World number two Iga Swiatek got her bid for a second US Open title off to a winning start with a comfortable straight-set victory over Colombia's Emiliana Arango.
The Pole, who won a maiden Wimbledon title last month and is the favourite to add a second title at Flushing Meadows to her 2022 triumph, cruised to a 6-1 6-2 victory on Arthur Ashe Stadium.
Swiatek hit 26 winners to world number 84 Arango's five and won 76% of her points on serve without facing a break point.
"It felt great - first matches are not easy to get used to the rhythm and it was a solid match," she said.
