Kostyuk advanced with a straight-sets second-round win over Parry and a gritty three-set quarterfinal triumph over Ann Li (6-0, 6-7(4), 6-3), showcasing baseline power suited to the surface. Maria notched straight-set victories, including her first Top 100 win of 2026 against Jacquemot and a 7-6(5), 6-2 defeat of Shymanovich, leveraging slice and dropshots. No injury concerns reported ahead of the April 18 matchup; Kostyuk's youth and form give her stylistic matchup advantages.
