Vince in as England lose opening gun

Australia will have one less power-hitter to curtail in their hotly-anticipated World Cup clash at Lord's after captain Eoin Morgan confirmed opener Jason Roy will not be risked for the match.

Roy has been sidelined for England's last two games after tearing his hamstring earlier this month, but encouragingly batted in the nets on the eve of the Australia game after returning positive scan results on Monday morning.

But Morgan said it's too soon for the destructive right-hander to return.

"We'll monitor his progress during the week and assess him then as that unfolds," said Morgan.

"He's Jason Roy – of course he's a big loss. He's an outstanding performer for us. The way he plays epitomises the way we play as a group. He's been in the team for a very long time."

James Vince, who has made 14 and 26 in the two games he's played as Roy's replacement, will hold his spot at the top of the order.

Australia skipper Aaron Finch knows the danger Roy poses as well as anyone having forged a successful opening partnership with him for county side Surrey.

But he insisted they hadn't overlooked the skill of Vince, who struck a half-century against Australia in warm-up game at the Rose Bowl in the lead-in to the tournament.

"Jason's been a huge part of their planning and a huge part of their success over the last couple of years," said Finch.

"He obviously plays a high tempo and high-risk game, which when it comes off is super-influential on the game.

"James played really well in the warm-up game against us and got (64) down in Southampton. He's proved to be a class top-order player in his own right … it would be really naïve to overlook someone of his quality."

That fourth-placed England have taken a conservative approach with their star batsman is no surprise given their final games are against the three sides in the other semi-final spots – Australia, India and New Zealand.

The trio are generally considered the hosts' biggest threats for the title.

Should England fail to win at least one of those games, Sri Lanka, Bangladesh or Pakistan could sneak past them into the top four.

But a measured Morgan, while acknowledging the extra edge England-Australia games generally hold, played down the importance of Tuesday's result.

"It's not must-win yet," he said. "We don't need to win every game to get to the semi-final.

"It's another game where we try and produce a performance that's worthy of winning at Lord's against Australia.

"They (England) are very excited about getting back on the park tomorrow to try and produce something that everybody's used to seeing us play – and if that means that we win the game, great."

Recent history is in England's favour, having beaten Australia in 12 of their 14 most recent 50-over games and failing to lose back-to-back ODIs on home soil against all-comers in more than three years.

Morgan put their ability bounce back down to self-reflection.

"Primarily it's trying to keep things as simple as possible," said the batsman. "Being truthful and honest with our previous performance and trying to learn and rectify the performance almost immediately.

"I think because we have quite a strong identity in the way that we play, I wouldn't say that we can flip back to it immediately.

"But it almost becomes a little bit easier and less confusing to guys, the direction in which they need to go (after a loss)."
