In the five years since England last had a productive opening pair, it always used to be a question of finding the right partner for Alastair Cook. More and more it looks as though England will have to find a partner for Mark Stoneman, who, aside from the glory tour of 2010-11, has been England's most successful opening batsman in Australia since Michael Vaughan in 2002-03.
Confronting a new Kookaburra wielded by Mitchell Starc and Josh Hazlewood, Stoneman has scored more runs than anyone bar the middle order men Dawid Malan and Jonny Bairstow. Even if his average is only 32, it is higher than that of Cook in three of his four Ashes series in Australia, or Michael Carberry in 2013-14, or Andrew Strauss in 2006-07.
Yet Australia's pace attack, and Perth's bounce, have surpassed anything in his experience. "I've not faced an attack before where they have three guys capable of cranking it up to the levels they do," Stoneman said.
"I think that's one of the things they've been able to manage throughout the series — they've always had a guy coming in relatively fresh. The bounce was a lot steeper than I've ever experienced.
"There were balls that I was picking up the length fine but I was perceiving the level of contact to be chest height, which I would happily get in behind and ride, but they just kept climbing and I ended up splicing them in front of my face."
