5.20pm So that's the end of an absorbing series. Thanks for all your comments and feedback, and don't forget to tune in next week for the start of the ODI and T20 series. Eoin Morgan's men have arrived in the country, and the switch to coloured clothing begins in no time at all. Valkerie is bashing out her match report, and George and Firdose are primed to bring you all the post-series reaction. From all of us here, thanks and goodnight!
AussieBren: "I can't wait to see Mark Wood in action here in Australia. Our pitches will definitely suit his bowling and express pace. The Ashes are looking juicy!"
5.19pm Root accepts the Basil D'Oliveira Trophy, and the rest of the squad rock up for some champagne-popping and photo-posing. It's been a hell of a fightback after that cursed start to the campaign in Benoni and Centurion.
And finally, here's Joe Root. "To pick ourselves up and play as we have is very pleasing. The guys have taken their opportunities, and the sky is the limit for us right now. It's been a fantastic tour for our development as a Test team. It's very exciting, plus guys like Jofra and Dom Bess, a real squad effort from guys at the start of their careers. It's a fantastic place to come and tour, we always expect a fierce rivalry and it didn't disappoint."
The Man of the Series is Ben Stokes. Again, not entirely unsurprisingly. "The ost important thing is we are walking away with a series win, I hope the old man is in his hospital bed with a big smile on his face. I think it's always such a competitive series, good pace in the attacks, the wickets have a lot in for bowling and batting. I love the competition that South Africa brings."
"Everyone's stood up and made contributions, a massive team effort and I'm really proud of everyone in the dressing room."
The Man of the Match, fittingly, is Mark Wood. A huge cheer from the Barmy Army as he receives his trophy,
"There was a bit of doubt going in but boy am I glad I played now. I'm over the moon. I've had a lot of dark days, credit to the back-room staff, everyone's so supportive, Chris Silverwood tries to get me to have fun. I give it everything I've got, run in hard for the captain, as much energy as I can, and let it fly."
Faf du Plessis: "Right through this series after that first game, England were better in every department than us. Anrich Nortje came through shining for us, we need pace to take the place of Steyn and Morkel, it's impressed me most, the skill to land the ball in the same area. Beuran came in with five in his first Test match. We didn't put enough runs on the board, though Rassie played well today and was unlucky not to get a great hundred.
"I'd like to thank Vern for his services to the Proteas over the years, this team will miss him so, so much. We will sit with him tonight in the dressing room and share in the memories. It's a lot of effort and time, the sacrifices you make over ten years."
5.07pm Vernon Philander is presented with a token for his final Test. A #BigVern montage... how nice. "I think we fight hard on the park but remain gentlemen at the end of the day. It's been an honour and privilege to share a dressing room with so many greats.
"I think now the hard work starts, giving back to young talent is my mission in life, to mentor a couple to play in this wonderful team one day."
5.04pm Out come the players for the presentations. Wood is grinning like the Cheshire Cat's northern cousin. He's a clear candidate for man of the match.
adam: "Miller, will Wood play in SL? I really hope not. Give him a rest, for goodness" He'll be there. He's missed enough cricket as it is!
5.03pm Stephen Procter: "9 wickets in the match, plus 50 runs at better than a run-a-ball... MA Wood is in rarified company indeed". Crumbs. All hail the next great allrounder!
4.58pm Sooryanarayanan: "If only fairy tale endings existed for all. You are a champion nonetheless Big Vern. A real fighter who didn't let his limitations with pace stop him from stamping his authority as a world-class bowler. Well played and wish you the very best for your new innings. " Too true. A sad ending, as he heads off into the Somerset (seeing as Roller's stealing my jokes, I'll steal other people's!) but what a contribution he has made.
Daniel: "Bowlers like Mark Wood are the difference between winning and losing in places like Australia and India. Got to manage him well and hope his injuries are behind him, his spells here and in the WI are what Eng need if we're progress to the top level"
Ben: "England now have the best away win ratio of the top test teams over the last two years. Home record is fifth over the same time period. Long way to putting to bed those away myths?" How curious! It's progress of sorts...
4.52pm Handshakes all round outside the pavilion, even a hint of a hug from Buttler and Philander, who have been chirping away at each other throughout a feistily contested series.
ADB: "Robbed! Wood, I mean, by that run-out." True that ... that was a nailed-on ten-for, given that none of the tail seemed entirely keen on getting in line to his bombs. What a breakthrough it's been for him. Fit and fast, and a key cog in this rising England team. Far from the finished article, and consecutive winters in India and Australia will test their mettle to a far greater extent. But there is no such thing as an easy series win against South Africa, and this one is no exception.
adam: "Wood's record away from home is insanely good now" ... you're not wrong. That's what England have lacked overseas in recent years
Ag: "Someone in the commentary team mentioned at the start of the day that the SA resistance will last an hour after tea ......I should use his tips for making my fantasy league teams...." Never in doubt.
4.51pm Well, that was emphatic in the final analysis. South Africa fought hard in the first half of the day, but once Rassie van der Dussen and Faf du Plessis fell in quick succession, the rest were rounded up with disheartening haste. Very professional and emphatic from England, but South Africa have so many issues to address as they reflect on a 3-1 series loss, and their first back-to-back home series defeat since the 1950s...
And that'll be drinks. Here's Miller to talk you through the last rites. And don't tell him I stole his Shamen joke...
Root sprinting through this over, Jadeja-style
Michael Muller: "May as well declare so they can get in a round of golf tomorrow morning." De Kock's shot was that of a man with a 9am tee time for tomorrow!
Hendricks looks a million dollars between balls, top button done up, chewing gum like he's Sir Viv. Slightly less convincing when he has to hit the thing, though
"And it's all over bar the shouting," Cassim declares. "Last rites being read"
Cal: "AB de Nortje pulling out a reverse sweep. Beware England, he is in the mood" Needs to unleash the beast from here...
