Marta Kostyuk, with a 26–18 win-loss record so far in 2025, has shown resilience and determination. However, her 66.6% first serve win rate and 38.9% return game win rate indicate areas where improvement is needed to compete at the highest level. While the Ukrainian possesses a powerful groundstroke game, her inconsistency on serve and return games may pose challenges against top-tier opponents.
Considering Pegula’s superior service statistics and consistent performance on hard courts, she is favored to advance in this encounter. However, Kostyuk’s aggressive baseline game and potential to capitalize on the American’s occasional lapses could make for a competitive match. Overall, Pegula’s experience and current form make her the heavy favorite to win the match but Kostyuk’s unpredictability adds an element of intrigue to the matchup.
Prediction: Pegula to win in three sets
