England responded to their Champions Trophy disappointment with a nine-wicket win against South Africa in the first of three Twenty20 internationals.
England were excellent with the ball in Southampton, restricting the Proteas to 142-3 despite a stand of 110 between AB de Villiers and Farhaan Behardien.
Jonny Bairstow made 60 not out off 35 balls and Alex Hales an unbeaten 47 to complete the chase with 5.3 overs left.
The second match of the series is in Taunton on Friday.
Victory would give England a series win to follow a 2-1 success in the one-day internationals that came before the Champions Trophy, where they were beaten in the semi-finals by Pakistan.
Four Tests against South Africa follow the T20s.
