Daria Kasatkina vs. Katerina Siniakova Head-to-Head, Preview, Prediction, and Betting Odds for WTA Korea Open 2025 Round of 16

Fourth seed Kasatkina meets dangerous Siniakova in round two at the Korea Open.

Fourth seed Daria Kasatkina is set to take on qualifier Katerina Siniakova in the second round of the Korea Open 2025. Kasatkina entered with a first-round bye, while Siniakova opened her campaign by easing past So-hyun Park in straight sets.

Kasatkina’s season has been modest by her standards. The Russian reached the quarterfinals in Adelaide and made fourth-round runs at both the Australian Open and Roland Garros but struggled to string together consistency elsewhere, often falling before the third round. Most recently, she exited in the third round of the US Open, edged by Naomi Osaka in three sets. Across 40 matches this year, Kasatkina has delivered 67 aces, won 60.2% of her first serves, claimed 47.7% of return points, and converted 47.9% of break points.

Siniakova, a 10-time doubles Grand Slam champion, continues to search for a breakthrough season in singles. The Czech has shown glimpses of form, highlighted by a WTA 125 title in Warsaw over Viktorija Golubic, semifinal runs at the Winner Open, and quarterfinal runs in Lleida and Prague. But consistency has been elusive, with early exits the more common trend. Most recently, she fell in the opening round at Guadalajara to Storm Hunter in three sets. In 29 matches this year, Siniakova has tallied 62 aces, winning 62.9% of first serves, 43.4% of return points, and 41.9% of break points converted.

Daria Kasatkina vs. Katerina Siniakova Head-to-Head Record

Daria Kasatkina leads the head-to-head 6-1 against Katerina Siniakova, but the rivalry has been anything but routine. Only once has Kasatkina won in straight sets, back in Rome 2020, while most of her victories have required either three sets or gritty comebacks.

The other exception came at Indian Wells 2018, where Siniakova retired with a right wrist injury. Kasatkina dominated their early meetings, taking the first four and the last two, while Siniakova’s lone breakthrough came on clay in Hamburg 2022. Their most recent clash was at Roland Garros earlier this season, with Kasatkina once again prevailing.

Daria Kasatkina vs. Katerina Siniakova Prediction

Kasatkina’s consistency and defensive skills give her the edge, but Siniakova’s all-court versatility and recent flashes of form could turn this into a battle that goes the distance.

What an arm wrestle! 💪

My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
