France's Lois Boisson, a surprise French Open semifinalist, has jumped 296 places in the latest WTA rankings released Monday to a career-high 65.
Aryna Sabalenka and Coco Gauff hold the top two spots after their run to the finals in Paris where American Gauff defeated world No 1 Sabalenka in three sets.
Boisson received a wildcard entry a year after undergoing surgery on her left knee, playing her first Grand Slam ranked 361th in the world.
The 22-year-old beat world No 3 Jessica Pegula and sixth ranked Mirra Andreeva before falling to Gauff in the semifinals.
Iga Swiatek, the defending three-time French Open champion, falls two places to seventh after her semifinal defeat to Sabalenka.
China's Zheng Qinwen moves up to fifth after reaching the quarterfinals in Paris where she won Olympic gold last year.
