Cape Town - South Africa captain Faf du Plessis said the Proteas had only themselves to blame for their early exit from the World Twenty20, and rued mistakes at key moments in an otherwise decent tournament.
The Proteas failed to reach the knock-out stage after defeats to England and the West Indies, both of which were tight affairs. Against England, the bowlers failed to defend 229 runs, while against the Windies the batsmen posted too small a total.
Their final match was a win against Sri Lanka, which was anti-climactic as both sides were already out of the running.
The Proteas chased down 121 to win with ease against the 2014 champions.
Du Plessis said: "We played good cricket leading up to the tournament and we were consistent in the subcontinent, but a World T20 is a do-or-die tournament.
"If you make mistakes, it's not like a series where you can come back into the series. We made one or two mistakes against England and they punished us for it. Against West Indies, we made one or two mistakes as well.
"The teams in a T20 world cup are so close to each other, if you're not on top of your game, teams will punish you.
"We've had signs of playing really good cricket through this tournament. The England game was as good a batting performance as you will see, but obviously not a great bowling performance.
"Same thing with West Indies - we didn't bat as well as we wanted to, although, on that wicket, 10 more runs would have been par. In both games we did one half of the game really well.
With the tournament format changing from every two years to every four, the next even is in 2020, and Du Plessis is sad for the likes of Dale Steyn, and even AB de Villiers, who may not get another chance to win this title.
He added: "The sad thing is that it's now four years to the next World Cup - it's not just two. A few players here won't be there then.
"That's going to be the challenge now for the squad: to try and rest some of the senior players, to see if they want to go to the next World T20. With that you can breed some young players.
"There's not a lot of T20 cricket coming up this year, so it will probably take a backseat."
