An outstanding all-round performance by England produced an astonishingly one-sided final and condemned South Africa to an ignominious defeat.
Solanki completely dispensed with cross-batted shots and played beautifully
Certainly, there will be no happy memories of South Africa's first appearance at Lord's in a one-day international; only serious concerns about the form of their batsmen with the first Test only 10 days away.
It was Darren Gough who set the tone of the day with a tremendous opening spell of 2-9 from seven overs.
He is desperate to prove his fitness for the first Test, and his bowling, both here and at Bristol earlier in the week, suggest that he is in good form - it's just a question of whether or not the selectors dare to gamble on his fitness.
Gough was superbly supported by Chris Read who claimed five catches - a performance which is certain to spark debate about Alec Stewart's future in Test cricket.
James Anderson also took two early wickets as South Africa's innings spectacularly failed to get going.
They were 43-4 in the 12th over, and although Jacques Rudolph and Mark Boucher put on 32 for the fifth wicket, the lower order fell apart in a lacklustre manner which was as curious as it must have been worrying for Eric Simons, South Africa's coach.
To be dismissed in 32 overs in sublime conditions was a pitiful effort.
The most positive aspect of England's reply was the batting of Vikram Solanki.
For the second time in the series he completely dispensed with cross-batted shots and played beautifully.
South Africa urgently need their batsmen to get scores under their belts
This is no coincidence, and a lesson he must take away with him when he returns to Worcester.
He drives with a rare elegance, but he must dispense with the hoiks, which brought about his downfall too often in this tournament.
He made exactly 50 having swept the game away from South Africa in a rush of a partnership of 87 in 14 overs with Michael Vaughan, who scored 30.
England will reflect on the advances made by Solanki, Andrew Flintoff and Read, and the return to form by Marcus Trescothick and Vaughan.
The fielding was outstanding throughout, while Gough's return to the side gives the selectors something to consider.
The South Africans, meanwhile, urgently need their leading batsmen to get some scores under their belts between now and Edgbaston.
