Adam Zampa's attempt to run out Tom Rogers was the eye-catching moment of an otherwise routine win for the Renegades, who are now up to third in the table after eight matches
Melbourne: Melbourne Renegades 141-7, Melbourne Stars 108-9 - Melbourne Renegades won by 33 runs
Melbourne Renegades made a timely return to form to beat city rivals Melbourne Stars by 33 runs at the MCG.
Martin Guptill, Shaun Marsh and Mackenzie Harvey all struck 32 in a first innings 141 for 7.
In reply, Stars were reduced to 18 for 4 and never recovered, eventually reaching 108 for 9 from their allocation.
The eye-catching moment of the contest, however, occurred in the final over of the Renegades' innings.

But umpires, using video technology, adjudged that the Australia legspinner's arm had gone past being vertical - the point at which he would normally have been expected to release the ball - before taking off the bails.
A bowler is not entitled to run out the non-striking batter once they have passed this point, as per the laws of the game.
The incident sparked a succession of boos from the assembled crowd.
Stars were the favourites at the halfway point but they lost four of their top five inside 27 balls of the reply.

Rogers bowled Joe Clarke (0) and Thomas Rogers (1) on either side of dismissing Beau Webster (8) caught and bowled.
The 28-year-old, formerly of Sydney Sixers and Hobart Hurricanes, completed a maiden T20 five-for with the dismissal of Hilton Cartwright (20) and Luke Wood (1) to cap a memorable day.
Nick Larkin arrived in the fifth over and struck a 40-ball 48 but was unable to rouse Stars, who have now only returned two wins from their seven group matches.
Renegades are now back in the playoff positions with eight points, leapfrogging Sixers and Adelaide Strikers thanks to a fourth tournament win, but have played at least one game more than the remaining seven sides.
