Quinton de Kock's sensational century propelled South Africa to a remarkable six-wicket victory over West Indies in a thrilling T20I after a record-breaking knock from Johnson Charles at Centurion.

Charles' astonishing 118 from 46 balls and an excellent 51 from Kyle Mayers got the Windies to what looked to be a series-winning total of 258-5 on Sunday.

Yet De Kock (100 off 44) had other ideas, with South Africa's former captain leading the Proteas to a sensational triumph and the highest successful run chase in T20Is.

By the end of the third over the hosts had scored 62 without loss, and they added an additional 20 runs from the next 18 deliveries. South Africa's total of 102-0 from the first six overs is the highest powerplay score in a T20I involving Test-playing nations, and the fastest first hundred runs scored in a T20I involving a full ICC member.

In the process, De Kock struck South Africa's quickest 50, from just 15 balls – the fifth-fastest half-century in the shortest format.

De Kock should have been caught in the deep shortly after, but did not let up as he cruised to his maiden T20I century, taking just 42 deliveries to get there, before falling to Raymon Reifer soon after.

Reeza Hendricks (68 from 28 balls) picked up the slack, though he followed Rilee Rossouw (16) in heading back to the pavilion when the Windies claimed wickets in swift succession in the 12th and 13th overs.

Romario Shepherd caught David Miller to hand West Indies a further flash of hope, yet three big hits from new captain Aiden Markram (38) put the Proteas back in control as they cantered to victory and levelled the series.

Charles' record ton overshadowed

If it was not for De Kock's sparkling knock, Charles would have been the story.

His century, which came from 39 deliveries and included 11 sixes and 10 fours, was the fastest T20I hundred by a West Indies player, surpassing a record set by Chris Gayle in 2016 (47 balls). Unfortunately for the tourists, it was not enough.

Bad day for the bowlers

It was certainly a day for the batters at SuperSport Park. South Africa's bowlers set the tone for what was to come as they struggled to keep the Windies under wraps, despite Wayne Parnell (2-42) dismissing Brandon King in the first over.

The Windies attack then suffered as De Kock, Hendricks and then Markram put them to the sword in a stunning display.
