Defending champion Iga Swiatek said she would needed to have been "pretty naive" to think she could beat Naomi Osaka after falling match point down before recovering to win a French Open thriller on Wednesday. The world number one fought back from the brink of defeat to outlast Osaka 7-6 (7/1), 1-6, 7-5 and keep her bid for a third successive Roland Garros title on track. Swiatek trailed 5-2 in the deciding set against fellow four-time Grand Slam champion Osaka, saving a match point on her opponent's serve and winning the final five games to avoid a shock early exit.
