Quinton de Kock has called time on his South Africa career in the two longer formats.

What happened?

He retired from Tests in the middle of a home series against India two Decembers ago.

Why it matters for Quinton de Kock

His ODI career ended after the World Cup, which for South Africa finished at Eden Gardens on November 16 when they lost their semifinal to champions-in-waiting Australia.

Quinton de Kock doesn't take long to make up his mind, or he has an interesting sense of timing.

What comes next?

He will play T20Is against India at Kingsmead, St George's Park, and the Wanderers on December 10, 12, and 14.

These matches could be his last at this level before he moves on to franchise leagues.

Quinton de Kock is in control of his destiny as a player because he isn't reliant on the international game to pay his bills.

He isn't afraid to make bold decisions about his way forward, and he doesn't give much warning about his change of plan.

Cricbuzz tried to glean an informed inkling about how long De Kock will keep playing for South Africa.

None of the answers took them closer to the truth, with one view suggesting he lives in his own world and didn't know himself when he would pull the plug.

Another view was that he and CSA would have to plot a careful path to keep him in the mix at all.

Quinton de Kock seems as fully focused on hitting or catching a ball as is humanly possible, with nothing else appearing to matter when he is in cricket mode.

His fans will be watching him closely in the upcoming T20Is to see if they will be his last at this level.

The start of the T20 World Cup is just over six months away, which may influence his decision.

Quinton de Kock's international career has been marked by his elegant play on the field.

He evokes a penguin on ice in the bigger scheme of things, with all elegance on both sides of the popping crease.

The sadness over De Kock's approaching exit from the international stage should be distinct from his missteps in navigating the politics of sport in South Africa.
