Aliaksandra Sasnovich overcame a blistering start from young Aussie hopeful Priscilla Hon before coming from behind to win in three sets 0-6 6-3 6-3.
The Sydney International wildcard recipient came out firing in her round of 16 clash against the Belarusian.
Hon, who hails from Brisbane, took the first set 6-0 in the extraordinarily quick time of 19 minutes, as Sasnovich had no answer to the young Australian's accurate and upbeat play during the opening exchanges of the match.
The 20-year-old's powerful serve which was clocked at 179 kilometres per hour, plus her youthful exuberance and speed around the court was proving too much for Sasnovich and she didn't win her first game until the third game of the second set.
After the world No.30 had won her first game, the momentum of the match changed as she rallied to win the next four games, breaking Hon's serve and going ahead 4-2.
Hon won her next game but Sasnovich regrouped and weathered Hon's storm before exerting some of her own pressure with her accurate forehand to take the second set.
During the opening games of the third set, it was 1-1 courtesy of both players breaking the other's serve. From there the Belarusian's experience began to show, as she ran Hon around the court.
The former 13th ranked world junior did rally from 15-40 down to take the fourth game of the set to deuce before Sasnovich finally took the drawn out game to lead 3-1.
Sasnovich's higher ranking and experience finally shone through in the end, as she took the final set 6-3 to progress to the Sydney International quarter finals.
