Smith powers Sixers into top spot with incredible ton

Steve Smith has lived up to his billing as the Big Bash's marquee signing by belting his way to the first men's century in Sydney Sixers' history, helping the side move atop the KFC BBL|12 standings with a 59-run win over the Adelaide Strikers in Coffs Harbour.

In his second game back from a three-year BBL hiatus, Smith (101 from 56 deliveries) equalled his highest score in T20 cricket and joined forces with Kurtis Patterson (43) to forge the largest partnership of the BBL summer after the Sixers were sent in on Tuesday night.

The knock continued a blustering summer at the crease for Smith that also yielded an unbeaten 200 against the West Indies and a century against South Africa.

Smith's innings, the equal-best of the BBL summer, came to an end when he scrapped plans to sneak a second run but slipped as he turned back to his crease, only to be run out by Matt Short.

On a batter-friendly deck, the Sixers still had some work to do to defend their total of 5-203.

But called in to replace Nathan Lyon (knee soreness), India-bound spinner Todd Murphy had a hand in three quick wickets and finished with the best figures of his young BBL career (3-35) to make the equation easier.

Ben Dwarshuis (3-28) then bowled Alex Carey on 54 to put the final nail in the coffin.

The loss means the Strikers desperately need to defeat the second-placed Perth Scorchers this Friday to keep their finals hopes alive.

The Strikers missed three early chances to dismiss Smith, most notably in the second over when the ball rolled slowly from Smith's bat onto the stumps but failed to dislodge the bails.

Smith then went into overdrive, kickstarting his innings with consecutive boundaries off Wes Agar and bringing his half century up with a four past deep point.

For the longest time told he was unsuited to the shortest format, Smith looked comfortable at the crease and with opening the batting – something he has never done at T20I level.

With the last ball before the drinks break, Smith equalled his previous BBL high-score of 66 and then became the third man this summer to hit a BBL century with a six over deep backward square leg.

The Sixers lost Smith, Patterson and captain Moises Henriques in the space of six balls but a late cameo from Jordan Silk (31no) ensured the total would finish as an imposing one.

With no Chris Lynn, Short designated himself chief agitator after Test firebrand Travis Head was caught by Sixers wicketkeeper Josh Philippe for five.

But he slogged Murphy to deep square leg where he was caught by Patterson on 40, leaving the Strikers in search of another leader.

They found one in Carey, who kept the Strikers ticking along after the quick losses of Adam Hose (caught off Murphy's bowling) and Colin de Grandhomme – run out by Smith during the same over as Hose was dismissed.

Carey made the most of the short boundaries to reach a half century in his second game back from Test duty before Dwarshuis' yorker crashed into his stumps. The Strikers were all out for 144 in the 19th over.

Lyon is expected to be available to face the Sydney Thunder this Saturday, with the Sixers revealing he was rested as a precaution ahead of the upcoming India tour.

"Lyon reported minor knee soreness after travelling to Coffs Harbour this morning and consulted Sixers medical staff," they said in a statement pre-match.

"It was decided collectively that while the knee does not appear to present any further risk or require a scan, he will be rested for tonight's game and monitored."
