Muguruza is eliminated from the Australian Open as Garcia and Sabalenka record opening victories.

Aryna Sabalenka led the WTA circuit in double faults in 2022, but she has started 2023 off without a loss thanks to a crucial serve on Tuesday in Melbourne. After a straightforward victory over Tereza Martincova of the Czech Republic in straight sets, the Adelaide 1 champion advanced to the second round in Melbourne. Caroline Garcia defeated Katherine Sebov 6-3, 6-0 to advance as well.
