Mirra Andreeva vs Marta Kostyuk WTA Cincinnati Tips, Prediction & Live Stream

It should be a cracking contest as these two resume hostilities with a spot in the Cincinnati quarter-finals on the line. Kostyuk won their first two meetings this season in Brisbane and Madrid, but Andreeva prevailed in the big dance, beating the Ukrainian on her way to maiden Grand Slam glory at the French Open.

Somewhat predictably, Andreeva has struggled since that breakthrough and this tournament in Cincinnati marks the first time she's won back-to-back matches. Kostyuk also hasn't been at her best lately, but she's battled through two matches in Cincinnati over Sofia Kenin and Sloane Stephens, where she needed 24+ games in both.

So this is a big match for both as they look to continue building momentum ahead of the US Open. With Andreeva restoring some confidence and Kostyuk remaining at an overall high level, this looks like it's shaping as a tight contest and not a lot is splitting them.

From what I've seen so far in Cincinnati, Andreeva looks in marginally better form, so the fifth seed is backed in a contest that goes Over 21.5 total games.

Mirra Andreeva Form Analysis

2026 WTA Record: 40-12
WTA Cincinnati Record: 5-1
Current Ranking: No. 6
Career-High Ranking: No. 5 (2025)

It's been a strong overall season for Andreeva - she's won 40 of her 52 matches and most importantly, picked up her first major title at Roland Garros.

Although she picked up the title in Adelaide to start the season, clay is where Andreeva has mainly flourished so far in 2026 - she also won the Linz silverware and finished runner-up in Madrid before her Grand Slam breakthrough in Paris.

The 19-year-old struggled initially struggled to back up that triumph, winning just two matches across Bad Homburg, Wimbledon and Toronto, where she was eliminated by Leylah Fernandez.

Andreeva has returned to a solid level in Cincinnati, a tournament she is playing for just the second time after a debut quarter-final run in 2024. Andreeva crushed Oleksandra Oliynykova 6-0 6-1 in her opener before closing out Janice Tjen 6-1 7-6(5).

Marta Kostyuk Form Analysis

2026 WTA Record: 32-7
WTA Cincinnati Record: 6-3
Current Ranking: No. 11
Career-High Ranking: No. 11 (July 2026)

Kostyuk has enjoyed a breakthrough campaign and looks well on track to establish herself inside the world's top 10 in the near future.

After an ankle injury disrupted the early part of her season, the Ukrainian has been one of the WTA Tour's standout performers. She reeled off a 16-match winning streak on clay, capturing titles in Rouen and Madrid before advancing to the semi-finals at Roland Garros.

The 24-year-old carried that momentum into the grass season, reaching another Grand Slam semi-final at Wimbledon, although she fell short against eventual champion Linda Nosková. Returning to hard courts in Montreal, Kostyuk's run ended in the fourth round as she was beaten in three sets by eventual champion Iga Swiatek.

It hasn't been the most convincing of Cincinnati campaigns so far for Kostyuk - she managed to edge out World No. 115 Sofia Kenin 4-6, 6-3, 7-5 in her opening match before squeaking past No. 240 Sloane Stephens 7-5 7-5.
