This has been England's story so far - a defeat by South Africa, then wins over Thailand and Pakistan:

West Indies have won only one of their past 11 T20 games. But at T20 World Cups, they've won three of their last four against England. Something's missing from them, I think.

Thanks, Jack - it's Mark Mitchener back on live text duty as we turn our focus towards England.

West Indies lie in wait at the Sydney Showground - and a win for England will keep things simple, booking their place in the semi-finals.

But defeat would leave them vulnerable if West Indies were to beat South Africa on Tuesday.

You can read Amy Lofthouse's report of how South Africa booked their place in the semi-finals here.

Can England join them?

Stick here to find out as we start building up to England against West Indies.

Pakistan stand-in skipper Javeria Khan: "In the last few overs we lost our way a bit, it was a slow wicket so we should've restricted them to under 120 and then it would've been a different game.

"We did not execute our plans well or bowl to our field but Wolvaardt played some extraordinary shots.

"It was a good effort with bat, but we have to realise when we have to take charge. We started too late, after I got out there were four to five overs that were not up to the mark."

South Africa captain Dane van Niekerk: "I have to apologise for my reaction in our bowling innings when I kicked the ball. It set a really bad example.

"I am really happy to reach the semi-final. I have to give credit to Pakistan, they gave us a massive go throughout the whole game. They kept coming at us, it was an incredible game to be part of.

"It's only Laura Wolvaardt's third time batting at number five and for her to show her skill like that and getting us to that winning total was incredible.

"She's already an incredible cricketer but I think she will go on to be a legend of the game.

"Our fielding was a better effort, though I let a catch go, and we need to take those half chances. Myself and Lizelle Lee haven't got going as a pair as openers, it would be nice to do that so we can give the middle order more of a platform."

So South Africa join India in the semi-finals.

The Proteas will likely top Group B and face the winner of tomorrow's final Group A game between Australia and New Zealand.

England will now secure their semi-final spot if they beat West Indies in the match coming up next.

South Africa batter Laura Wolvaardt: "This is definitely the most valuable contribution I've made to this team.

"Number five is a new role for me, I'm enjoying it down there and I've got more freedom.

"The total was a bit lower than we would've wanted and we need to talk about how to adapt on these pitches.

"I'm so excited. This tournament has been amazing so far and it's been a real team performance these last few games."

Good on South Africa, they've got themselves to the semi-finals. But I was so impressed with Aliya Riaz in this game and the last game.

South Africa captain Dane van Niekerk lets out a roar of celebration.

All smiles and hugs now, but the Proteas were oddly tetchy with each other for long passages of that innings.

There was a lot of frustration at themselves for falling below their usual standards.

Laura Wolvaardt's sublime 53 was absolutely vital in getting South Africa to a total that proved beyond Pakistan's capabilties.

Without that knock, Pakistan could've pulled off an upset. Plenty for South Africa to ponder before the semi-finals.

Aliya Riaz just scythes the last ball to point for a single.

South Africa secure their spot in the semi-finals with a fairly comfortable win, despite some fairly ropey bits of play.

A fine yorker by Khaka. Pakistan can only pick up one and that's that, barring a load of wides.

Aliya Riaz bashes a low toss wide of long on for four.

You know the six-counter for the tournament? I think we need a dropped-catch counter. I think there have been more drops than sixes.

Aliya dropped on 29published at 19.1 overs

19.1 overs

Aliya Riaz belts a slower ball out to deep mid-wicket but Shabnim Ismail shells it.

Yet another dropped catch by South Africa.

It's probably not helped South Africa, having Marizanne Kapp off the field.

Surely not even the captain can avoid a fine from her team for this.

South Africa players continue to shout and gesticulate at each other.

Imagine the scenes if Pakistan smack 29 runs off the final over to win.

Short from Ismail and Aliya carts it over point for four.

I played in a game for Lancashire against Staffordshire, where I was bowling to Elyse Villani and Danni Wyatt

I conceded 29 off my over, and I didn't play in the next game - I was dropped.
