Mitchell Starc edged the Ashes closer to Australia's grasp with an unplayable delivery that uprooted James Vince's off stump, and left England needing either a miracle, or an apocalyptic storm to save the series on the fifth and final day at the WACA in Perth.
The left arm fast bowler put an end to Vince's spirited innings with a ferocious angled delivery from around the wicket that cut back like a vicious leg break, leaving the batsman flicking helplessly at thin air as his off stump went cartwheeling.
It was reminiscent of the the great Pakistani fast bowler Wasim Akram, and the man himself was quick to tweet his admiration of the brutish delivery.
He tweeted: "That’s called a JAFFA! What a delivery @mstarc56 you reminded me of my bowling days and I enjoyed it to the hilt! You made left armers proud! @CricketAus"
Earlier, Australia had declared a mammoth 259 runs ahead, in the process, recording their highest Ashes total on home soil with 662/9d, and as the English openers came to the crease, they must have known the task of saving the Test was nigh on impossible.
Alastair Cook's wretched series continued with another low score, and his skipper Joe Root also departed early with a rash stroke to the off spinners Nathan Lyon's first ball.
Vince cracked 12 fours in his sparkling 55, before Starc struck leaving the first innings heroes Dawid Malan and Jonny Bairstow valiantly fighting off the Aussie attack.
The Barmy Army, by far England's best performers this series, were engaged in vigorous rain dances in the stands for much of the day, and were exultant as the heavens opened abandoning play early for the day with England on 132/4.
Every Ashes series has its defining moments, and Starc's astonishing 90mph leg break may well be remembered as one of the great deliveries of this or indeed any Ashes series.
