Marcus Harris might have been under pressure following a disastrous start to his Ashes campaign during the first two Tests, but his first innings in Melbourne was saved by hotspot.

Given out LBW in the 31st over of the innings on just 36 to the bowling of Ben Stokes, Harris wasted no time in reviewing, with there seemingly being two noises.

While hotspot didn't pick up a major mark on the inside edge of Harris' bat, snicko picked up a large sound as the ball went past his bat.

It was enough to spare the wicket of Harris, much to the dismay of England.

In a conversation with Stokes the following over, Harris was picked on the stump microphone as saying "I wasn't like 100% sure but it had a mark on me [sic] bat. I sort of thought it might have clipped both bats and a little inside edge. Hotspot is f**king hopeless."

The review came at a crucial time for the Aussies, who were 3 for 103 and would have been four down in pursuit of England's first innings total of 185 had the decision stood.

Harris would go on to score a confidence-restoring 76 from 189 balls, departing to the bowling of James Anderson shortly before tea with Australia moving to 6 for 180 at the time of his dismissal, still five runs behind England's first innings total.

The score may be enough for Harris to line up during the fourth Test in Sydney next week, with the opening batsman under pressure from Usman Khawaja, who is also in the squad and was overlooked at both the top of the order, and at number five, with that spot going to South Australian Travis Head.
