Britain’s Johanna Konta suffered a shock first-round defeat against unseeded Serbian Aleksandra Krunic at the US Open.
Konta, seeded seven, was among the favourites for the title and one of eight women who could have ended the tournament as world number one.
However, a first-serve percentage of just 45% allowed the clean-hitting Krunic to attack off the return, and the world number 78 fought back for a 4-6 6-3 6-4 victory.
Kyle Edmund and Cameron Norrie had earlier claimed first-round victories in the men’s singles, but Heather Watson was beaten in the women’s singles.
Following two days after Andy Murray’s withdrawal with a hip injury, Konta’s defeat means neither British number one player survived beyond the first afternoon.
