South Africa all-rounder Dwaine Pretorius believes England are around 70 runs short of a par total after collapsing on day one of the second Test at Newlands.
The tourists, trailing the four-match series 1-0, slumped from 185-4 to 234-9 in the final session before Ollie Pope took them on to 262-9 at stumps with an unbeaten 56.
Ben Stokes (47) was among the England batsman who get themselves in but failed to go on after Joe Root had won the toss.
Pretorius, who took 2-26, thinks the Proteas are ahead of the game after reaping the rewards for some disciplined bowling.
"It is very important to take wickets before the new ball. Because it makes the tail shorter and I am glad to contribute," said the 30-year-old.
"They had a lot of guys that got in today and then got out at the wrong times.
"I have not played much Test cricket but a par score would be about 350. So, I think they are about 70 runs short."
He added: "It was hard work getting wickets today but our discipline allowed us to get wickets at crucial times."
Vernon Philander, Kagiso Rabada and Anrich Nortje also chipped in with two wickets apiece as England's frailties were exposed yet again.
