Alex de Minaur overcame a one-set deficit and his own serving yips Saturday afternoon to defeat 31st-seed Francisco Cerundolo in a marathon third-round Australian Open match.

Here’s the remarkable truth about Alex de Minaur. Apart from the remarkable ability to overachieve, he’s completely unremarkable. It’s remarkable. I’ve searched his closet and there’s not a single skeleton to be found.

It was the opening round of the 2017 Australian Open in de Minaur’s first main draw at his first major championship in his home country, when the then-17-year-old saved a match point in the fourth set before beating Gerald Melzer in five sets and almost four hours.

Alex de Minaur is bidding to equal a career-best result at the Australian Open in his third round match versus Francisco Cerundolo at Rod Laver Arena on Saturday. The eighth-seeded Aussie will reach the fourth round at Melbourne Park for the fourth time if he can get past the Argentine 31st seed.
