Naomi Osaka vs. Sorana Cirstea: History and How They Got Here

Naomi Osaka

Naomi Osaka hasn't made it to the final of a Grand Slam since she won the 2021 Australian Open. She showed a flash of her former greatness at last year's U.S. Open when she made it to the semifinals before being eliminated by Amanda Anisimova.

Osaka fans have to be a little bit concerned that it took her three sets to get past Antonia Ruzic in the opening round, including barely squeaking by her by a score of 6-4 in the third set.

Sorana Cirstea

Sorana Cirstea is at the back end of her career, but is looking to make one more deep run at a Grand Slam. The 35-year-old Romanian has made it to the quarterfinals of a Grand Slam twice in her career, at the French Open in 2009 and the U.S. Open in 2023. She has never made it to the quarterfinals of the Australian Open. The furthest she's made it at this tournament was a fourth-round appearance in both 2017 and 2022.

She defeated Eva Lys in three sets in the opening round.

Naomi Osaka vs. Sorana Cirstea Best Bet to Place

These two competitors have faced each other once before, but it was back in 2015 in the qualifying for Wimbledon. Cirstea got the better of Osaka, winning 2-6, 6-1, 6-4.

It's tough to trust Osaka when it comes to betting on this match. She went 1-1 at the United Cup earlier this month, losing to Maria Sakkari. Her flash in the pan at the U.S. Open was then followed up by going 3-3 in her final six matches of 2025, including conceding in her match against Jagueline Cristian in October.

We know Osaka has the talent, but the psychological aspect of her game is unpredictable at best.

Meanwhile, Cirstea seems to be in phenomenal form. She made it to the Round of 16 before losing to the No. 1-ranked women's tennis player, Aryna Sabalenka, at the Brisbane International earlier this month.

I'm going to back the Romanian as an underdog in Round 2.
