Melbourne Renegades 6 for 164 (Webster 36, Laughlin 3-31) beat Brisbane Heat 120 (Heazlett 56, Boyce 4-15) by 44 runs

The Melbourne Renegades overcame an opening onslaught from Chris Lynn and Sam Heazlett to conjure a remarkable comeback 44-run victory over a stunned the Brisbane Heat, whose playoffs push crashed to a halt at the Gabba.

Chasing 165, openers Heazlett (56) and Lynn (41 off 15) smashed 84 in the powerplay before the Heat lost three wickets in four deliveries out of nowhere. After Heazlett fell in the 13th over, the home side wilted further and lost 7 for 7 with hero Cameron Boyce finishing off one of the most astonishing comeback victories.

The Heat's 10 for 36 collapse is the worst in BBL history and hard to fathom after they dominated the majority of the contest. After electing to bowl, the Heat restricted the Renegades to a seemingly under par 6 for 164 before enduring a batting meltdown.

The Heat (5-6) remain in sixth spot, while the Renegades (2-9) have won consecutive matches.

Heat claw back after strong Renegades start

A struggling Marcus Harris has been reflective of the Renegades' horror season. He shelved the big shots early in a bid to curtail the menacing bounce from a fired up James Pattinson, who was fresh off a five-wicket haul against the Adelaide Strikers.

Pattinson continued to bowl short of a length and the out-of-sorts Harris succumbed to the pressure when he edged a short delivery.

Ever reliable Shaun Marsh, in contrast, was in a belligerent mood. He may have, however, received an ounce of luck in the fourth over after appearing to be caught behind the wicket from an inside edge off Josh Lalor.

Sam Harper hoped to support Marsh and attacked Mujeeb Ur Rahman at the backend of the powerplay. He blunted the spinner firstly by clubbing a six down the ground and then perfectly executed a clever paddle to the long-on boundary.

The Renegades eyed a healthy total until Marsh threw his bat - literally after slipping from his grasp - but only succeeded in spooning a return catch to Ben Laughlin.

The Heat's fightback continued when Harper hit straight to short midwicket as the Renegades fell to 3 for 63 at the midpoint.

Patel and Nabi rally at the death

The Renegades were shackled in the middle overs until consecutive sixes by Will Sutherland in the 12th over relieved the pressure although the second was helped over the boundary by AB de Villiers, who uncharacteristically fumbled at long-off.

Sutherland's cavalier approach eventually backfired after holing out in the 14th over to negate the Renegades' momentum.

The Heat were fuelled by aggressive captaincy from Lynn, who brought spearhead Pattinson back on after the wickets of Harper and Sutherland. But Beau Webster superbly counterattacked in the 15th over with an astounding thump over the long-on boundary to sour Pattinson's figures.

Webster's enterprising knock ended in the 17th but late fireworks from Samit Patel, who smacked a timely 23 from 10, and Mohammed Nabi revived the Renegades.

Heazlett and Lynn plunder before Heat collapse

The Renegades' momentum quickly evaporated after a loose Andrew Fekete leaked three boundaries in the first over. Patel's spin didn't fare any better, as a hot Heazlett whacked five boundaries from his first nine deliveries faced.

An overshadowed Lynn luckily survived two inside edges, which both missed the stumps and rocketed to the boundary to continue the Heat's soaring run rate. It wasn't long until Lynn found his groove and he smacked Nabi's first two deliveries for massive sixes to suddenly overtake Heazlett. Another boundary notched the 50-run stand off just 22 balls as Nabi's hapless over cost 24 runs.

The carnage continued until Lynn holed out on the last ball of the powerplay. De Villiers hoped to inflict more pain but was bowled second delivery by a flighted Boyce delivery to silence the Heat faithful, who were further stunned when Matthew Renshaw departed for a golden duck.

Heazlett was forced to play cautiously but notched his first BBL half-century, as the Heat reached 3 for 103 after 10 overs.

Boyce completes astonishing Renegades victory

After the earlier flurry, the Heat went six overs without a boundary as the pressure built and Heazlett cracked when he edged behind off Patel, who then claimed Jimmy Peirson next ball to flip the match once again.

Joe Burns was then run out after a horrible mix up with Ben Cutting to continue the Heat's stunning slide. Cutting couldn't reprieve himself after being trapped unluckily lbw by Christian with replays indicating the ball was missing leg stump.

The Heat spectacularly flamed out with Boyce fittingly finishing it off with wickets off successive deliveries to ensure the Renegades notched a win for the ages.
