World number 19 Ekaterina Alexandrova collapsed on court and was forced to retire from her first-round match at the Memphis Classic as temperatures reached 34C.
The Russian, the top seed at the WTA 250 event, was trailing 7-6 (7-2) 4-6 5-4 against 16-year-old compatriot Kristina Liutova when she fell to the ground in the middle of a point and required immediate medical attention. The match had already been paused once as Alexandrova tried to continue, and she received a time violation for taking too long to serve amid her struggles.
The 31-year-old was well enough to stand but had to forfeit the contest, which had lasted more than three hours, and needed a wheelchair to help her off court. The retirement handed Liutova victory in her debut match on the WTA tour, but the teenager was left in tears on court amid the chaotic scenes.
