England skittled out South Africa for 83 to win the rain-affected second one-day international by 118 runs on Friday and send their three-match series to a decider.
The start of the match at Old Trafford was delayed for almost four hours, meaning it was reduced to 29 overs per side and England scrambled to post a total of 201 after being put into bat.
A strong bowling performance immediately put South Africa on the back foot, with the tourists reduced to 6-4 after four overs as Janneman Malan, Rassie van der Dussen and Aiden Markram were all out for ducks.
