The Perth Scorchers have bounced back with a thrilling final-ball victory over the highly-fancied Melbourne Renegades under the roof at Etihad Stadium.

The Renegades found themselves short on bowling options when West Indian import Dwayne Bravo was stretchered from the ground with what appeared to be a nasty hamstring injury sustained while fielding.

Defending 8-148, Renegades skipper Aaron Finch was forced to bowl the final over of the innings, with the Scorchers requiring nine runs for victory.

But it would be drama-packed to the very last delivery. Finch dismissed Mitchell Marsh on the second ball of the over and ran out Adam Voges from short-cover after doing the fielding from his own bowling.

The equation read, two to win from the final delivery with Scorchers all-rounder Ashton Agar on strike.

Finch delivered a waist high full-toss which Agar deposited deep into the crowd over mid-wicket for six to seal a four-wicket win.

Earlier, spin twins Sunil Narine and Spartan Brad Hogg helped put the brakes on the Scorchers’ run chase.

Hogg was luckless in his 0-31 from his four overs. He was not required to bat as the Renegades scored just 29 runs from the final five overs to be well short of their projected target.

Spartan Mitchell Johnson was among the Scorchers’ best with 1-31 from his four overs, including the big wicket of Tom Cooper.

The win moves the Scorchers to the top of the BBL table while the Renegades drop out of the top four.
