Osaka appears to be back at her best again

It's first time she has made it this far at a grand slam since the Aus Open in 2021

Once Naomi Osaka is in the quarterfinals of a Grand Slam tournament, look out.

For a while, it was getting there that was the problem.

Right now, Osaka appears to be back at her best, and she most definitively is back at that stage of a major, getting ready to face Karolina Muchova at the US Open today for a spot in the semifinals.

It's the first time Osaka who has been ranked No 1 and now is seeded No 23 has made it this far at one of the four most important events in tennis since the Australian Open in early 2021. That was also the last time she won a Slam trophy.
