Malan played his innings with the help of nine sixes and three fours and scored his second consecutive big score after scoring an unbeaten 88 against Northern Superchargers last time.
Alex Hales (38 off 20), Tom Koehler-Cadmore (30 off 17) and Ian Cockbain (20 off 14) also made their mark, with Cockbain hitting the winning boundary.
Phil Salt (70 off 46 balls) was the top scorer for the first Original as he posted only the Northern Superchargers 200-5, the second-highest score in The Hundred, against the Originals at Headingley last season.
Salt, who was dropped for 29 by Malan, scored 84 runs in 51 balls with Jos Buttler (41 off 25) for the first wicket, while Tristan Stubbs (27 off 10 balls) and Laurie Evans (26 runs). 11 balls) also had a crunching cameo.
Stubbs hit fellow South Africa’s Tabrez Shamsi for four consecutive sixes but took the wicket off the fifth ball. Together with Evans and Salt, he added 52 runs in the last 20 balls at Manchester.
For the Rockets, Samit Patel (2-20 off 20 balls) impressed as his fellow bowlers were carted off and Alex Hales was quick on the field, catching Butler, Stubbs and Andre Russell (16 off 10) in the deep. Got it done
Alex Hales and David Malan then gave the Rockets the start of the chase and shared a 37-ball 85-run partnership for the first wicket.
Malan went on to reach fifty off 23 balls with a six off Russell at deep midwicket. He fell two runs short of a century, meaning Will Smed of Birmingham Phoenix remains the only century in the competition to date.
