Johanna Konta became the third British player to reach the third round of the Australian Open with an assured 6-3 6-2 victory over Japan's Naomi Osaka.
The 25-year-old ninth seed produced a confident all-round display to see off the promising 19-year-old.
She joins Andy Murray and Dan Evans in the last 32 and could be joined there by Kyle Edmund and Heather Watson, who also play on Thursday.
Konta will face either Caroline Wozniacki or Donna Vekic next.
