Marta Kostyuk kickstarted her 2025 season with a 6-2, 7-5 win over Coco Gauff at the Qatar TotalEnergies Open, shocking the No. 3 seed in 73 minutes on Tuesday.
The world No. 21 had won back-to-back matches just once so far this year but pulled off her ninth Top 10 victory—and third over a Top 5 player—to hand Gauff, who last played in Australia where she lost in the quarterfinals, a second straight defeat.
Gauff had begun the year on fire, winning her first nine matches of her season for the third time in her career, becoming only the fifth woman to do so after Margaret Court, Stefanie Graf, Monica Seles, and Serena Williams.
