Moises Henriques hit two sixes and a four in the super over to give Sydney 22 in total
Australia's domestic T20 cricket competition, which regularly attracts crowds of more than 40,000 people, reaches its climax with the final on Saturday for which the Perth Scorchers qualified yesterday.
But Brisbane Heat and Sydney Sixers had to scrap it out today for their spot in a game that went right down to the wire.

Brisbane had batted first and managed 167/8 from their 20 overs thanks to 46 off 27 balls from captain Brendan McCullum.
But Sydney chased admirably with Moises Henriques making 64 from 34 balls, although he fell before the end.

The Sixers needed three to win from the final ball but could only manage two, forcing a one-over tie-breaker to decide the match.
Henriques was sent out again with team-mate Colin Munro and did not disappoint, hitting two sixes and four as Sydney put up an impressive 22.

McCullum once again went out but the Heat could only manage 15 and the Sixers made it through to the final.
Led by Australia international Henriques and with former England man Michael Lumb in the ranks, the Sydney outfit will face Ian Bell and the Scorchers at the WACA on Saturday. The final will get going at 8.15am GMT.
