Spartan Mark Steketee played a crucial support role as Chris Lynn piloted the Brisbane Heat to victory over the Sydney Thunder.

With 45 still needed from the final four overs, Steketee came to the crease at seven wickets down and did more than just rotate the strike for the dominant Lynn.

He helped turn the ascendancy with a straight six off fellow Spartan Andre Russell off just the second ball he faced to put the Heat in the box seat.

Lynn played a lone hand with an unbeaten 85 as the Heat chased down the defending champions’ 7-157 with two balls to spare.

Steketee led the attack with the new ball taking 1-18 from his four overs. It included the prized scalp of Thunder captain Shane Watson for a duck in his comeback from injury.

Spartan Mitchell Swepson knocked over Kurtis Patterson with a skidding flipper on just the second ball he delivered but was given some brutal treatment when handed the daunting task of bowling the final over of the innings.

Andre Russell returned with the black S6R DreRuss bat and despite some promising signs with a thumping boundary over point, the West Indian all-rounder went down swinging, caught at long-off by fellow Spartan Joe Burns for 8.

The game would be decided on Lynn’s bat as he took on the boundaries with a one-man show.

The loss leaves the Thunder languishing on the bottom of the ladder, winless after three games. They can take solace from the Brisbane Heat in the 2012-13 season when they lost their first three games and went on to win the second season of the Big Bash competition.
