The Latest: Rain delaying most matches at US Open

NEW YORK (AP) — The Latest on the U.S. Open tennis tournament (all times local):

11:55 a.m.

Play is being delayed on all the outside courts at the U.S. Open because of rain.

Tournament officials announced that play would not begin before 12:30 p.m. on any of the outside courts.

So the only match going on at that point was a fourth-round women’s singles meeting between No. 23 Donna Vekic and 26th-seeded Julia Goerges at Louis Armstrong Stadium, which has a retractable roof. Play was scheduled to begin on Arthur Ashe Stadium, the other roofed stadium, at noon with top-ranked Naomi Osaka facing No. 13 Belinda Bencic.

After an easy first week at the U.S. Open, Rafael Nadal figures to have a challenge in the fourth round.

The No. 2 seed faces No. 22 Marin Cilic in a matchup of past champions, with the winner getting a spot in the quarterfinals.

Nadal has played just two matches and spent a little more than four hours on the court, getting a walkover in the second round and winning twice in straight sets.

Cilic, the 2014 champion, hopes to improve to 6-0 in fourth-round matches at Flushing Meadows.

Top-ranked Naomi Osaka is also in action, while American teenagers Coco Gauff and Caty McNally try to remain unbeaten in doubles. Taylor Townsend and Kristie Ahn of the U.S. hope to extend their longest runs in Grand Slam tournaments.
