Sixers on the up after showing super over credentials

Super over veteran Moises Henriques says his Sydney Sixers side will learn plenty from their dramatic one-run win after twice looking dead and buried against KFC BBL rivals the Sydney Thunder at the SCG.

It took two pieces of brilliance from the captain in the extra over to lift his side to victory in a scrap that had countless twists and turns on Saturday night.

First, he exposed his stumps to help a ball over short fine leg, before somehow ramping a low full toss over third man to get the Sixers to 16 in their super over.

That was despite losing Tom Curran from the first ball of the super over after he had just smashed 35 from 17 balls to rescue them following Henriques' (41 from 30) initial departure.

English import Curran then stepped up with the ball to keep Usman Khawaja and Alex Hales to 15 in the Thunder's reply, Hales managing a four when he needed a six to win from the last ball.

It was the fourth Big Bash League super over, with Henriques the only man to feature in all of them and now boasting a 2-2 record.

The win also lifted the Sixers to 3-2 this season and handed the Thunder their first loss after two wins and a split-points decision after the smoke-enforced no-result in Canberra.

"We almost batted ourselves out of the contest and TC (Curran) got us back into it," Henriques told Fox Cricket.

"It was a fantastic game of cricket ... it's what you play cricket for, to entertain and these are the games (that help) you get better because you're under pressure."

He said the double blow against South African Chris Morris in the super over was a classic "cat and mouse" against an opponent he knew well.

"I knew the best way was to go sight screen, just not the one in front of me," he said.

"They both paid off; I only just got the first one and (the second was) a little bit of luck, a bit of skill and bit of everything mixed in there."

Curran, who also blasted 43 from 21 in his previous game, said he was happy Henriques had trusted him with a large batting role to go with his bowling duties.

Earlier Thunder captain Callum Ferguson retained the golden cap as the competition's leading run-scorer, with his sensible 52 from 42 ensuring the Thunder had a total to defend after slipping to 7-115 in the 17th over.

They started well in defence of that though and were left to rue what Ferguson described as a "missed opportunity" post-game.

Sixers' import James Vince missed the game after being struck on the elbow in the nets but has been cleared of any structural damage, while Sean Abbott is being monitored for a side strain.
