Riding on a fine bowling performance by Kevon Cooper (4 for 18) and resolute unbeaten half-centuries by Ajinkya Rahane (62) and Sanju Samson (50), Rajasthan continued their unbeaten run in the tournament.
The hosts didn't put a foot wrong as they first bundled out the visitors for a modest 120 in their stipulated 20 overs and then returned to overhaul the target with consumate ease, reaching 121 for one in just 16.3 overs.
Mumbai Indians too are in the reckoning with six points from as many matches.
Chasing a victory target of 121 runs, Rajasthan lost their skipper Rahul Dravid (2) in first over but Rahane and Sanju didn't allow the it to affect their chase and kept them well in the hunt.
The duo added 120 runs for the second wicket, sharing 11 boundaries and four sixes between them in 95 balls at the Sawai Man Singh stadium here.
