Anhelina Kalinina defeated pre-match favourite Mirra Andreeva 6–4, 7–5 in the quarter-final of the WTA 250 event in Rouen on clay on 19 April 2024, an upset victory that defied the betting odds. Kalinina, positioned as the underdog at 2.45, dismantled the favoured Andreeva, who entered at 1.63, to advance through the draw. The Ukrainian secured both sets with a break of serve in each, maintaining composure in the second set where Andreeva mounted some resistance but ultimately could not recover. The result marks a significant scalp for Kalinina on the clay court circuit and represents a notable setback for the younger Andreeva's momentum in the tournament.
