Kostyuk vs Hunter Prediction 30 August 2026
🔊 The first round of the 2026 US Open brings together two players from very different ends of the rankings. Marta Kostyuk will look to assert her status as a top-level player against Storm Hunter, who arrives on the back of a strong qualifying run. It shapes up as a classic contest of power and consistency against doubles experience and fighting spirit. For both players, New York offers a real chance to make a statement as the season draws to a close.
Head-to-Head
📊 The two players have met once before, with Marta Kostyuk taking the win back in 2020 - too long ago to carry much weight here.
Head-to-head statistics Kostyuk - Hunter



Marta Kostyuk Player Overview
Marta Kostyuk arrives at this tournament in solid form - seven wins from her last ten matches, including strong results against high-quality opponents at major events. In her most recent run she beat Sloane Stephens and Mirra Andreeva before falling to Coco Gauff in the quarter-finals. Kostyuk holds serve in around 65% of her service games, and her overall set-winning percentage stands at 65%. Her first-serve percentage is just 53%, which leaves room for opponents to apply pressure on return. Her double-fault rate is above average at 7%, though that is offset by a break-point conversion rate of 59%. That combination of strengths suggests she can maintain control of a match even when her level dips.
Match Results: Marta Kostyuk

Storm Sanders Player Overview
Hunter came through three qualifying matches at the US Open without dropping a match, and has won six of her last ten overall - solid form heading into the main draw. She holds serve in around 69% of her service games, marginally ahead of Kostyuk in that department. Her matches average 25.5 games, reflecting a tendency towards extended sets and an ability to stay competitive even against higher-ranked opponents. Her break-point conversion rate stands at 48%, and her first-serve percentage is a consistent 70%. Despite her lower ranking and a lack of notable results at the bigger tournaments this season, Hunter has shown she can make life difficult for opponents through tight, disciplined play - and she carries real confidence from her qualifying run.
Match Results: Storm Sanders
Key factors
- Hunter has covered the +5.5 games handicap in nine of her last matches.
- The average number of games in Hunter's matches is 25.5, suggesting lengthy sets.
- Both players have won more than half their games and sets in recent matches.
- The gap in ranking and quality is significant, but Hunter has found good form through qualifying.
- Kostyuk won their only previous meeting, though that match was in 2020 and has little bearing on their current levels.
Expected scenario
Kostyuk enters the match as the clear favourite, but Hunter's record against the +5.5 games handicap and her average game counts suggest the underdog can win enough games to cover. A third set is a moderate possibility; a completely one-sided result looks unlikely given how both players have tended to perform in recent matches. That makes Hunter - Games Handicap +5.5 our pick.
⭐ Editor's Pick
Marta Kostyuk is in strong form and holds a clear ranking advantage, yet Storm Hunter has shown she can compete for every game even against top seeds. The Australian's high hold percentage, combined with a run of covering positive handicaps, makes this a logical first-round US Open pick - Storm Hunter - Games Handicap +5.5.
