Heather Knight admitted England were “fighting for our lives” at the Women’s World Cup after a shock seven-run loss to the West Indies.

England slumped to a second straight defeat in New Zealand, failing to chase down the 226 victory target to leave their World Cup campaign in the balance.

Shemaine Campbelle’s 66 and Chedean Nation’s unbeaten 49 helped steer the West Indies to 225 for six, but England faltered on an eminently achievable chase.

England skipper Knight called on her side to sharpen focus to shake off a demoralising opening to the tournament.

“We need to have a knockout mindset now,” Knight said.

“The next game is crucial. So we have to bring that mindset of needing to win every game and that simplifies things.

“And hopefully that will sharpen people up, sharpen people’s minds to what we need to do.

“Because at the moment we’re fighting for our lives in this tournament.

“There’s a lot of experience in this group, we’ve lost games before and we know we can’t dwell on defeats too much.”

Tammy Beaumont hit 46, with Sophia Dunkley, Danni Wyatt and Sophie Ecclestone all reaching the mid-30s.

But England’s middle order failed to launch, teeing up a second quick disappointment at the top of the competition.

Shamilia Connell took three for 38 as England wound up 218 all out.

England will face South Africa in Tauranga on Monday, knowing full well improvements must come, and fast, to turn the current troubles on their head.

“First and foremost, we can’t linger on it too much,” Knight said.

“We’ve made it tricky for ourselves, but there’s no way are we out of this World Cup yet.

“So we have to focus on the next game, get what we can from this game, park it and move on to be ready for South Africa.

“We were clear on our plans – we just didn’t quite execute, at times.

“They finished pretty strongly, and it’s something we can do better with the last 10 overs.

“It’s something we’ll look at and keep improving, our back-end stuff.”
