There were concerns about the weather before the second T20 but instead of the anticipated precipitation, it was raining boundaries in Manchester.
Salt, who was dismissed for a golden duck in Cardiff on Wednesday, set the tone for the evening with 18 runs off the first over, including three consecutive fours to start the innings, but was largely a passenger for the first seven overs as Buttler took charge.
The former captain smashed six fours and four sixes en route to an 18-ball half-century inside five overs and treated every South Africa bowler with equal disdain, pouncing on anything short and scoring for fun over mid-off to drive England to 100-0 at the end of the powerplay.
He rather gave away his wicket as a century beckoned, caught sweeping by Tristan Stubbs, but it did nothing to halt England’s momentum, with Salt seizing his opportunity to steal the show.
In the eighth over, he dispatched Lizaad Williams for two fours and two sixes to bring up a half-century of his own off 19 balls before hitting a further four fours off Kwena Maphaka as England reached a record 166-1 at the halfway mark.
He ran two off Kagiso Rabada to seal his record-breaking century in 13th over, struck a further seven boundaries during the second half of his innings, and enjoyed stands of 95 off 41 and an unbroken 83 not out off 37 with Bethell and Brook, respectively, as England refused to take their foot off the gas.
It was, admittedly, a below-par bowling performance from South Africa. Four of their six bowlers conceded more than 15 runs per over and Rabada was responsible for four of his side’s no-balls.
Their desperation was clear when captain Markram brought himself on to bowl the 12th over and was struck for 19.
But as poor as South Africa were, Salt was simply superb, playing a mature and chanceless innings, toying with the field in between his bludgeoned sixes and scoring all around the ground.
