Mitchell Starc has sent a warning to batsmen around the world with a vicious delivery that Joe Burns had absolutely no answer to.
During New South Wales' JLT One-Day Cup clash against the Queensland Bulls on Friday, Starc powered down a short-pitched delivery that Burns had no time to deal with.
The star batsman managed to get some contact on the ball but was caught off balance, and forced to knock the bails off his own stumps as his bat flew around wildly.

Meanwhile, South Australian skipper Travis Head will make his Ashes case against an all-Test NSW bowling attack in the first of three crucial Sheffield Shield fixtures.
Australian selector Mark Waugh has named Head in a group of batting allrounders vying for the Test No.6 spot with Marcus Stoinis, Glenn Maxwell and Hilton Cartwright.
While he hasn't set the world alight in Australia's limited-overs tour of India, Head will get an opportunity to press his claims in a day-night match against NSW from October 27 at Adelaide Oval.
Stoinis has looked solid at No.6 in the 50-over format. Maxwell and Cartwright struggled and were dropped during the ODI series.
Head said selectors had been open about how crucial Shield runs would be leading up to the Ashes.
"I knew coming here that if I got runs, I would sort of move a bit closer to that and at least put my hand up," Head said in Hyderabad.
"I haven't been able to do that so it probably makes the next three Shield games more important to put my case forward."
Head made 119 runs at an average of 23.8 in the ODI series with a top score of 48 not out in the final match.
He struggled to get on top of the Indian attack but turned that around in the second T20, with his unbeaten 48 off 34 balls helping guide Australia to an eight-wicket win.
Head said it had been a disappointing tour with many of his dismissals caused by poor execution.
"I've been able to get some starts throughout the tour and not go on," he said.
"To get some runs the other night was nice - it's been a tough tour."
The Redbacks' clash with the Blues will pit Head against Mitchell Starc, Josh Hazlewood, Pat Cummins and Nathan Lyon, the attack likely to face England from November 23 at the Gabba.
"I don't think anyone in the team will be thinking about the (Test) No 6 spot or whatever spot in the Australian cricket," Head said.
"I'm just looking forward to playing the best team in the country and trying to win the game."
