With the tourists at 146-3 and having endured a tough examination from Australia's bowling attack, Pietersen swatted a Peter Siddle delivery to Mitchell Johnson at mid-on who took the catch, but Carberry refused to criticise his teammate's shot selection.
Carberry told reporters: "It's a shot that many of us have seen him play time and time again and hit it out of the ground.
"We want people to play how they play naturally. I wouldn't want to see Kevin put that shot in the locker."
Peter Siddle has now dismissed Pietersen ten times in Ashes Tests.
