England captain Alastair Cook paid tribute to James Anderson and James Tredwell for destroying South Africa's batting in a one-sided ICC Champions Trophy semi-final.
Anderson made full use of the humid conditions at The Oval with a high-quality spell of swing bowling and picked up 2-14 before James Tredwell, filling in for Graeme Swann kept England on top with figures of 3-19.
A late-order fightback dragged South Africa from 80-8 to 175 all out, but it was not enough to prevent England from cruising into the final by seven wickets.
Jonathan Trott anchored England's chase after the Alastair Cook and Ian Bell fell cheaply, making a composed, unbeaten 82 and putting on 105 for the third wicket with Joe Root (48).
Cook said of Anderson: "It was a lot more humid today and swung in the nets on Tuesday. It hasn't swung conventionally but when it does, he's the best in the world.
"It was a good toss to win and Jimmy was outstanding - seven overs, two for 14 - and 'Tricky Tredders' was outstanding again."
Cook also picked out wicketkeeper Jos Buttler, who took six catches, as he summed up an impressive team effort.
He added: "To win a tournament you need everyone contributing at certain times and we've done that in this tournament. Trott played a great innings to see us home, Jos with some great keeping and Tredders is so reliable.
"It's been a good tournament so far, the support's been great with the home crowds and hopefully that will be the same on Sunday."
Man-of-the-match Tredwell said: "When you get two wickets in the first four or five overs, you're up and running. If when I come on, they're three or four down, it's easier."
Trott has repeatedly come under fire for scoring too slowly in one-day internationals, but he said: "People get caught up in stats, strike rates and so on, but I just think if you look at the end of the tournament and you've won, then you're doing the job.
"I'll look back on my career in terms of the trophies I've won. Your personal achievements are nice to have but if I can play in a winning team then I'm happy."
