Chasing a massive 208-run target, Mumbai lost wickets at regular intervals and could managed only 170/9 in their 20 overs.
The victory was Delhi's sixth in eight matches and now they have 12 points in the IPL table, three more than their nearest competitors. Mumbai remained stranded at the seventh position after the lost, though they are just four points behind the table-toppers.
Shahbaz Nadeem (2-35), Umesh Yadav (2-36) and Irfan Pathan (2-46) took two Mumbai wickets each whereas Morne Morkel (1-21) was the most economical of the lots.
Young Nadeem struck twice with successive deliveries to rock the Mumbai run chase as the visitors were reduced to 139/6 in 15.2 overs. Nadeem dismissed Keiron Pollard (16) and Ambati Rayudu (62) in his last over to finish his spell with 2 for 35 runs in four overs.
Rayudu played a gem of an innings to revive Mumbai chase but couldn't finish the job. He hit three sixes and five boundaries in his quick-fire 39-ball knock. Pollard too hit a six and a four in his 9-ball cameo.
Mumbai lost Dinesh Karthik (40) after he added valuable 96-run stand with Rayudu.
Delhi pacer Ajit Agarkar clean bowled Karthik to put an end to the dangerous looking fourth wicket partnership for Mumbai. Karthik hit seven boundaries in his brilliant 28-ball innings.
Rayudu hit two consecutive sixes off Shahbaz Nadeem to complete his fifty in just 29 balls as Mumbai slowly revive their run chase.
Rayudu and Karthik hit some lusty boundaries to revive Mumbai innings after the visitors lost three top-order batsmen inside four overs.
Irfan Pathan dismissed Rohit Sharma (12) in the fourth over to reduce Mumbai to 19/3 in 3.1 overs. Rohit hit a six and a four in his 6-ball short stay on the pitch.
Pacer Morne Morkel scalped the big wicket of Sachin Tendulkar (7) in his first over to put Delhi in the front early in the Mumbai innings
Earlier, sent to bat Delhi blitzy 135-run stand between Virender Sehwag and Mahela Jayawardene, and a typically aggressive fifty by the in-form Kevin Pietersen took Delhi Daredevils to 207 at the Feroz Shah Kotla.
Lasith Malinga conceded just a single off his first over, but Mumbai didn't enjoy too many quiet overs in the innings. Jayawardene ripped into his Sri Lanka colleague in this third over, taking 15 off it with three boundaries. He chipped down the track to clip him over midwicket, flicked past square leg and uppishly sliced the third past point.
The Daredevils openers feasted on some wayward Mumbai bowling, flicking full tosses off the pads and slashing the wide ones. Jayawardene was the early aggressor, outscoring Sehwag before the captain opened up against RP Singh, slashing over point and flat-batting a six over long-off.
A deluge of runs followed, courtesy Ross Taylor and Pietersen, who added 41 in just 2.4 overs. Pietersen brought out his signature switch hit, ironically off his namesake who pulled off the same shot in Mumbai's last game. One of Pietersen's innovative hits went for six. A boundary to extra cover in the final over brought up the 200 and a daunting target for Mumbai, looking to settle the score with the Daredevils.
