Sam Groth has said that it will be important for him to remain calm during his all-Australian match with Bernard Tomic.
Groth beat another Aussie, Thanasi Kokkinakis, in the previous round and he doesn't want to get carried away in front of what is expected to be a vocal home crowd.
He told reporters: "You try to play the match, not necessarily the name or person at the other end. Obviously you know it's an Aussie because the crowd is going absolutely bunta out there.
"It's not easy but you play who you've got to play. I can't worry about playing Bernard Tomic. I have to worry about getting through to the fourth round."
Groth is currently ranked 82nd in the world.
