Naomi Osaka came close to dumping top-seeded Iga Swiatek out of the French Open on Wednesday, and the former world No. 1 said she was sure the best display of her comeback season could spur her to climb into the Top 5 again.

The Japanese superstar led 5-2 in the final set of a pulsating second-round clash and even had a match point.

But Swiatek, the defending champion, staged an impressive rally for a 7-6 (7-1), 1-6, 7-5 win that kept her on course for her fourth title in Paris and fifth Grand Slam crown.
