23-year-old home hope Tristan Schoolkate pressured Jannik Sinner in more than one set.
Then the Italian world number one became too tough.
Sinner is through to the third round of the Australian Open after winning 4–6, 6–4, 6–1, 6–3.
It's always tough to play against a player I don't know well. I thought he served really well and played much better than me at the beginning. And with the crowd, it was an incredible atmosphere, says Sinner in the post-match interview at Rod Laver Arena in Melbourne.
Sinner will face Marcos Giron, USA, in the next round.
