South African captain Faf du Plessis says outsmarting Australia and David Warner with a sudden declaration was down to luck.
Du Plessis' shrewd move prevented Warner from opening the batting in Australia's innings late on Thursday's opening day of the third Test in Adelaide.
The Proteas skipper was 118 not out, and his side 9-259, when he chanced upon a conversation between umpires and Warner.
The Australian batsman had just returned to the field after a stint off for a period of time getting treatment on an injured shoulder.
Under cricket's rules, a player must be on the field for the same time they spent off it before being able to bowl or bat again - in Warner's case, he was caught short.
"
I listened to the conversation he had with the umpires - one ear talking to the batter, one ear listening to him," du Plessis told reporters.
"
And then I heard he had six minutes left before he could bat again so I thought 'let's have a crack'."
