Anybody who can get Steve Smith rattled at the peak of his form is special. And, make no mistake, Jofra Archer is special.
The Barbados-born pacer, who made his Test debut for England in the second Ashes Test against Australia at Lord's, might have picked up just five wickets in both innings of the drawn Test. But, the intimidation factor that the 24-year-old created in the minds of the Australian batsmen is bound to have a massive impact on the rest of the series.
Before the Test, Australia coach Justin Langer said it'll be interesting to see how Archer, who had only played limited-overs internationals till last week, would cope with the rigours of bowling long spells in white flannels.Challenge accepted, Mr. Langer.
Archer bowled a total of 44 overs in the entire Test – 29 in the first innings and 15 in the second — the second most by any English fast bowler on Test debut since 2007 after Chris Jordan.
And they were fast, hostile, fearsome spells.
Archer smacked the ball on the neck of dangerman Smith, ruling him out of the final day of the Test and effectively the third Test with it. Archer struck the grill of his concussion substitute Marnus Labuschagne, who needed a concussion test himself. Archer had Cameron Bancroft ducking, Usman Khawaja swaying, Tim Paine pulling only to see him return to the pavilion.
In his maiden Test appearance, Archer was blockbuster stuff.
"He's come in and made a massive impact," England captain Joe Root said.
"He's added a different dynamic to our bowling group and given Australia something different to think about. It's pleasing to see someone come in on Test debut, shake up things and live up to the hype – even some of the hype he put on himself. It makes for a very interesting last three games," the skipper added.
And so the dynamics of the series have changed. Australia dominated the first Test in the absence of Archer, and felt they had the grip on the hosts. But Archer ensured England found their spark and bounced back at Lord's, and although they didn't get the victory they were after, it has given them a shot of self-belief of turning the series around in the next three Tests.
"Things can change very quickly in sport. At the start of the week we wanted a big response and we have definitely done that," Root said. "It felt like we put them under huge pressure. It shows how much we're in this series."
All thanks to one man, predominantly.
"He (Archer) makes things happen with such a unique action and natural pace, which is always in the game on any surface," Root said.
"That with the skill of the others, makes for a tasty combo. One thing it will do is make them (Australia) think about how they're going to have to come back. He is going to come at them, and it's always nice when you're stood at slip and not batting against him.
"He's very different to other options that we've had previously in this team, and on a different surface, which might nibble and swing a little bit more to add that into a quartet, it's a really big bonus for the team. You always feel like you've got something different to turn to," he added.
Ben Stokes, who was the man of the match in the second Test, described Archer's performance as "frightening".
"I am not sure there will be a better debut in terms of announcing yourself. The spell (to Smith on the fourth day) was incredible to watch," Stokes told Test Match Special. "We were laughing he was going to be top of the rankings after one Test. We are very lucky he is in our team. He gives you an extra dimension."
Australia, however, are not panicking yet, despite being made to bat on their toes by the tearaway English pacer.
"We've seen him for a few years now (in T20 cricket) and we know the package he brings with his pace," Australia captain Tim Paine said.
"That's something every team wants to have. It's up to us to make some plans and get better. It's not all doom and gloom," he added.
It is fast and furious, though.
