Jannik Sinner breezes past Alex Popyrin, Iga Swiatek takes down Lamens

World number two Swiatek looked to be cruising as she led her Dutch opponent by a set and a break but stumbled before eventually seeing off the 66th-ranked Lamens 6-1, 4-6, 6-4.

"It wasn't an easy match. I did some mistakes," said Swiatek.

"I felt like it depended on me and if I made mistakes or not, sometimes I did. I probably got a little tight in the second set.

"But the third set is a reset. You've got to start from the beginning and I knew I could play a little more precisely, so I just tried to do that."
