His career has now reached rare air. In this innings alone he passed two of Test cricket’s most aggressive players in Sir Vivian Richards and Virender Sehwag on the all-time Test runs list. He now has the most Test runs of any player with a strike-rate higher than 70.He moved to fifth all-time among Australian Test runscorers, past Michael Clarke and Matthew Hayden, and is only 13 runs short of becoming Australia’s highest-scoring Test opener.There will be the usual caveats from his critics. Zero Test hundreds in England or India. A spectacular record at home, especially against Pakistan. This was his sixth Test hundred against Pakistan and fifth at home, averaging a staggering 88.56 against them overall.David Warner scooped Shaheen Afridi for an outrageous six•Getty ImagesThere is a case that this too might have been against one of the weakest Test attacks he has ever faced. But while there were times when the bowling looked generous as he and Usman Khawaja rollicked along at more than five-an-over during a century stand inside the first 20 overs of the day, the individual returns of Khawaja, Marnus Labuschagne, Steven Smith and Travis Head on a surface that had bounce and sideways movement suggested it may not have been as easy as he made it appear.Warner profited by carrying on the intent he showed in the ODI World Cup. There have been few players in the history of the game that have transitioned so easily between the three formats and been so prolific too.There has been an element of uncharacteristic timidness in Warner’s Test batting over the last few years. The dynamism and fearless ball-striking he had once shown had disappeared as he struggled to find the balance between defence and attack. But much like his drought-breaking double century against South Africa last year, which appeared in isolation, Warner’s trademark intent was a feature of his play in Perth.He survived an early scare, squared up by a beauty from Shaheen Shah Afridi only for the edge to fly safely over the cordon.He then took guard outside his crease and began shuffling towards the pedestrian medium-pace offerings from the other end and scored at will. If it wasn’t a half-volley crunched for four through cover, it was a push to a gap for one, just as he would in an ODI. Anything short was latched onto. His worries against the short ball on the Test tour of India earlier this year were nowhere to be seen.He lashed two pull shots off Afridi with authority forward of square. Then he produced the shot of the day, a replica of his shot of the year.Just like he had against Haris Rauf in Bengaluru, he made a mockery of an excellent 140.5kph delivery from Afridi. Angled into the top of off on a good length, Warner collapsed his back leg and moved low to the offside to get underneath it and flick it 88 metres over fine leg for six as he rolled onto his back after making contact. The bravery, the skill, and the execution were astonishing. It’s one thing to do it in an ODI on a batting paradise in Bengaluru. It’s quite another in the first session of a Test match on one of the fastest pitches in the world.That he was able to switch gears after lunch when Pakistan improved their lengths speaks to his match awareness. His second 50 took 84 balls, twice as long as his first. But he was patient and diligent, adapting to what was in front of him as he has done so often in the second half of his career.His first 104 were chanceless. He did offer two lives thereafter. A miscued chip to wide long-on went through the meek hands of Khurram Shahzad. Sarfaraz Ahmed later missed a relatively simple stumping off Agha Salman, to rub salt into the wound of the offspinner who had already been thumped for six twice.Warner flicked another bouncer for six before falling by the sword trying to go again, toeing one to a catcher at deep backward square.After Warner had silenced his critics, he received a standing ovation as he left the field. No one can begrudge him his Test farewell in Sydney now.
