Very bad performance from the Lankan team everyone was not expecting this kind of Performance which shows zero resilience against the peace attack of South Africa. This is not what you have to do on the World Cup stage where everyone is seeing you especially your country people just look at the USA the way they played indeed it's against CA but it's still a team and the pressure of the World Cup and the USA Playing it for 1st time but they performed brilliantly well.
You are right, Sri Lanka batted so badly that it looked like Sri Lanka had come to pass the time, not to play the ICC World Cup. And if we talk about the head to head comparison of the two teams , here both the teams have been sitting in the ups 17 times out of which south Africa have won 12 times , while Sri Lanka have won the matches only five times and behind them in the last five Matches . South Africa have won 5 matches and Sri Lanka have not won a single match . So in this sense South Africa side is looking heavy and in this match they have proved that South Africa is heavy on the Sri Lanka team by winning this match .
