World number 19 Ekaterina Alexandrova collapsed on court and had to retire from her first-round match at the Memphis Classic due to high temperatures. Russian Alexandrova, who was the number one seed, was trailing 7-6 (7-2) 4-6 5-4 against 16-year-old compatriot Kristina Liutova in a match where temperatures reached 34C. The match was initially paused as Alexandrova tried to continue, before she received a time violation as she took too long to serve amid her struggles. It gave Liutova victory in her debut match on the WTA tour, but the teenager was left in tears on court amid the chaotic situation. The 46-year-old, whose last singles win came at this event last year, was beaten 6-3 6-3 by Austria's Anastasia Potapova.
