World number one Iga Swiatek reached her second US Open quarter-final on Monday with a straight sets win over Liudmila Samonsova to stay on course for a sixth Grand Slam title.
Swiatek defeated her 16th-ranked Russian rival 6-4, 6-1, reeling off eight of the last nine games, and will take on American sixth seed Jessica Pegula for a place in the semi-finals.
Four-time French Open champion Swiatek won the US Open in 2022, beating Pegula on the way in a one-sided last-eight tie.
Pegula made the quarter-finals earlier Monday with a 6-4, 6-2 win over Russia's Diana Shnaider.
