England defeated Zealand by 87 runs to become the first team to qualify for the semi-finals of the ICC Champions Trophy match, here today.
England's victory means they will top Group A whatever happens on Saturday against Australia, by virtue of having won their two matches, and will play their semi-final at Cardiff on June 14.
England secured their passage to the ICCChampions Trophy semi-finals with a game to spare after another inspiring display with both bat and ball helped them progress in challenging Cardiff weather.
Once Taylor was gone, New Zealand completely collapsed, thanks in large to Liam Plunkett, as they went from 168/4 to being bowled out for 223.
Martin Guptill (27) and Williamson dug in before the former edged an intended drive off all-rounder Stokes to Root at a wide slip.
England were in danger of falling short of 300 after Joe Root (64), Alex Hales (56) and Ben Stokes (48) all got out when well set.
Three-wicket hauls from Adam Milne (3-79) and Corey Anderson (3-55) - returning to the scene of his 2013 debut - threatened England's momentum as Williamson chopped and changed his bowlers.
Stokes (48) and Jos Buttler (61 not out) kept the scoreboard ticking over before England were dismissed in the 50th over for 310, probably 30 runs short of expectations.
Plunkett inflicted the most damage as he finished with four wickets, while Ball and Adil Rashid took two wickets apiece.
But once Williamson was out, edging a ripper of a delivery from Mark Wood (1/32) to wicketkeeper Jos Buttler, it was downhill for the Black Caps.
England recovered later that year to beat Brendon McCullum's tourists 3-2.
Jason Roy (13) was sent back early by Milne as the opener tried to walk across his stumps to a quick delivery which knocked his stumps as he tried to flick the ball over the leg side.
New Zealand now need to beat Bangladesh on Friday night (NZT) and hope a hugely impressive England do the same to Australia to make the semifinals. The ball was going out of the entire ground until it hit the camera gantry.
Hales was initially the driving force, but as his boundaries dried up Root took over by twice chipping Mitchell Santner for six over long-on - an ominous sight perhaps for England's spinners, who must try to keep the Kiwi big-hitters in check later on.
After Buttler headlines powerful batting display, Plunkett masterminds 87-run rout of New Zealand.
Root and Hales, following up their stand of 159 in last week's win over Bangladesh at The Oval, soon got to work again.
The Black Caps will be desperate for a victory after their opening game against Australia was rained off. They strung together a healthy partnership of 81 runs before Hales departed.
"I think the way New Zealand went about playing their cricket was probably closer to the way we go about it".
"I thought we looked like we were getting about 340 at stages, but fell away towards the end, which is disappointing".
