 Australia — Defending champion Naomi Osaka didn’t make it to a much-anticipated fourth-round contest against top-ranked Ash Barty at the Australian Open.

Amanda Anisimova, a 20-year-old American ranked 60th in the world, ensured that so-called final-before-the-final won’t happen when she beat the four-time major champion 4-6, 6-3, 7-6 (5) Friday.

I knew I had to be playing sharp if I wanted to give myself a chance,” said Anisimova

 who took out Olympic champion Belinda Bencic in the second round and then accounted for the 2021 Australian Open champion.

After losing the first set, Anisimova knew she needed to get more aggressive or she would be out of the tournament

Anisimova saved two match points in the third set, serving to stay in the match, and ended it with an ace. She hit 46 winners to Osaka’s 21.
