However, having bowled 44 overs at Lord's and a further 31.1 at Headingley, Archer's speeds were noticeably down in his 27-over spell at Old Trafford, averaging in the mid-80s compared to the early 90s, a point which Justin Langer, Australia's coach, had flagged before his debut when he vowed to
"keep wearing him down" as the series wore on.
Archer's approach to the crease was shown by Sky's analysts to be slower too, a point which Silverwood acknowledged.
"The one thing that we see, sat on the side when he's running in, he gets his knees pumping and he really attacks the crease," Silverwood said. "But again, it's part of his learning process, he is figuring out what he can and can't do in Test cricket at the moment. And it's his third game. "The exciting thing is we know he can hit 90-plus miles an hour but, saying that, I didn't bowl fast every day either, even though I tried. Sometimes it just doesn't click."
Archer also appeared non-plussed at one late stage of the innings, when directed by his captain Joe Root to bowl round the wicket to Tim Paine - a tactic that lasted for two balls before he reverted to his standard angle from over the wicket. Root's captaincy of Archer has raised eyebrows all series long, amid concerns that he is over-using his most potent weapon, and expecting him to fulfil too many roles in the attack.
