A nerveless Jordan Silk cameo helped Sydney Sixers get over the line against Brisbane Heat in the 15th match of the Big Bash League.
Silk (46 from 25) took control at the wicket of skipper Moises Henriques (57 from 37), with his side needing 44 from 23 to chase down the Heat's 165.
He fell with six balls remaining but by then his side only needed six runs off Ben Cutting's final over.
Tom Curran hit a full toss to the cover boundary from Cutting's second delivery and the visitors won with three balls and five wickets to spare.
The loss was the Heat's seventh straight and third in their current campaign and it came despite a mature 84 from skipper Chris Lynn.
The captain exploded once reaching the milestone, hitting five sixes to finish with 84 off 55 balls.
Lynn took it upon himself to build the innings after the early loss of Max Bryant.
Jimmy Peirson (23 off 17) joined Lynn with the Heat 5-91 in the 13th over and the paired steered the Heat to 163 before Lynn was dismissed with three balls remaining.
Heat spinner Mujeeb Ur Rahman's second-over maiden put Brisbane in the box seat before Henriques and debutant Justin Avendano rallied.
A rookie error ended Avendano's (30 from 24) entertaining innings, run out by a Cutting direct hit when he failed to ground his bat while completing an easy single.
Henriques soldiered on though, before Silk's crafty knock saw them over the line.
