Player of the day: Jacques Kallis
He also revealed that Paul Collingwood was to participate after his finger injury, meaning an unchanged England eleven took to the field.
I take it back about South African politics dominating their team selection as they saw sense in picking Friedel de Wet ahead of Makhaya Ntini.
By his own admission opening the batting is not Ashwell Prince's preferred position, and that showed through when he went for a duck off just the fourth ball of the match after a terrific Jimmy Anderson outswinger which leaped up off the pitch was nicked off the glove of an unconfident looking Prince and was caught behind by Matt Prior.
It could, and should have been two quick early morning wickets just three balls later when South Africa captain Graeme Smith played at a Graham Onions ball way wide of his off stump, get a nick of the bat and carry at a perfect height to Graeme Swann at slip who completely fluffed it.
Smith's luck continued when a Stuart Broad inswinging ball darted back and straight through inbetween the batsman's bat and pad, inches away from the stumps.
In the eleventh over we had the first review of the game after a Stuart Broad outswinger supposedly edged Hashim Amla's bat. However the video replays failed to show any noticable movement in the ball and it was adjudged not out.
Amla was sent packing for 14 in the sixteenth over by Graham Onions who bowled a well pitched delivery on the line of off stump with a good length, which shaped in towards Amla's planted pad in front of the middle stump, meaning the man SA would want in a time of need - Jacques Kallis came to the crease, and boy would they need him!
A pearler from Jimmy Anderson just after lunch was enough to dismiss the South African captain Smith, as the ball pitched around middle and off stump moved away off the seam and caught an edge of Smith's bat, caught behind by a terrific Prior dive in front of first slip. South Africa were 51-3 and AB de Villers and Jacques Kallis set about rescuing the solution.
Surviving a few dangerous deliveries to start with, de Villiers and Kallis settled in and began to repair the damage. AB de Villers was the first to go of the pair, with a silly lapse of concentration on 36 when he chipped the ball up to Andrew Strauss off a Graeme Swann delivery.
South Africa were then really on the back foot when JP Duminy recorded his second golden duck on the bounce when Graeme Swann's off spinning delivery bowled from around the wicket to the left hander turned sharply away and caught a nick of the bat, and was snapped up by Matt Prior leaving SA 127-5.
Shortly after Boucher arrived Kallis made his 53rd test 50. Boucher joined him later on in the innings after an impressive knock, before he went for LBW by Broad after the ball hit the back pad in an impressive delivery. Boucher challenged the decision only for replays to show that the ball was destined for the top of middle.
Kallis continued in his cool, calm and collected manner frustrating the England attack before bad light caused a premature ending to the game. At the close of play Kallis was on 108* alongside Dale Steyn on 26*, leaving SA 279/6.
It has been a day where both sides will feel they could have done better, leaving the test still very wide open. I would say England have the slight edge, however to keep it that way, Jacques Kallis will be a must-take wicket as soon as possible for England tomorrow.
