Hobart Hurricanes 6 for 137 (Graham 39*) beat Melbourne Renegades 5 for 133 (Athapaththu 75*, Gibson 4-24)) by four wickets
Gibson put in a supreme display with the ball to help restrict the Renegades to a modest 5 for 133 batting first at Blundstone Arena.
The turning point in the chase was the 27 runs Hurricanes made in the power surge, which they took in the 13th and 14th overs.
Hurricanes captain Elyse Villani (29) made her highest score this season before she was bowled by a superb skidding delivery from Renegades captain Sophie Molineux.
Renegades slumped to their sixth consecutive defeat and are in last position in the ladder, while Hurricanes are in fifth spot but have a game in hand over the top four sides.
Renegades got off to a fast start with the bat, with opener Hayley Matthews (26 off 23) the prime mover.
Gibson took two wickets in her first over, including Josephine Dooley with an athletic caught and bowled in her outstretched left hand. She was in the groove and another over where she snared two wickets made sure the Renegades never got away.
The fielding of the hosts was supreme, with Ruth Johnston diving full stretch to take a one-handed diving catch with her left to dismiss Molineux.
