Aryna Sabalenka of Belarus celebrates beating Serbia's Olga Danilovic during their third round match of the French Tennis Open, at the Roland-Garros stadium, in Paris.
Defending champion Iga Swiatek joined No. 1-ranked Aryna Sabalenka in the fourth round of the French Open on Friday and neither player has dropped a set. Sabalenka, a three-time Grand Slam winner who has only once reached the semifinals at Roland-Garros, beat Olga Danilovic 6-2, 6-3 on Court Philippe-Chatrier, where the hot weather contrasted with previous days. Swiatek, who has won four of her five major titles at Roland-Garros, defeated Jaqueline Cristian 6-2, 7-5 on Court Suzanne-Lenglen to extend her French Open winning streak to 23 matches. A second set lasting 1 hour, 16 minutes, tested the Pole, who yelled in relief after winning on her second match point. Swiatek had 20 winners and 21 unforced errors.
