Defending champion Jannik Sinner dismissed eighth seed Alex de Minaur 6-3 6-2 6-1 to reach the Australian Open semi-finals and extend the country's decades-long wait for another homegrown singles winner at the Grand Slam on Wednesday.

A night that promised so much for Alex de Minaur ended with another trip back to the drawing board following a loss that will require some serious soul-searching.

Alex de Minaur noticed one very strong comment made about his performance versus Jannik Sinner and he wasn't interested in letting it slide. On Wednesday, the home favorite player exited the Australian Open in the quarterfinal after the No. 1 seed handed him a 6-3 6-2 6-1 loss. Now, the Italian leads their head-to-head 10-0.
