Overview
- Coco Gauff beat Marta Kostyuk 6-4, 7-5 but was eliminated when Jessica Pegula defeated Linda Noskova later the same day, which gave Pegula the final semi‑final spot.
- Linda Noskova had already secured a semi‑final berth with a 2-0 group record, so Pegula only needed a win to clinch second place and deny Gauff advancement.
- Marta Kostyuk entered the event as the first alternate after Elena Rybakina withdrew with illness and finished Group 1 without a win while carrying a wrist problem.
- Gauff staged a six‑game comeback from 5-1 in the second set and received on‑court treatment for back tightness during the match, which she said affected her serve and motion.
- Organisers relocated the 2026 WTA Finals from Riyadh to Indian Wells and have confirmed a multi‑year move to Charlotte starting in 2027, a change that altered logistics and the tournament’s context this week.
