Asked to bat first, Mumbai were off to a steady start with Evin Lewis and Suryakumar coming up with an opening partnership of 87 runs off 64 balls. Yadav was the first to depart for 38 while Lewis was out for 60.
Having won three of their last three matches, Mumbai looked like they were going to launch another comeback. However, after skipper Rohit Sharma was dismissed for a golden duck, there was a short lull phase in the game.
Both Buttler and Rahane kept patience and found frequent boundaries to keep the required run rate in check before the former scored his 6th IPL fifty.
With Rohit Sharma promoting himself to No. 3 in the batting order, the MI side looks more settled than before, and the addition of JP Duminy in place of the misfiring Kieron Pollard has been a welcome change, while Ben Cutting has added some muscle in finishing off innings with the bat.
Buttler's unbeaten 94 at the Wankhede on Sunday was much more free-flowing than some of his other recent fifties and cast away any possibilities of a stumble through the middle - the win was achieved with two overs to spare.
Rajasthan Royals Probable XI: Ajinkya Rahane (c), Jos Buttler (wk), Sanju Samson, Ben Stokes, Prashant Chopra/Rahul Tripathi, Stuart Binny, Krishnappa Gowtham, Jofra Archer, Ankit Sharma/Shreyas Gopal, Jaydev Unadkat, Ish Sodhi. "Man of the Match" Buttler (94*) was exceptional right through the night, timing his shots to perfection as he hit the bowlers all around the park. Sadly, Stokes didn't get a chance to have a crack at the Mumbai bowlers as Buttler got the job done. Mumbai Indians limped to 168/6 in 20 overs and Rajasthan Royals overhauled the target in 18 overs.
Mumbai's opponent, Rajasthan will also come with high confidence. having registered two back-to-back wins against Punjab and CSK, thanks to two fantastic knocks of 82 and 95 not out from English wicketkeeper-batsman Jos Buttler. However, the scenario could have been completely different had it not been for some dropped catches. The likes of New Zealander Mitchell McClenaghan (12 wickets) and Hardik (16 wickets) have failed to keep it tight. Hardik Pandya, Jasprit Bumrah and Mayank Markhande were severely punished by the RR batsmen. If early wickets tumble both Hardik at 13/1 and Krunal at 25/1 would be worthy of a half-stakes punt.
