World No. 28 Marta Kostyuk is set to face off against World No. 48, Katie Boulter, in the US Open round 1. While Boulter has a win over Kostyuk, there’s still a cause for worry for the British star. With BetMGM presenting you with the most accurate betting odds for the 2025 US Open, here’s a preview for this great clash.

Marta Kostyuk is coming off a disappointing Cincinnati Open performance. However, overall, Kostyuk’s year has been quite strong. She’s been 21-17 this year but, more importantly, has gone 14-10 on the hard court across various events. Add to that, Kostyuk has converted 47.9% of her breakpoints on the hard court this year. As a result, Kostyuk is entering the US Open on a relatively stronger footing.

Katie Boulter couldn’t make it past the round of 128 in the Cincinnati Open. 2025 hasn’t been particularly kind to Boulter, who has barely managed to have a winning record (17-15). However, the real cause of worry comes on hard courts, where Boulter has a disappointing 3-7 record. But her one key advantage could be the success Boulter has had in converting break points (54.3%). It is to be seen how big an advantage that proves to be for the 29-year-old tennis star.

Marta Kostyuk vs. Katie Boulter Head-to-Head

Katie Boulter leads Marta Kostyuk 1-0 in their head-to-head contests.

The two have faced each other only once, and it was in the 2024 San Diego Open final. While Kostyuk took the first set, Boulter ended up mounting an impressive comeback to win the match in 3 sets. The fact that this match was also played on the hard court makes it rather interesting. Could something similar happen again?

Marta Kostyuk vs Katie Boulter Match Prediction

Both Kostyuk and Boulter are aiming to erase the memories of their cold performances in the last few weeks. However, while Boulter holds a win over Kostyuk, she hasn’t been effective at all on the hard courts. The bigger worry for her? Kostyuk has exactly the opposite of that going on in her game. The Ukrainian has been quite dominant on this surface, and that could lead to an easy win for Kostyuk.
