Patel bowled his usual accurate and wicket-to-wicket line which fetched him four wickets for 20 runs as Deccan failed to build sustained momentum in their innings after they opted to bat first at the Dr Y S Rajasekhara Reddy Cricket Stadium.
Munaf got able support from Sri Lankan pacer Lasith Malinga who bagged three wickets for 27 runs while Kieron Pollard chipped in with two wickets.
For Deccan, who lost their opening match against Chennai Super Kings on April 7 by 74 runs at the home venue here, Shikhar Dhawan top-scored with a rollicking 24-ball 41 and Daniel Christian chipping in with 39.
The match was, however, marred by controversy with Mumbai captain Harbhajan Singh having a heated and prolonged argument with the field umpires who committed a mistake in not giving Deccan skipper Kumar Sangakkara out.
The incident happened in the 13th over of Deccan Chargers innings with Sangakkara clearly out off the bowling of Munaf though the field umpires A K Chowdhury of India and JD Cloete of South Africa thought it otherwise initially.
Sangakkara dragged the ball onto the off-stump with the bails dislodged and the ball hit wickets for the second time after ricocheting from Mumbai wicketkeeper Dinesh Karthik.
A heated argument followed between Harbhajan and the field umpires with Munaf joining in and play stopped for more than five minutes. Harbhajan was seen arguing with the umpires in an aggressive manner, apparently telling them why they did not refer the decision to the third umpire.
The field umpires, who apparently thought the ball hit wickets after coming off from Karthik's pads, eventually referred the decision to the third umpire who gave Sangakkara out as expected. MORE PTI PDS
