NEW YORK — Serena Williams could face Maria Sharapova for her second straight major semifinal as she seeks to complete the Grand Slam at the U.S. Open.
Thursday's draw filled the top-ranked Williams' quarter of the bracket with Americans, nine in all.
In the third round, Williams could face 29th-seeded Sloane Stephens, who beat her in the 2013 Australian Open and is coming off her first WTA title in Washington this month. Another up-and-coming U.S. player, 19th-seeded Madison Keys, could await in the fourth round.
And in the quarterfinals, one potential opponent is her sister, 23rd-seeded Venus Williams.
