Ash Barty has dropped just five games on her way to a third round appearance at the Australian Open.
It took Barty just over an hour to defeat China's Yafan Wang 6-2 6-3 to make her third consecutive appearance in the last 32.
The win continues a good start to the 2019 season for the Queenslander who is coming off a Sydney International final.
"I felt like today was pretty clean, except for a couple of games where I got passive," Barty said.
"Very happy with the way I have started 2019, not just here in Melbourne but also in Perth and Sydney, hell of a start."
However, the match wasn't without its shaky moments with the world no. 95 breaking Barty in the third game of the second set.
The match started routinely but a calm and composed Barty quickly broke before cruising to an opening set win in 28 minutes.
Unable to continue the momentum from the first set, Wang, who had settled into the match, capitalised on this opportunity, breaking the world no.15.
It was all class from a free-swinging Barty though, dropping just two points on her way to leveling the set before going on to win three straight games to advance to the next round.
It wasn't the same story for fellow Australian's Zoe Hives and Astra Sharma who both went down in straight sets in their second-round games.
Barty faces good friend Maria Sakkari, who ousted Sharma 6-1 6-4, in her next singles match.
"We have played a couple times now. She's one of the best movers and competitors out there. Whichever way that goes, my next singles match will be very tough."
