After Aaron Finch blazed 109 from 68 balls in a total of 5/175 at the SCG, Smith and Josh Philippe (61 from 42) starred in reply. The Sixers finishing 3/176 with eight balls remaining.
In his final match of BBL|09 before he joins the England T20 squad, seamer Tom Curran claimed 3-27 from his four overs to finish the campaign with 22 scalps at an average of 19.4.
An exhausted Steve Smith, due to the humid conditions, said it was just nice to contribute to the win.
“Little bit to do tonight, it made things a little bit easier the way (Josh Philippe) was going when I came out, geez he was striking some balls very cleanly again,” said Smith
“I have loved being back for the Sixers, the last two games, it’s been six years since I played in the Big Bash. We’re into second spot for a little while now pending results.
“It’s been great to see the fans come out and we put on a good show for them fortunately.”
Coming to the crease at 1/49 in the sixth over, Smith showed the composure that has become his trademark, hitting seven boundaries and one six during his knock, that included a few switch hits.
Philippe was brutal at times clearing the rope on three occasions and reaching it five times.
Smith shared a 50-run second wicket partnership with Philippe and a 73-run stand with Daniel Hughes (19 not out from 14) to close out the match.
Commenting on the loss of Curran, Smith praised the England allrounder for his efforts with bat and ball in BBL|09.
“He’s been great around the group. A terrific guy, great skills with the ball, thought he bowled really well again tonight,” said Smith.
“(Tom) has been magnificent with the ball, and under pressure with the bat as well.
“He’s going to be a big loss for us, but he’s done his job as an overseas player helping us get to the finals, now it’s our job to get it done for him.”
