The Delhi Daredevils' Indian Premier League play-off prospects suffered a setback as they went down by 39 runs against the Mumbai Indians.
Set at target of 184 at the Brabourne Stadium, the Daredevils finished well short on 144-7 after a middle-order collapse.
The top three - David Warner (31), Virender Sehwag (20) and Gautam Gambhir (17) - all fell after making starts as, from a promising position of 72-1 in seventh over, wickets started to tumble.
Left-arm spinner Ali Murtaza (2-18) collected two scalps as Delhi lost five in 33 deliveries to slump to 94-6.
And, despite a defiant 33 not out from Andrew McDonald, there was no way back for the visitors.
Earlier, Kieron Pollard smashed 45 off 13 balls to get the Indians up to 183-4 after opting to bat.
The Trinidad all-rounder dispatched five sixes, including three in the final over of the innings bowled by medium pacer McDonald (1-42).
Pollard's late assault built on some less spectacular work from the top five, who all reached double figures.
The Indians now sit six points clear at the top of the standings but the Daredevils, with two games remaining, are locked in a tight battle for a top-four finish - and with it a play-off place.
They are level on 12 points with three others, while a further two teams are two points back with a game in hand.
