Perth’s English opener Liam Livingstone was twice felled by balls to his groin region but bounced back to turbocharge his side’s chase. Livingstone repeatedly cleared the rope including tonking compatriot Richard Gleeson onto the roof.
With the match slipping away, the Renegades had a chance when Livingstone – on 49 – miscued a Dan Christian half-volley. But just a moment after telling Channel Seven commentators that his side’s cause was not yet lost, Renegades captain Finch spilled a catch running back with the flight at extra cover.
Gleeson struck when Livingstone (59 from 39 balls) was eventually snaffled by Finch, but by that point the Scorchers had already reached triple figures for no loss inside 10 overs.
Livingstone’s fellow opener Josh Inglis (51 from 33) gave a return catch to Richardson after being deceived by a slower ball.
However Mitchell Marsh, Cameron Bancroft and Tim David all produced cameos to help Perth to a six-wicket victory with six balls to spare.
Sent in by the Scorchers – who themselves had started the season slowly – the Renegades fell into a hole at 3-48. Finch mistimed a pull to fall for a golden duck, before Marcus Harris – opening in a rejigged top-order – became Jhye Richardson’s second victim, departing for 14.
Shaun Marsh (two) was at first tied down and then removed by younger brother Mitchell as Livingstone took a catch in the deep.
Things looked grim, although the Renegades innings was resuscitated by two men who stand 26 centimetres apart in height.
The diminutive Sam Harper finally went on with a start, combining his array of attacking strokes with discerning restraint en route to 73 from 46, benefiting from being dropped in the deep by Chris Jordan on 47.
Down the other end, the lanky Beau Webster teed off late to finish 59 not out from 40, an innings which included four mighty sixes.
English all-rounder Samit Patel made his Renegades debut less than 24 hours after touching down in Melbourne. The veteran came in at No. 7 and made an unbeaten two from as many balls before opening the bowling with his left-arm spin, conceding 35 from four wicketless overs.
The silver lining from Finch and Richardson’s imminent departures is the fact the Renegades will be forced to tinker, for what they have delivered so far hasn’t been good enough.
The Renegades’ quest for a win will continue on Friday night at Marvel Stadium in a return derby against the ladder-leading Melbourne Stars. That is Gleeson’s last match before he is replaced by Afghanistani Mohammad Nabi.
