French Open champion Barbora Krejcikova’s twin titles at Roland Garros earned jumps in the WTA rankings to No. 15 in singles and No. 1 in doubles.

The women’s and men’s rankings released Monday determine which players are eligible to compete at the Tokyo Olympics, which start next month. Each country can send as many as four women and four men in singles, and 17-year-old Coco Gauff rose two spots to a career-best No. 23, which makes her the fourth-highest woman from the United States.

Gauff is behind No. 5 Sofia Kenin, No 8 Serena Williams and No. 14 Jennifer Brady. Jessica Pegula is No. 26, with Madison Keys at No. 28.

The WTA Top 10 didn’t change, including Ash Barty at No. 1 and Naomi Osaka at No. 2.

Novak Djokovic remained at No. 1 in the ATP rankings after claiming his second French Open title — and 19th at a major tournament — by beating Stefanos Tsitsipas 6-7 (6), 2-6, 6-3, 6-2, 6-4 in Sunday’s final.
