South Africa continued to live with the tag of chokers in the ICC events as they failed to defend a modest 175 after their top and middle batting order collapsed.
De Villiers said his bowlers tried hard but could not do much as the wicket had probably eased out later on.
"We tried everything with the ball but it got pretty flat in the afternoon. There's no excuses. We had the talent to win this tournament. We just didn't play well enough," de Villiers said after his side lost the semifinal by seven wickets.
"It was the hardest team selection I've had. Alviro would have been great in the team but we backed Hashim and Colin. I'm especially proud of David Miller and Rory, they kept fighting to the end and that's what I expect from our guys," he said.
