Already out of contention for a play-off berth, Punjab played freely with Marsh (63) and Mahmood (80) punishing the errant Mumbai bowlers with a slew of fours and sixes after being put in to bat at the picturesque HPCA stadium.
Mahmood struck eight fours and four sixes in his 44-ball knock while Marsh hit 11 fours during his 47-ball innings. The duo rescued the Punjab side with a 148-run third wicket stand in 14.2 overs after the hosts were reduced to six for two in the third over.
For Mumbai, Lasith Malinga grabbed three wickets for 39 runs while Nathan Coulter-Nile, Rishi Dhawan, Harbhajan Singh and Kieron Pollard took a wicket apiece.
Punjab had the worst possible start with openers Mandeep Singh (1) and Adam Gilchrist (5) back in the dressing room by the third over with just six runs on board.
Mandeep misread a Dhawan delivery which pitched outside off and ended up spooning it straight to Pollard at mid-off in the second over.
