Petra Kvitova breezes into last 16

Petra Kvitova has eased past Anna Karolina Schmiedlova to secure her place in the last 16 of the US Open.

The fifth seed required just 65 minutes to register a 6-2 6-1 victory over her Slovakian opponent.

Kvitova has begun the tournament well, picking up back-to-back wins in straight sets against Laura Siegemund and Nicole Gibbs, and she wasted little time in imposing herself against Schmiedlova, who had her serve broken twice during a one-sided first set.

Schmiedlova, the 32nd seed, took the opening game of the second, but that was as good as it got for the 20-year-old, who saw Kvitova reel off six straight games to confirm her spot in the fourth round.

The two-time Wimbledon winner will now play either Andrea Petkovic or Johanna Konta for a place in the quarter-finals.
