Britain’s Johanna Konta reached the US Open third round – despite collapsing on court with blurred vision, breathing issues and an increased heart rate.
The 13th seed led Bulgaria’s Tsvetana Pironkova 6-2 5-6 at Flushing Meadows when she crouched down to her knees and began hyperventilating.
Medical help arrived after several minutes and Konta, 25, took a lengthy break before winning 6-2 5-7 6-2.
“My heart rate spiked and I couldn’t really control my breathing,” she said.
“It was basically very embarrassing. I started hyperventilating. I started shaking. That’s why I went down on the ground, because I was quite violently shaking.”
Konta followed compatriot Kyle Edmund on to court 13 after the Yorkshireman had reached round three by beating American wildcard Ernesto Escobedo.
Meanwhile, Andy Murray beat Spain’s Marcel Granollers to reach the third round as rain hammered down on the new roof above Arthur Ashe Stadium.
The Briton, seeded second, won 6-4 6-1 6-4 as a storm passed over New York, suspending play on the outside courts.
Murray goes on to face Frenchman Gilles Simon or Paolo Lorenzi of Italy in the last 32 on Saturday. (BBC Sport)
