Sam Groth has said that he was thankful his serve was strong during his first-round win at the Australia Open earlier today.
The Australian beat Serbia's Filip Krajinovic 6-3 7-6 6-4 to set up a match with compatriot Thanasi Kokkinakis in the second round.
The world number 82 told reporters: "Obviously I live in Melbourne now and haven't had great runs in the main draw, be it in quallies or the main draw.
"During the second set I wasn't making as many groundies as I wanted to, but thankfully the serve held true."
The win is Groth's first at his home Grand Slam event, and just his second in the four majors.
