The player who went all the way at this event in 2017 will be in action on Wednesday, when Sloane Stephens looks to relive her glory days. The American competitor is up against current world number 11 Marta Kostyuk, who this season has reached the semi-finals of both the French Open and Wimbledon. She's a serious player, that's for sure.
These two players recently clashed in Cincinnati, where Marta Kostyuk won in straight sets, which is part of the reason why she's such a strong favorite here. However, is the early market paying too much attention to the bare result? Sure, the Ukrainian won in straight sets, but it wasn't her easiest win, coming out on top 7-5, 7-5. On that evidence, Sloane Stephens can certainly push Kostyuk more than early odds suggest.

Our Marta Kostyuk vs Sloane Stephens Prediction
Marta Kostyuk is not easy to face, but she's never been beyond the fourth round at Flushing Meadows, which is significant given that she's reached the quarters or better at every other slam. This tells us that she may not be at her best under the US Open conditions, so we shouldn't be too surprised if someone like Sloane Stephens, who does love these conditions, gives the Ukrainian plenty to think about.
Sloane Stephens improving slightly on that recent effort against Kostyuk is far from out of the question. After all, she's a former US Open winner, who knows how to raise her game at Flushing Meadows. Regardless of what happens, everything points towards the US player having a better chance of avoiding a straight-set defeat than early market indicates.
Our Marta Kostyuk vs Sloane Stephens Pick: Sloane Stephens +1.5 Set Handicap.
