Naomi Osaka’s Australian Open championship has allowed her to move up to No. 2 in the WTA rankings. Men’s finalist Daniil Medvedev rose to a career-best No. 3 behind winner Novak Djokovic on the ATP list. Women’s runner-up Jennifer Brady jumped 11 spots to No. 13. This is the 25-year-old American’s first time inside the Top 20. Aslan Karatsev’s historic run from qualifying to the final four vaulted him 72 places from 114th to 42nd. He is the first man in the professional era to reach the semifinals in his debut in the main draw of a major tournament. Rafael Nadal stayed at No. 2 after losing in the quarterfinals at Melbourne Park, as did women’s No. 1 Ash Barty.
