side heave which drops into the hands of long-off. A momentum-shifter.

Shahid Afridi looks a little down in the dumps - it just hasn't been his day today. Simmons flays him for another four with a late cut through point. That cut was so late, if it was a dinner guest, it would have missed drinks, starter and main and arrived halfway through the cheeseboard.

Back to Haris Sohail, who has bowled pretty well in the fifth-bowler slot today. He's unlucky with his first delivery as he finds the edge of Simmons' bat, but there's no slip in and the ball trickles away for two byes. Good sharp running between the wickets has been a feature of this nascent partnership and Simmons does well to pinch another tight single off the final ball of the over. Five from the over.

Shahid Afridi, who has so far bowled seven wicketless overs and dropped two catches, returns, and his below-par day continues when he serves one up in Lendl Simmons' arc and the batsman clears his front leg and swipes him over cow corner for a maximum.

Mohammed Irfan and Wahab Riaz, the two best bowlers for Pakistan, only have five overs left between them. Does Misbah use them now or save them for the death?

He goes back to Irfan. The Windies batsmen have found the tall bowler hard to hit, so instead it's a drop-and-run policy from Ramdin and Simmons - four singles from that over.

Six runs from the last three overs. New man yet to get off the mark. Pressure building, building on West Indies.

Misbah continues to put his trust in pace for these powerplay overs - now he turns to Sohail Khan. The bowler blots his copybook though, feeding Denesh Ramdin right in his strong zone - on his legs, and he pulls sweetly for four. The wicket-keeper is playing a valuable, enterprising knock here.

Will West Indies be worried by their faltering start to this powerplay? Don't forget they have plenty of firepower to come, with Darren Sammy and Andre Russell.

At the moment though, the Pakistani quicks are keeping them pinned down with some really accurate bowling. Wahab coughs up just a single from his latest over.

Mohammed Irfan returns to the attack to try and keep West Indies on the back foot - both literally and figuratively. He begins really well, ratcheting up the pressure on the batsmen with three dots, before Ramdin works a single to square leg. He then pins new batsman Lendl Simmons with two more dot balls. The momentum is back with Pakistan at the moment.

Lendl Simmons is the new man for West Indies. Four runs off Wahab's over - an excellent start to the powerplay for Pakistan.

It doesn't look like Bravo is going to be able to continue. He's been taken off the field on a medical cart. What bad luck for the Windies - losing a batsman just after taking the batting powerplay.
