He leads that every day.
"I thought they were unlucky in some ways, especially early on, when there were balls that beat the outside edge very consistently", said Bairstow.
While transformation guidelines would surely aid South Africa in the future with more hidden gems being unearthed, the process has to take root at grass level before such stringent policies are kept in national level teams. But Duminy isn't and unfortunately, he is largely responsible for South Africa's soft belly.
As Strauss and Cook could tell you, one of the most challenging aspects of captaining this team is to persuade two brilliant but occasionally stubborn new-ball bowlers to adjust their lengths to suit the conditions. "He adds a lot of value".
The day started well for South Africa as England, who resumed on 119 for one in their second innings, lost seven wickets before lunch in a dramatic collapse. With Moeen Ali now considered a "batsman who bowls a bit" and Liam Dawson in the side as the main spinner, they appear a balanced side.
There was a brief pause before Ali transformed South Africa's 61 for four into 82 for eight. Though Morne Morkel, Vernon Philander and Kagiso Rabada were successful with wickets, they could not restrict the hosts from scoring runs in bulk. Yet one performance is all it took for all of South Africa's familiar woes to resurface.
Asked if the England bowlers bowled too short: "I don't think so".
No man has taken more wickets on this ground than Anderson. "He's a senior player, he knows what he's doing".
Morning cloud cover meant that deciding to bat first after winning the toss was "a tricky decision" according to returning captain Faf du Plessis. He is certain to get chance later in the series and throughout a busy home summer.
South Africa had been 179 for two at tea, but they soon slumped to 235 for six.
"Targets are through a season".
"We want to set the tone with whatever we do on the first morning and drive that through the rest of the game". "It's just about knowing we can do it and going into this next game and doing it". "You can't plan for that".
Anderson is back in the mix after an injury break following a poor tour of India late a year ago. Since readmission, de Villiers is the only other South Africa wicketkeeper to bat at that position.
"Sometimes the peace and quiet is on the field and when you are batting". Pakistan also won twice in London last summer.
Jonny Bairstow has shown fine form with the gloves at the start of the series with South Africa, putting this down to the break from keeping wicket while part of the England one-day set-up rather than any additional hard work in training. Perhaps they will have to wait for next summer to find their answers.
