Netherlands stunned South Africa by 38 runs in the ICC World Cup's second big upset in three days in Dharamsala on Tuesday.
Netherlands scored 245 for eight after South Africa opted to bowl in the rain-hit match. In reply, South Africa were all out for 207 in 42.5 overs.
The game began late owing to inclement weather, and was reduced to a 43-over-a-side contest.
When their turn to bat came, the Proteas were off to a decent start before losing four wickets in a heap to be reeling at 44 for four in the 12th over.
The South Africans could not recover from there as the Dutch bowlers shared the spoils between them to script one of the World Cup's biggest upsets.
On Sunday, Afghanistan humbled defending champions England by 69 runs for this tournament's first shocker of a result.
