The 2003 NatWest Series was a One Day International cricket tri-series sponsored by the National Westminster Bank that took place in England between 26 June and 12 July 2003.

The teams which finished in the top two positions following the group stages qualified for the final, which England won by defeating South Africa at Lord's on 12 July by 7 wickets.

For many of the South African batsman this was their first time playing on the sloping Lord's pitch, which at the start of their innings had a little moisture in and displayed even bounce.

[3] Jacques Kallis came into the match with a series average of 164.50, but was dismissed for a 12 ball duck by Darren Gough, who was England's most economical bowler, with his opening spell of 7 overs conceding just 9 runs.

[3] England's response started poorly, with Makhaya Ntini dismissing Marcus Trescothick for a nine ball duck with the score on 1.
