    Ann Li Player Overview

    Ann Li has found her rhythm on clay, even though her winning streak only began in Rouen. Her journey to the quarterfinals has been anything but easy, with two matches against Daria Kasatkina and Kamilla Rakhimova going the distance. Three-setters are not uncommon for Ann, as four of her last five encounters have stretched to three sets. A crucial aspect of Ann's game is her powerful serve; she averages more aces per match (6.6) than many of her peers at this level.

    👀 Expected Match Scenario

    Ann Li is likely to rely on her aggressive serve and quick rallies. The American often scores with aces, aiming to avoid prolonged exchanges. However, her matches tend to be lengthy as she knows how to stay in her opponents' games. Marta Kostyuk will probably aim to control the rallies from the baseline. Yet, even from there, the Ukrainian can unleash powerful winners from almost any position.

    The key factor in this encounter could be Kostyuk's mental resilience in the later stages of tournaments. Despite her good current form, she sometimes struggles to maintain a consistent level in quarterfinals. The main question is whether Ann can capitalize on potential dips in her opponent's game. Considering their previous head-to-heads have been fiercely contested, the upcoming match also promises to be a tightly fought battle.

    ⭐ Editor's Prediction

    Marta Kostyuk and Ann Li are gearing up for a tense battle on the clay court in Rouen. Considering recent performances, Marta showcases more consistent play with a streak of three victories, but she often struggles when reaching the later stages of major tournaments. The American, despite her less consistent form, performs well against seeded players in clay competitions, winning 6 out of her last 10 encounters against them. Additionally, all head-to-head meetings between these players have been closely contested. We expect a similar scenario this time around. Our prediction: total games over 19.5.
