England quick Jofra Archer will keep up his aggressive approach in Sunday's World Cup final against New Zealand after his bouncer left Australia's Alex Carey with a bloodied chin in Thursday's semifinal at Edgbaston. The fast bowler gave England a great start by dismissing Australia captain Aaron Finch for a golden duck before knocking off Carey's helmet with a short delivery that required six stitches on his chin. "You don't always mean to hit them," said the Barbados-born 24-year-old. "It can be a wicket-taking ball or a dot ball. When it hits them you feel a little bit bad for doing it, but it's cricket and I don't think he'll be the last person to get hit." Known for his ability to crank up speed without any visible effort, Archer has added the 'knuckle-ball' to his armory and deceived Glenn Maxwell with a slower delivery in the semifinal. It is, however, his pace and bounce which troubles the batsmen most and Archer said short balls would always remain a major weapon for him. "I try to use my two bouncers every over anyway. It wasn't just a set plan. I do it all the time." Off the field too, Archer involuntarily created a flutter when some his old tweets resurfaced and looked eerily accurate in terms of his prediction for the World Cup. After he knocked off Carey's helmet, his 2013 tweet saying "All batsmen buy 2 helmets cause when we meet they will be in use" started doing the rounds. But Archer, 24, denied being a Twitter Nostradamus. "I have seen it but I don't know why it should be a big thing," he said. "It's just social media. That's all it's there for. "I used to do it when I was just watching cricket back home... They are just recycled. Some are from series, some from World Cups, stuff that just happened." Despite Archer having played only 13 One-Day Internationals, former England captain Michael Vaughan expects him to make his Test debut in the Ashes series against Australia next month. Archer, who has been battling a side niggle for a while, said his focus remained on helping England triumph at Lord's where they will bid to win their first World Cup. "After Sunday, I'll probably answer that (Ashes prospects) but for now I'm just focusing on trying to win the final," he said. "I'll keep soldiering on. I have been for a few games now and it's not got any worse." — Reuters
