Strikers had gone three from three in the competition and took their winning streak to four by chasing down Heat???s 152-6 with seven balls to spare at The Gabba.
Travis Head (57 not out from 40 balls) and Alex Ross (36 from 24) put on a fifth-wicket stand of 87 after Strikers had staggered to 63-4, while skipper Johan Botha sealed the triumph with a maximum down the ground.
Adelaide now hold a two-point cushion over Sydney Sixers at the top of the Big Bash ladder, while Heat – who left out Andrew Flintoff for Sunday???s encounter ??? are second bottom having picked up just one win so far this term.
Heat could only muster nine runs from their first three overs after being put into bat by Strikers but openers Peter Forrest and Jimmy Peirson soon got their eye in, plundering 49 from the next four, albeit not always with the cleanest of strikes.
Forrest (33 from 31 balls) and Peirson (27 from 17) departed in the eighth and ninth overs respectively, while Dan Christian (6) went cheaply in the 11th as Strikers ??? who rested seamer??Shaun Tait and were shorn of the injured Brad Hodge ??? battled back.
Nathan Reardon (31 from 30), Chris Lynn (28 from 16) and Ben Cutting (21 from 15) made valuable contributions for Heat, but Strikers’ slow bowlers Craig Simmons (2-26), Adam Zampa (1-13) and Botha (1-25) did a good strangling job, shipping just 64 runs from their combined 11 overs.
Simmons, however, was slightly less effective with his batting, making 15 before he was dismissed by last season???s top Big Bash wicket-taker Cameron Gannon after picking out Reardon at square leg.
Strikers were three down with just 49 on the board, when Jono Dean (8) and Tim Ludeman (14), who made fifties during the side???s win over Hobart on New Year???s Eve, were sent packing.
Kieron Pollard (6) came and went to leave the visitors teetering but Head and Ross did the grunt work, before Botha (8 not out) ended the contest in style from the penultimate ball of the 19th over.
