Jacquemot Stuns Kostyuk in Historic Australian Open Marathon

Day one of the Australian Open 2026 entered the history books as France’s Elsa Jacquemot edged past World No.20 Marta Kostyuk in an epic three-hour, 31-minute first-round clash at Melbourne Park.

Jacquemot prevailed 6-7(4), 7-6(4), 7-6(10-7), becoming the first women’s singles match at the tournament to feature tiebreaks in all three sets since final-set tiebreaks were introduced in 2019.

The 22-year-old saved a match point, overcame a tense injury delay, and sealed her first top-20 win and maiden Australian Open main-draw victory in front of a record day-session crowd.
