• 🏟️ Slam record: Wimbledon 3R earlier this year (best career Slam result).
• ⚠️ Form: Up-and-down season — only two events with back-to-back wins (Merida QF, Wimbledon R3). Struggles vs top-30 consistency.

Marta Kostyuk (No. 28, age 23)

• 🇺🇦 Aggressive baseliner with elite shotmaking upside.
• 📊 2025 record: 22–17 overall, 15–11 on hard.

🔍 Match Breakdown

Head-to-Head: Kostyuk leads 1–0 (Doha 2025, 6–3, 6–3). Saved 10/12 break points in that win.

Sonmez’s path: Relies on counterpunching and rally tolerance. Needs to extend points and test Kostyuk’s physical durability.

Kostyuk’s path: Plays proactive, dictating with pace and sharp angles. If wrist holds up, she can disrupt Sonmez’s rhythm consistently.

X-factor: Sonmez has nothing to lose, already equaling her best Slam result. Kostyuk’s fitness is the only variable that could tilt the matchup.

🔮 Prediction

Sonmez has taken a big step forward in 2025, but Kostyuk’s higher baseline level and recent H2H win tilt this heavily her way. Unless the wrist injury resurfaces, the Ukrainian should progress smoothly.

Pick: Kostyuk in 2 sets. (If the wrist flares, Sonmez has grit to stretch it into a decider.)
