16-year-old qualifier Liutova wins WTA debut as top seed Alexandrova collapses in Memphis heat

World No. 19 and top seed Ekaterina Alexandrova retired from her Memphis Classic first-round match on July 28, collapsing mid-point in 34°C heat. The WTA attributed the retirement to heat illness. Her opponent, 16-year-old qualifier Kristina Liutova, trailed 4-2 in the decider but led 5-4, 15-30 — two points from victory — when Alexandrova stopped. Match time: 3 hours 11 minutes. Liutova was in tears.
