Marta Kostyuk vs Sloane Stephens WTA Cincinnati Tips, Prediction & Live Stream
Sloane Stephens is coming off her biggest win in over two years and has nothing to lose against Marta Kostyuk, who while enjoying a stellar season, hasn't been entirely convincing against players outside the top 100. The 2017 US Open champion has restored some confidence and can cover a big +5.5 line when the pair square off in the third round of the Cincinnati Open on Tuesday.
At her best, Stephens was arguably the best athlete on the WTA Tour - her retrieving skills were incredible and her ability to absorb and redirect pace was sublime. However, the American's movement took a big hit with a serious stress fracture injury to her right foot, which limited her to just five matches last year as she transitioned into the media world while undergoing a long rehab program.
Stephens is back playing pain-free and her hard work has paid off, earning a straight sets win over Anastasia Potapova in the second round of Cincinnati - her first top 30 scalp since Madrid 2024.
With nothing to lose and looking dangerous again, I think Stephens can cover with a +5.5 start here.
Kostyuk has been one of the standout players on tour in 2026, compiling a 31-7 record and going deep in pretty much every tournament she's entered. However, the Ukrainian hasn't been at her dominant best lately and needed three sets to overcome an out-of-form Sofia Kenin in her Cincy opener.
The pair have also never played before, so there's an element of unknown surrounding the match too. It's a big line and if Stephens can reproduce her level from the win over Potapova, she should have a good chance to cover.

Marta Kostyuk Form Analysis
- 2026 WTA Record: 31-7
- WTA Cincinnati Record: 5-3
- Current Ranking: No. 11
- Career-High Ranking: No. 11 (July 2026)
It's been an incredible season for Kostyuk and she should be cracking the top 10 sooner rather than later.
After an ankle injury affected her start to the year, Kostyuk has been one of the form players on tour, compiling a 16-match winning streak on clay, which yielded titles in Rouen and Madrid, along with a semi-final run at Roland Garros.
Kostyuk backed it up with another semi-final at Wimbledon, but would have been disappointed with her defeat to eventual champion Linda Noskova. The 24-year-old returned to action in Montreal, where she was upstaged in three sets by resurgent eventual champion Iga Swiatek in the R16.
It wasn't the cleanest start to Cincinnati for Kostyuk as she edged out World No. 115 Sofia Kenin 4-6 6-3 7-5 in her opening match.
Sloane Stephens Form Analysis
- 2026 WTA Record: 6-10
- WTA Cincinnati Record: 19-12
- Current Ranking: No. 240
- Career-High Ranking: No. 3 (2018)
It's been a rough last few years for Stephens, who appeared on the brink of retirement after suffering that serious stress fracture injury to her foot.
Opting against surgery and instead undergoing a lengthy rehab program, Stephens has returned to tour this year and slowly but surely is regaining a solid level.
Stephens qualified for both the Australian Open and Roland Garros before compiling a decent little summer coming into this clash.
Indeed, the 33-year-old won a round at both Memphis and Toronto before producing some great tennis to win back-to-back tour-level matches for the first time since 2024 in Cincinnati.
Stephens opened with a 7-5 6-3 win over Sinja Kraus before registering a commanding 6-2 6-4 victory over 24th seed Anastasia Potapova - her first top 30 win in 27 months.
