Great Britain's Johanna Konta has advanced to the fourth round of the US Open after recording a 6-2 6-1 victory over Switzerland's Belinda Bencic in New York on Friday afternoon.

Konta's tournament was in doubt when she collapsed in her second-round match with Tsvetana Pironkova on Wednesday after complaining of blurred vision and breathing issues.

However, there were no sign of the health concerns in her third-round match as the 25-year-old took the first set 6-2, before blowing away her opponent in impressive fashion to claim the second 6-1 in just 24 minutes.

Konta, who reached the fourth round of the US Open last year, will face Latvia's world number 48 Anastasia Sevastova in the next round.
