Grand Slam champion

Serena Williams has eliminated No. 2 seed Anett Kontaveit 7-6 (4), 2-6, 6-2 in the U.S. Open’s second round to ensure that the 23-time Grand Slam champion will play at least one more singles match.

Serena Williams' first opponent at what she has indicated will be her last U.S. Open — and, indeed, the last tournament of her career — is unseeded Danka Kovinic.
