The Royals had previously been defeated on three occasions by the neighbours from Cape Town, with the latest reversal having been Friday evening at Newlands.
The first double-header of season two provided run-fests at both the Wanderers and St. George's Park, with an aggregate of 803 runs scored across the four innings.
It had been tough going for the Sunrisers leading up to their clash with MI Cape Town at St George's Park on Monday evening as they were the only team yet to win a game in this year's competition.
Morgan and Buttler, along with fellow 2019 World Cup winner Jason Roy, will be reunited at the Paarl Royals next month for the inaugural SA20 season, and it's this vast championship-winning experience that coach JP Duminy can rely on at Boland Park.
