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 follows Andy Murray and Dan Evans in making the last 32 and could be joined there by Heather Watson, who plays Jennifer Brady on Thursday.
But Kyle Edmund was beaten 6-2 6-4 6-2 by Spain's Pablo Carreno Busta.
Konta, who will face either Caroline Wozniacki or Donna Vekic next, faced a player rated one of the most promising teenagers in the women's game.
