During the 2023 French Open, Sabalenka played against Marta Kostyuk and Elina Svitolina from Ukraine, and both players refused to shake the Belarusian's hand after the match.Sabalenka was also asked her opinion of Belarus president Alexander Lukashenko during one of her press conferences, which prompted her to take a mental health break from pressers over the next couple of days.Pam Shriver@PHShriverTrying to win a major is extremely hard and for Sabalenka she tried to win her second major with a ton of off court turmoil swirling. Could this have contributed to the collapse? The collapse indicted not enough in reserves for Sabalenka.362Trying to win a major is extremely hard and for Sabalenka she tried to win her second major with a ton of off court turmoil swirling.
