England are back in action on Wednesday, taking on South Africa in Bristol. Next Sunday it's Australia on the same ground.
England captain Heather Knight: "We're really pleased. It was a very good wicket and thought we might have let them get a few too many, but actually we bowled pretty well.
"I'm really chuffed for Sarah Taylor. We knew she was batting well but to see her do it in the middle was really nice to see.
"It's great to have Loz back. The batters are playing well and making selection very difficult."
Player of the match Laura Marsh: "It's always hard to miss out, but it's great to get a chance today and it's brilliant to get some wickets.
"It's always nice when it turns. They had a few left-handers so it's good to get it turning away from the bat.
"The team is playing really well. We'll take lots of confidence going into the next game."
Yep, it's the next three games that will really shape England's World Cup campaign. South Africa, Australia and New Zealand. At least one win needed from those games.
And that's all she wrote. Sarah Taylor strolls down the track, lofts the ball to the straight boundary and shakes some hands. England have bounced back from losing to India with two big wins. South Africa next. The real business begins.
Nat Sciver the new batter, but might not face a ball. Taylor pulls for four. Only three to win. This won't go into the next over...

That's an anti-climax. Quite possibly, Heather might have got a little too excited. The skipper's in a rich vein of form though.
What a way to go. Heather Knight can't finish the job, somehow pulling a Chamari Atapattu long hop straight to Harshitha Madhavi. The skipper, though, has followed up a ton with this knock. Her team are pretty much there.
Full toss. Four. Start the car.
Sarah Taylor is toying with the Lankans now. Inside-out over cover for four, then a reverse sweep. Back-to-back boundaries. England have taken six fours in 10 balls.

The England coach Mark Robinson must be so pleased with this performance, it's been almost exactly what he would have wanted to see.
Heather Knight looks like she might be keen to get this one done now. Shots at most deliveries, a four carved through the off side, then a whip off the pads behind square on the leg side, a full toss helped around the corner. Three boundaries underneath the golden Taunton sun. Only 25 needed now.
Welcome back, Sarah Taylor. A year away from international cricket, Taylor posts a half-century in her third game back. A hug from Heather Knight, applause from her team-mates. Now to see it home with a red-inker.
David Wallace: So good to see Sarah Taylor batting strongly again. 8 wkts victory would be terrific
Oh yes. Heather Knight could bring the end of this about pretty quickly. A full-bunger from Madhavi, easily picked up over the deep mid-wicket fence to a big cheer from the Taunton crowd. Taylor wants a second run that would take her to a half-century, but Knight turns it down. Sensible.
The TV commentators are noting how well Heather Knight deals with the captaincy. She certainly seems like she's in control of everything - from the cover drive to the expectation of a World Cup on home soil.
Anyway, Stephan Shemilt's back to see you through to the end of this match.
And here's the shot I said should be played to all kids out there. Master this one and you're halfway there. Gorgeous execution.
If I had to pick a clip to sum up Heather Knight's innings, it's this one. She's made the tricky look easy. Miss this and she's out - but she was never going to miss it, was she?
A 12th ODI half-century for Heather Knight, who is averaging more than 100 in this calendar year. Stepping up when it matters.
India's 169-9 is all of a sudden looking like a winning score at Derby as Pakistan have slumped to 29-6 in pursuit.
Opener Nahida Khan is unbeaten on 11 off 44 balls, but she is the only Pakistan batter to make it into double figures so far.
Australia are in a much stronger position at Bristol at 98-2 off 25 overs in reply to New Zealand's 219-9. Meg Lanning and Ellyse Perry currently at the crease for the Aussies.
Heather Knight and Sarah Taylor are enjoying themselves in the Taunton sun. The runs are coming along easily, they're having a chat between overs, both smiling. Life's good.
This is resembling a public net session now. England have the sunroof down, the music blaring and are cruising along the open road. Easy pickings.
This. Is. Some. Shot.
Siriwardena is bowling her off-spinners with a cap on. I'm not a fan of bowlers wearing caps. I just don't rate them - like pony-tailed centre-halves. I should add that Siriwardena has taken more than 100 ODI wickets in her career so she's more than useful - not that she's troubling Heather Knight who sweeps four to the boundary.
This is a fine example of how nimble Sarah Taylor's footwork has been today.
That's lovely, Heather Knight. The England skipper gets her foot to the ball and pushes it through the covers for four. Watch and learn, kids.
Another over passes and England are another four runs better off. They are in as much control as a toddler with the TV remote control. This is all theirs.
What marks out Heather Knight and Sarah Taylor is their foot work. Both are nimble on their toes and quick to get into position against the slower Sri Lankan bowlers.
If England's fielding needs improvement, I'd wager their batting looks as good as any now Sarah Taylor is back and in form. She and Heather Knight are effortlessly ticking the scoreboard over, knowing they require less than 100 now with the likes of Nat Sciver and Katherine Brunt still to come. A strong middle order.
These two are developing a nice little showreel already. Below you'll see Heather Knight hitting straight down the ground, and in the latest over to pass us by, Sarah Taylor pulls a majestic four through the leg side. The smile on her face after the ball flies off the middle shows she's enjoying it out there.
It looks like Heather Knight did indeed hit that one - she's gotten away with one.
She celebrates with a lusty blow over mid-wicket for four.
I like Heather Knight. She's got a natural air of authority about her. Proper steel and grit a la Ricky Ponting. You wouldn't cross her.
Now then. It didn't bounce. Knight tried to play a sweep and the ball ended up in the keeper's gloves. Given not out. Was there bat in that? The umpire didn't think so. England's serene progress continues. It's barely a contest. Here's Marc Higginson.
The left-arm spin of Sri Lanka captain Inoka Ranaweera comes into the attack, Knight greeting her opposite number with a wallop through the on side for four. What's the keeper appealing for here? A catch? I'm pretty sure that's bounced. Nothing doing.
Still the off-spin of Ranasinghe, Sri Lanka now with reinforcements on the leg side. Taylor, with an open stance, still manages to find a gap. Four singles from the over.
A couple of times Heather Knight has gone right back on to her stumps, working the ball. She'll be in trouble if she misses it. Having said that, one suspects that any problems England may encounter during this chase would be of their own making. Run-scoring does not look tricky.
End of the powerplay, field goes back as some younger members of the crowd bosh together inflatable sticks to make a din. Next in Nat Sciver waits with her head resting on her hands. Three singles from Ranasinghe's over.
Pakistan have made a disastrous start in reply to India's 169-9 and are currently 14-4 at Derby. Left-arm spinner Ekta Bisht has taken 3-3 from three overs while Jhulan Goswami has picked up one.
Australia are looking a lot more confident against New Zealand at Bristol and are 49-1 in the 14th over in pursuit of 220 for victory. Nicole Bolton (26) is the batter out having been caught by Holly Huddleston off the bowling of Anna Peterson.
Cute from Sarah Taylor, a scoop to the vacant fine leg boundary for four. It's celebrated with a blast of Muse by the DJ. Miles better than the 90s naff-pop we had earlier. Taylor is absolutely drilling the ball, only being denied by pesky fielders. I still reckon England could get these in about 30 overs.
Knight has only just arrived, but she's clever enough to see the gap behind square on the leg side. A little lap gets her off the mark with a boundary. That wicket of Lauren Winfield is even more disappointing for England given the touch she looked in...
