That is about as convincing as one-day victories come and it has been an outstanding all-round display from England - barring a few dropped catches. Paul Collingwood is the man of the moment with his unbeaten 105 to go alongside a great catch and two wickets. Any votes for Man of the Match? But a word, too, for Jonathan Trott who was also superb.
South Africa have some thinking to do. There side looks a little unbalanced without Jacques Kallis and is a strike bowler short to support Dale Steyn. Roelof van der Merwe had a poor day and generally the home side were a fair way off their game. They have five days to turn things around before the next match in Cape Town on Friday. Stay with us, I will bring you the presentation details shortly.
Graeme Smith. "Credit to England, they bowled well and we were 30 runs short. I think we were a little soft with a few dismissals in the middle. I'd like to congratulate Paul Collingwood...It's going to be a tough summer and we will have to be at out best."
The Man of the Match is...[suspense]...Paul Collingwood. "It was a big day for me, but I thought the team were fantastic all the way through. I had a bad back last week but the medical staff did a great job and hopefully I'll be fine now."
Now Andrew Strauss's turn: "The toss was important, but I was very happy with how we bowled. It was a professional performance. Paul and Jonathan played very well and hopefully we can take this forward. We aren't going to get carried away, but are fairly happy with where we are at the moment."
That just about wraps it up for today, England can be mighty pleased with their effort. We will be back on Friday for the third match, a day-night game starting at 2.30pm (12.30GMT). For now, though, it's goodbye from Andrew McGlashan and Sahil Dutta.
