South Africa bowler Anrich Nortje celebrates after dismissing Ben Stokes who walks off the field during Day Two of the First Test match between England and South Africa at SuperSport Park on December 27, 2019 in Pretoria, South Africa
South Africa bowled England out for 181 in their first innings and had built up a significant 175-run lead by the close of play on the second day of the first test at Centurion Park on Friday
But a see-saw contest was still in the balance as the hosts were precariously placed on 72 for four in their second innings as England sought to bowl themselves back into contention.
Rassie van der Dussen (17) and nightwatchman Anrich Nortje (4) will resume on Saturday with South Africa looking to take the contest away from the tourists, who need early wickets to keep alive hopes of engineering an exciting comeback.
South Africa started the day on 277-9 and were quickly out as they added just seven runs for a first innings total of 284.
England lost two wickets before lunch as they began their reply amid a torrid spell of bowling and then saw captain Joe Root dismissed at the start of the second session.
However, they began to settle in when Joe Denly and Ben Stokes put together a 72-run partnership for the fourth wicket.
Denly, who was dropped in the slips before scoring and took 28 balls to get off the mark, made 50 off 108 before falling to the tiniest tickle as Dwaine Pretorius grabbed a maiden test wicket but only after South Africa had asked for a review.
That set off an England collapse as their last seven wickets tumbled for 39 runs with Vernon Philander taking 4-16 from 14.2 overs and Kagiso Radaba bagging 3-68.
"It was tough, a very impressive spell from Philander and Rabada, who challenged us in good areas," said Denly.
The initial breakthrough for the home attack had come from the tandem of South Africa’s new pacemen Nortje and Pretorius, who grabbed three wickets between them in the space of 17 balls to initiate England's disintegration.
It included Stokes caught behind for 35 in a South African record-equalling six catches for wicketkeeper Quinton de Kock.
England quickly began their fightback as veteran James Anderson had Aiden Markram trapped leg before wicket with the fifth ball of South Africa's second innings.
The wickets of Zubayr Hamza and Dean Elgar soon followed and English hopes were boosted further when home captain Faf du Plessis departed for 20 after pulling a hook shot, played from one knee, to long leg where Sam Curran made a running catch.
"We have to keep up aggression and get the ball old as well when we bat tomorrow," said Philander.
