Anna Blinkova (Russia) won the deciding set of her second round match against third seed Elena Rybakina (Kazakhstan) 7–6 (22–20) at the Australian Open on 18 January 2024. At 42 points, it was the longest-ever tie-break in a Grand Slam singles match – male or female.
On her 10th match point, Blinkova progressed 6–4, 4–6, 7–6 (22-20) against the tournament’s 2023 finalist. Third seed Rybakina spurned six match points of her own in a third set that lasted 93 minutes on Rod Laver Arena.
