Mitchell Starc and a crack on the WACA track combined for a stunning delivery to James Vince.

Here's how our ball-by-ball commentary described it: 29.5 absolute snorter! Angled in, pitched on middle, bit off the turf like a legbreak. Plucked out the timbers! Think Steyn to Vaughan at Port Elizabeth in 2004, it was a very special ball to end a valiant knock. No disgrace in getting out when well set this time for Vince. That was a beauty 100/4

Naturally, most on Twitter were awestruck, including a certain Wasim Akram.

It was pretty unplayable.

Was it that unplayable?
