Marcus Harris' crucial Test innings could come at a financial cost.
The Australia opener edged and near-missed his way to 50 after lunch on day two of the Boxing Day Test.
It is his highest Test score in 18 innings, going back to his career-high 79 against India in the 2019 New Year's match, and his third half-century.
He had also top-scored as Australia reached a shaky 4-148 at lunch.
But however this knock ends up, it will probably leave Harris out of pocket.
He is likely to be fined after the stump mic clearly caught an exchange with English bowler Ben Stokes.
Harris was given out lbw off Stokes, but he successfully reviewed the decision.
He immediately called for the review, suggesting Harris was confident there had been an inside edge onto his pad.
After the hotspot technology showed nothing to help the Australian, Snicko clearly picked up the inside edge.
Stokes then asked Harris what had happened.
"I wasn't, like, 100 per cent sure ... I thought it might have clipped both pads and maybe an inside edge," the Australian told him.
"Hotspot's f***ing hopeless."
Teammate Travis Head was fined for swearing at himself while batting in the first Test.
But Harris' expletive would be nothing compared to the swearing under their breath from the English pacemen as he continually frustrated them.
They had beaten his outside edge several times and Harris never looked fluent.
Still, he was there, having faced 128 deliveries to lunch.
As the Steve Smith and Marnus Labuschagne dismissals showed, this MCG green top continues to be difficult for batting.
Unlike England on day one, Harris had played no reckless shots.
The Ashes are going so badly for England, they might be playing Harris back into form.
After Harris only managed three and 23 in Adelaide's second Test, he looked unlikely to play at his home ground on Boxing Day.
But coach Justin Langer and the selectors have stuck with Harris in the hope that they can finally translate solid Sheffield Shield form into consistent Test runs.
