‘Frightening’ Archer has

Joe Root believes Jofra Archer has changed the dynamic of the Ashes series after a ‘‘frightening’’ test debut at Lord’s.

Archer bowled 44 overs, struck Australian players 11 times and left Steve Smith, the finest batsman of his generation, fighting to be fit for the third test with a concussion injury.

After years of England batsmen being on the receiving end of bouncers from Australian fast bowlers, Root is relishing unleashing Archer and believes he can lift his side to win two of the last three tests and regain the Ashes

‘‘He has come in and had a massive impact and added a dynamic to our bowling group. He has given Australia something to think about and it is really impressive to see someone come in on test debut and shake up things and live up to the hype. It makes for some very interesting last few games,’’ Root said.

‘‘He makes things happen when not many others in the world of cricket can.

‘‘He has such a unique action and way of bowling, and his natural pace is always going to be in the game on any surface. With the other guys around him, it makes a tasty combination, which is why we always felt we were in the game.

‘‘They will have to think quite clearly how to combat how he is going to come at them. It is different to the other options we have had previously in this team. On a surface that might nibble and to add him into a quartet is a really big bonus for us.’’

Root admitted England were shocked to see Smith walk out to resume his innings on Saturday after his sickening blow on the neck from Archer. ‘‘It was a horrible moment. You are always trying to find different ways to get guys like Steve out, but you don’t want to see that. I couldn’t believe he came back out, but he was desperate to do well for Australia and his team-mates.’’

Ben Stokes was named man of the match for his unbeaten 115 in England’s second innings of 258-5 declared, but he also paid tribute

to Archer after the second test ended in a draw with Australia 154-6 chasing 267.

Stokes fielded close in to Archer for most of the two Australian innings and was blown away by his impact.

‘‘Frightening. I am not sure there will be a better debut in terms of announcing yourself in the team,’’ Stokes said.

‘‘The spell [to Smith] was incredible to watch, 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.’’

Tim Paine, the Australia captain, was one of Archer’s three second-innings wickets and was clearly unsettled by his bouncers. He admitted Australia would spend the next few days discussing how to face Archer.

‘‘We have seen him for a few years now. We know the package he brings with his pace and that’s
