Melbourne Renegades 175/6 (Finch 70*, Sams 3-33) beat Sydney Thunder 174/6 (Rossouw 53, Ross 39) by four wickets
The Renegades looked in control for most of the chase but got a sure end from Finch to see them reach 175 and claim victory at the Marvel Stadium.
The hosts needed 11 runs from the last over but the Thunder’s hopes were boosted when fast bowler Gurinder Sandhu caught Akil Hossain on a slog.
The Renegades still needed 10 runs from four balls when Finch (71 from 43 balls) took strike, but he hit a six and scored two runs in each of the next two balls to finish the job with one ball to spare.
Finch helped Renegades captain Nic Maddinson (39 off 28 balls) pull off the highest successful chase ever in BBL 12, while Jake Fraser-McGurk (24 off 18 balls) also impressed early.
Daniel Sams was one of the Thunder bowlers and almost turned the contest in their favor just as the Renegades looked set to return home.
Thunder won the toss first and elected to bat as they looked to bounce back from a horror show in their last outing when they were all out for just 15 runs.
Alex Ross (39 off 23) and Oliver Davies (33* off 18) stitched together a crucial 42-run stand at the end of the Thunder’s innings to set the Renegades a tough target till Finch came on.
Left-arm spinner Akil Hossein again opened the bowling for the Renegades and ensured that the under-fire Thunder made a nervous start with a tight line in the powerplay.
England opener Alex Hales this time increased the run rate by blasting Hossein over the boundary to take the Thunder to 15 for no loss, although Matthew Gilks fell one run later.
While it was a much-improved performance from the Thunder, they will be sweating on the fitness of Jason Sangha after he went down heavy ground while fielding and injured his shoulder.
The victory for the Renegades was their first over the Thunder in their last five outings and moved them to a 2–0 record after earning the wooden spoon the previous three seasons.
