South Africa 209-5 Innings Complete (M V Boucher 63 no, G C Smith 50)v England Lions 210-4 (S R Patel 60 no)
England Lions beat South Africa by 6 wkts
England Lions dented South Africa's confidence ahead of next week's one-day series with a crushing six-wicket win in Derby.
An unbroken century stand between Samit Patel and Eoin Morgan steered the Lions to victory with almost nine overs to spare in the tourists' final warm-up match before the NatWest Series.
The Lions were much-changed from the four-wicket defeat to the same opponents on Thursday.
With Rob Key playing in the Friends Provident Trophy final at Lord's, Middlesex's Ed Joyce took over the captaincy. Having won the toss, he was indebted to the useful change bowling of his fellow England one-day international Dimitri Mascarenhas.
The Hampshire captain took the important wickets of Graeme Smith (50) and Jacques Kallis in his two for 26, while Jonathan Trott, another medium-pacer, finished with two for 17.
Nottinghamshire seamer Darren Pattinson broke a first-wicket stand of 67 between Proteas captain Smith and Herschelle Gibbs but the seamer's chances of an England recall were not helped by his figures of one for 62 from only seven overs.
Wicketkeeper Mark Boucher (63no) and Vernon Philander weighed in with an unbroken stand of 111 as the Proteas finished on 209 for five.
Boucher's near run-a-ball effort contained five fours and two sixes, but the recovery he and Middlesex all-rounder Philander managed rarely looked likely to be enough once the hosts got back on track after the early loss of Trott to a run-out.
Handy runs came from Matt Prior and Owais Shah in a second-wicket partnership of 71.
Then after a mini-wobble, Morgan (47no) and Patel (60no) finished the job in style - with 8.5 overs unbowled.
It was a satisfying performance for Nottinghamshire all-rounder Patel in particular - his half-century containing six fours and a six - making up partly at least for a first-ball duck on his debut at this level at Grace Road.
