It was a particularly poignant day on Court Philippe-Chatrier as Marta Kostyuk moved past compatriot Elina Svitolina 6-3, 2-6, 6-2 to book a maiden Grand Slam semifinal on Tuesday.
The pair are friends, title rivals and national sporting icons, and this was the first time in the Open era that two women representing Ukraine had gone head to head in the quarterfinals of a singles major.
Madrid champion Kostyuk arrived on court boosted by a 16-match winning streak on clay, whereas Rome champion Svitolina was riding a wave of 10 consecutive clay-court victories. Something had to give and it was fitting this duel went to a deciding set.
