Jason Behrendorff has emerged as the newest member of Australia's first-choice fast bowling trio in their World Cup defence following his stellar outing at Lord's on Wednesday.

The 29-year-old fast bowler claimed his maiden five-wicket haul in one-day internationals to help Australia complete an emphatic 64-run win over England.

Whether Behrendorff would be on the tour if not for injuries to fast bowling spearheads Josh Hazlewood and Jhye Richardson is up for debate.

This was just his second game of the tournament, having come in for Nathan Coulter-Nile.

But he has now wiped out any doubt about his worth to the defending champions after adding his name to the famed Lord's honour board.

All it took was a leap of faith to hand Behrendorff the new ball and break up regular openers Mitchell Starc and Pat Cummins.

"It was huge. That's where one of my primary strengths lies, bowling up front and swinging the new ball," Behrendorff said.

"It was great to be given that opportunity and to repay the selectors with a wicket early doors.

"The really positive thing is both Mitch and Pat have played a lot of one-day cricket, so to be able to chat to them about how they go about it, especially through the middle overs and how we can look to continue to take wickets.

"I'd love to be able to grab a few [kilometres] off Mitch, that'd be nice. Those things are really important, to be able to work together, and to be able to execute those plans out in the middle."

The affable Behrendorff still has ground to make up on his fellow fast-bowling cartel members on the road to becoming a household name.

Starc's searing yorker to remove Ben Stokes is likely to get more airtime than the Behrendorff bullet which split the defence of James Vince.

But that will not bother Behrendorff, who is content to be the less glamorous half of Australia's left-arm duo. In fact, that quiet achiever role sits quite well with the Tuggeranong Valley junior.

All he needs now if for Australian coach Justin Langer to persist with the pairing, amidst all the bizarre hoopla about having two left-armers in one XI.

"We don't often see it but I don't see why we can't. Sometimes we play three right-armers, so why can't we play two lefties?," Behrendorff said.

"Mitch and I do different roles throughout the team, so it was really good that we could play together. Mitch and I picked up nine wickets between the two of us so it worked quite well there.

"The main thing is Mitch and I are really happy to be able to play in the same team together. To have two lefties, hopefully we can see more of it, that would be great."

And wouldn't the Behrendorff touring clan - Jason, his parents, wife Juvelle and baby son Harrison - like to see more spells like this.
