And in an added twist, he did so with Federer at the opposite end, as he practised with Marat Safin.
In September 2018, Millman beat Federer in hot and humid conditions at the US Open.
The weather in Melbourne is not expected to be as difficult on Friday but Millman says he intends to make the match physical for Federer.
He said: “I think for me, I try to make things as physical as possible. I’ve got to try to do that. That’s how I play. I’ve got to try to keep as good a quality as possible because we know that Roger transitions so well, he jumps on anything short. He’s so good at moving in and out of the court really quickly.
