Serena Williams tees up all-American clash with Sloane Stephens at US Open
Defending champion Serena Williams beat unseeded Yaroslava Shvedova of Kazakhstan 6-3, 6-1 to set up a fourth-round clash with fellow American Sloane Stephens.

Defending champion Serena Williams beat unseeded Yaroslava Shvedova of Kazakhstan 6-3, 6-1 to set up a fourth-round clash with fellow American Sloane Stephens.
Four-time US Open winner Williams grabbed the only service break of the first set in the sixth game and immediately seized the advantage by breaking the 78th-ranked Shvedova in the opening game of the second set and charged on to victory.
The routine win moved the world number one and top seed into the round of 16 against 20-year-old Stephens, who defeated Williams in the quarter-finals of this year's Australian Open.
The 15th-seeded Stephens defeated compatriot Jamie Hampton 6-1, 6-3 in her third-round match.
Williams, 31, was never really threatened by Shvedova, who had advanced to the third round with the loss of just six games.
The 25-year-old with the heavy, flat groundstrokes produced only three winners as she fell short of becoming the first woman representing Kazakhstan to reach the fourth round of the US Open.
