NEW YORK (AP) — The Latest on the US Open (all times local):
Roger Federer finally got broken — twice, actually — but was in control pretty much the entire way en route to the fourth round of the U.S. Open for the 15th consecutive year.
The No. 2-seeded Federer beat No. 29 Philipp Kohlschreiber of Germany 6-3, 6-4, 6-4 on Saturday.
Federer has won each of his nine sets through three matches, dropping only a total of 20 games so far.
The 17-time major champion, who won the U.S. Open five times in a row from 2004-08, entered the match against Kohlschreiber having won 72 straight service games, including all 23 in New York.
Kohlschreiber broke Federer once in each of the last two sets — and Federer broke right back each time.
Federer, now 10-0 against Kohlschreiber, faces 13th-seeded John Isner of the United States for a spot in the quarterfinals.
British qualifier Johanna Konta ran her winning streak to 16 matches by beating 18th-seeded Andrea Petkovic of Germany 7-6 (2) 6-3 to reach the fourth round of a Grand Slam tournament for the first time.
It was an impressive follow-up for Konta, whose previous match was a 7-6 (4), 6-7 (4) 6-2 victory over Wimbledon runner-up Garbine Muguruza that lasted 3 hours, 23 minutes, the longest U.S. Open women’s match since the introduction of the tiebreaker in 1970.
Konta’s winning streak includes three main-draw U.S. Open matches, three qualifying matches at Flushing Meadows, and nine matches at low-tier events.
Petkovic appeared bothered by the heat during the second set. Trailing 3-0, 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.
No. 5 seed Petra Kvitova has moved into the fourth round of the U.S. Open with a 6-2, 6-1 win against 32nd-seeded Anna Karolina Schmiedlova of Slovakia.
It will be two-time Wimbledon champion Kvitova’s third appearance in the fourth round at Flushing Meadows, but she is 0-2 at that stage.
Kvitova never presented Schmiedlova with a break opportunity in the 66-minute match. The Czech star converted five of her nine break chances.
