In progress. On 4th day SA had lead of 381 with about 25 overs remaining, they had 5 wickets in hand and Bavuma was on 78* that is when the captain DeVilliers declared the inning. Very surprising to me. They could have batted few more overs, up the scoring rate and add 18-20 more runs to make the lead 400+.
In 21 overs SA was able to grab 3 top Eng wickets, now Eng at 52/3 at the end of day 4.
