MELBOURNE, Australia — Within an hour of her third-round loss at the Australian Open, defending champion Naomi Osaka had consigned it to the past.

It’s part of her new resolution for 2022. No dwelling on what’s already happened.

Osaka had two match points against 60th-ranked Amanda Anisimova in the third set Friday, and she missed two backhands.

Anisimova held serve to force a tiebreaker, which she dominated, and finished with an ace for a 4-6, 6-3, 7-6 (5) comeback victory over the four-time major champion.
