Canadian teenager Bianca Andreescu reached the fourth round of a Grand Slam for the first time with a straight-sets victory over former world No 1 Caroline Wozniacki at the US Open.
The 19-year-old, who has won two titles in her breakout season, defeated the 2009 finalist 6-4 6-4 on the Arthur Ashe Stadium.
Andreescu is yet to lose a set on her main draw debut at Flushing Meadows and will face American qualifier Taylor Townsend for a place in the quarter-finals.
The 15th seed appeared in total command, leading by a set and 3-0 in the second set, but there was then a series of breaks before she held her nerve to overcome the Dane in one hour and 32 minutes.
Townsend, who knocked out Wimbledon champion Simona Halep in the second round, continued her impressive run with victory against Romanian Sorana Cirstea.
The 23-year-old - ranked world No 116 - defeated Cirstea 7-5 6-2 to also reach the second week of a Grand Slam for the first time.
Julia Goerges matched her best performance in New York as the German pulled off a surprise victory against seventh-seed Kiki Bertens.
The German, seeded 26th, sealed a 6-2 6-3 victory on her fifth match point.
Goerges will next face 23rd-seed Donna Vekic after the 23-year-old Croatian eased to a 6-4 6-1 win against Yulia Putintseva of Kazakhstan.
American Kristie Ahn, world No 141, reached the second week of a Grand Slam for the first time with a 6-3 7-5 victory against Jelena Ostapenko.
The 27-year-old made her main draw debut at Flushing Meadows in 2008 but only secured her first victory in the first round earlier this week.
Elise Mertens advanced to the last 16 for the second year in a row with a 6-3 6-3 win against Andrea Petkovic.
Mertens, who was a semi-finalist at last year's Australian Open, hit seven aces and 26 winners to ease past the German who had defeated Petra Kvitova in the previous round.
Meanwhile, Belinda Bencic advanced with a walkover after Anett Kontaveit withdrew from singles play with an acute viral illness.
The 13th seed from Switzerland will meet either defending champion Naomi Osaka or American teenager Cori Gauff who clash in the night session.
