Sent in to bat, MI had lost half their side within the first 10 overs, results of either rash shots or poor running between the wickets.
The hosts then recovered somewhat through a belligerent knock of 33 off just 22 balls with five fours and a six from skipper Harbhajan Singh, but the final tally looked well below par for the course.
It was also their second-lowest in IPL history, a shade better than the 87 all out against Kings XI Punjab last year at Mohali.
In the top order, only Rohit Sharma contributed with a chancy 29 in 27 balls with five fours while the others fell for single digit scores, including last match's man of the match Kieron Pollard who was out for a 3-ball 1.
For the Daredevils, who came here after hammering last year's winners Chennai Super Kings at home, the wickets were shared by their impressive bowling attack.
Left-arm spinner Shabaz Nadeem struck two blows in his first two overs to draw early blood which was later feasted on by Morne Morkel (2/22), Ajit Agarkar (2/27), Umesh Yadav (2/11) and Irfan Pathan (1/12).
Mumbai Indians got off to a shock start by losing both their South African openers with only 5 on the board.
Davy Jacobs, included for the first match in the season, tried a cross-batted heave against left arm spinner Nadeem and was bowled comprehensively for a duck in the second over. More PTI SSR AT
