NEW YORK — The latest on the U.S. Open (all times local):
12:40 p.m.:
Daria Kasatkina is a lucky winner.
The 133rd-ranked Russian teen lost in U.S. Open qualifying Friday, but when third-seeded Maria Sharapova withdrew Sunday because of an injury, Kasatkina was suddenly in her first Grand Slam main draw as a "lucky loser."
She proceeded to upset 38th-ranked Daria Gavrilova in the first round the next day, then won again Wednesday to become the first lucky loser to reach the women's third round since 1993.
Kasatkina defeated 79th-ranked Ana Konjuh 6-4, 6-4.
