The Kevin Pietersen-like flamingo shot comes out. Sarah Taylor lifts one leg and times a lofted four through the leg side. The next boundary isn't as elegant, but equally as effective as she clobbers four down the ground.

And again! Three fours in a row. The 200 partnership is up.

It's tough to separate them... but the second of these fours is my favourite of the day so far. Wonderful stuff.

Sarah Taylor's 100 is up now too, off 80 balls. Brought up with a single and a loud scream. Her first ODI ton since 2013. Take a bow.

Beaumont opens her shoulders now she's reached three figures. It almost endss in disaster when a catch drops just short of mid-wicket. Clever aggression is what's needed now.

You can see the relief on her face. She would have been feeling like that she hadn't performed as she would have liked in the early part of the tournament, but she was been brilliant today.

There it is. Tammy Beaumont steps to the side and steers four down to fine leg. What an innings - 100 off 118 balls. The third of her career. Don't rule out an attempt at beating her career-best 168 not out.

I tell you what... Sarah Taylor is as good to watch as any batsman in the men's game. She's a proper touch player. This time she extends the levers and lofts four over extra cover. Brilliant.

England look absolutely brilliant today and South Africa have no answers. It's so difficult to bowl at players who hit the ball all around the wicket.

Better timing than a Swiss watch from Sarah Taylor...

Tammy Beaumont has barely been in her crease today - she's always walking at the bowling. Would it restrict her if the wicketkeeper stood up to the bowling? The 150 partnership is brought up when Sarah Taylor steers four through third man. The very next ball, Kapp is flicked over square leg for four.

The over ends in scintillating style as Beaumont does indeed stay in her crease and ramps four over the wicketkeeper's head. Glorious.

Sarah Taylor looked in pristine form the moment she walked to the wicket...

Oh yes. Yes. Yes. Yes.

Sarah Taylor plays an absolutely wonderful shot as she walks across her stumps to Ismail - regarded as the fastest bowler in this tournament - and lofts four over the square leg fielder. Class. Pure class.

Ismail and Kapp could come back on after drinks, it might be South Africa's only chance to get back into the game. They don't look like taking a wicket at the moment.

Tammy Beaumont is lucky there. Moseline Daniels, a left-arm seamer who has more pace than first appears, shapes one into the right-hander's pads. Not out. Probably the correct decision given Beaumont's large stride down the wicket. Not a bad shout though.

The runs are flowing as England begin to think about a total in excess of 300. Sarah Taylor belts four back down the ground, moments after Beaumont also found the rope. The charge is on.

Martin Duck: Why oh why is there no TV umpire at a World Cup!? Should be a standard for such a major tournament.

The shot of a woman in form, with a dash of MS Dhoni in its execution.

Tammy Beaumont and Sarah Taylor are enjoying themselves out there - the smaller frame of Beaumont leaning on her back at beaming back at Taylor between overs.

Is Tammy Beaumont on for a hundred? She's been busy in the crease, walking at the bowling and here she whips four through the leg side. Sarah Taylor holds up her end of the run-scoring bargain by getting down on one knee and flicking four over her shoulder. The medium-paced bowler, Chloe Tryon, looks helpless.

Here's one Tammy did earlier...

Australia, without skipper Meg Lanning, are easing into the groove against Pakistan at Leicester. The Aussies are 121-3, with Ellyse Perry unbeaten on 42.

In Derby, unbeaten India are 106-2 against Sri Lanka. Wins for Australia and India today would have them pretty close to the semi-finals.

Khaka's back into the attack. She's been no Brazilian playmaker so far - she's more of a French water carrier. Nothing spectacular, that's for sure. Six from the over as England continue unperturbed.
