David Miller made the difference as he blasted an unbeaten 75 for South Africa to win the T20 series by beating Ireland by 42 runs.
David Miller said he was not expecting to play but he was always ready for his chance after playing just one game for the franchise last season.
The Royals were 17 for 3 in the fourth over and 42 for 5 at the halfway mark. They needed 58 from the last five overs and 12 from the final over.
Rajasthan Royals will play their first match on April 12 against Punjab Kings.
Dismissing de Villiers and David Miller with their brilliant fielding, Team India enjoyed a huge boost in confidence.
