NEW YORK — No. 5 seed Petra Kvitova moved into the fourth round of the US Open Saturday with a 6-2, 6-1 win against 32nd-seeded Anna Karolina Schmiedlova of Slovakia. It will be Kvitova's third appearance in the fourth round at Flushing Meadows. The two-time Wimbledon champion also accomplished the feat in 2009 and 2012, but she has never made it to the semifinals in the last Grand Slam of the year. Kvitova never presented Schmiedlova with a break opportunity in the 66-minute match. The Czech star converted five of her nine break chances. British qualifier Johanna Konta beat No. 18 seed Andrea Petkovic of Germany 7-6 (2), 6-3 to reach the fourth round of a Grand Slam for the first time. Petkovic appeared bothered by the heat during the second set. Trailing Konta 0-3, she had the trainer on court taking her blood pressure and pulse. The 97th-ranked Konta needed six match points to finish the victory in 1 hour, 56 minutes. Konta failed to take advantage of three match points in the 18-point seventh game, allowing Petkovic to break her serve. Two games later, Konta secured the win on her third match point of the ninth game when Petkovic sailed a forehand long. — AP
