South African wicketkeeper-batsman AB de Villiers was embarrassed by his team's mistakes in the field today, after Australia dominated the third day of the first test at Centurion on Friday.< b>

Australian opening batsman David Warner was dropped three times on his way to 115. While the last two were difficult chances, the first opportunity was particularly easy.

Warner top edged a short ball from pace-man Vernon Philander, but substitute fielder Dean Elgar, who was on for Dale Steyn, fumbled the chance.

The visitors then piled on the runs, ending the day on 288 for three with a huge lead of 479 with two days left of play.

"It's not an easy outfield to field on," said De Villiers, who scored 91 in the first innings.

"Still, our fielding was way below our standards.

"After lunch, the fielding was certainly one of the factors that made me feel almost embarrassed, and I'm just very disappointed with the way we fielded and bowled at times.

"There was just no intensity, which is not like us."

Despite the match circumstances, the South African number five said with conviction that the Proteas would not just roll over.

"We're in trouble. Australia have dominated for the whole Test so far. There's only one team playing in this Test match at the moment, and that's not us," he added.

"But giving up doesn't exist in the team culture we've built over the last few years."
