Hobart Hurricanes 133 for 8 (Jewell 70, Crawley 30, Hatcher 3-25, Coulter-Nile 2-22) beat Melbourne Stars 131 for 7 (Cartwright 57, Webster 27, Ellis 2-12, Meredith 2-25) by two wickets
Coming off scores of 54, 54 and 28, Jewell maintained his rich vein of form, beating his previous best T20 effort of 61 not out. He struck eight fours and two sixes and the left-hander's aggression always had his side well ahead of the required run rate.
Jewell reached his 50 off just 30 balls with a cover-driven boundary and then smashed a six over midwicket off Luke Wood and another one over deep backward square leg off Adam Zampa.
Hurricanes stumbled to the finishing line once Jewell was caught behind off the impressive Hatcher, who returned his best BBL figures of 3 for 25.
Earlier, Cartwright hit eight of his teams' 12 boundaries off the bat, with no other Stars batter finding the rope until the 14th over.
A third-wicket stand of 60 between Cartwright and Beau Webster stabilised the innings after both openers fell early. Big-hitting import Joe Clarke was run out after a mix-up and Tom Rogers holed out to square leg In the fifth over. At one stage, Cartwright struck six fours in the space of nine balls but the boundaries dried up for almost eight overs.
Webster, who struggled with his timing to find gaps, broke the drought with a scoop to fine leg, but was out soon after off a leading edge. Stars scored just nine runs off their two Power Surge overs.
Ellis used seven bowlers across the first 10 overs with fellow quicks Riley Meredith (2-25) and Faheem Ashraf (2-29) performing well.
