Du Plessis: Boos would have driven me to bat all week

Faf du Plessis criticised Australian fans jeering his outstanding century after a day of redemption in the Adelaide Test for South Africa's captain.

Du Plessis crafted a brilliant 118 not out, partly under the lights, at the Adelaide Oval, forming the bulk of the Proteas' 259-9 declared.

Able to play, despite being charged with ball-tampering in the second Test, Du Plessis was booed onto the field with his side struggling on 44-3. His fifty and hundred were also met with a negative reaction, although the latter was also widely applauded.

Saying that his determination to respond to a tough build-up meant he could have batted "for another week", Du Plessis also called for more decorum from the home support.

"I was expecting a little bit of hostility but not to that extent," Du Plessis said. 

"When I came out I was quite aware of it. As the innings went on it disappeared a bit.

"But to be really honest with you guys when I got to hundred, I wasn't expecting to still get booed, so that was pretty disappointing.

"[I'm] just really proud of today. It was a big day for me to stand up as a captain and make sure I led from the front. To get through all of that and this week in the manner I did today makes me really proud of the performance.

"I was really motivated before today. I felt it was a character test and the only way I could do it was by scoring runs. It [the booing] did help a little bit.

"Every ball today, I've never been that switched on to say to myself 'it's not enough, I want to get a big one here'. I was more motivated than I've ever been.

"The way I felt mentally I could have gone for another week."

With Australia opener David Warner suffering a shoulder injury, Du Plessis' unconventional declaration raised eyebrows and he admitted he had found it challenging to bring his fantastic knock to an end.

"I was so driven but the position of the game it was time to declare," he explained. "There was a lot of talk about the pink ball at night so it was a great opportunity to try and at least make a positive move."
