It was only his 11th career appearance in domestic cricket but Billy Stanlake showed why he's been touted as one of the country's brightest pace prospects in the final game of 2016.

Stanlake sealed the match for the Adelaide Strikers in front of a 45,000-strong home crowd, taking the final two Sydney Sixers wickets off consecutive balls to kick off New Year's festivities early in their KFC Big Bash League clash.

But it was the dismissal of former Test wicketkeeper Brad Haddin that gave the sharpest glimpse into the kind of devastating fast bowler the towering Queenslander could become.

Officially listed at 204 cm, Stanlake uncoiled from his precise side-on wind-up and sent down a well-directed 144kph bouncer at Haddin, who was hurried into his hook shot despite being so deep in his crease that he trod on his stumps.
