Coco Gauff Grinds Past Marta Kostyuk Into Australian Open Semis
US Open champion Coco Gauff overcame huge resistance from the unseeded Marta Kostyuk on Tuesday to move into her first Australian Open semi-final. The American fourth seed wore down the Ukrainian in hot conditions on Rod Laver Arena to clinch a scrappy encounter 7-6 (8/6), 6-7 (3/7), 6-2 in three hours and eight minutes. She will face either defending champion and second seed Aryna Sabalenka or ninth-seeded Barbora Krejcikova on Thursday for a place in the final. After showing ominous form to race into the last eight, it was a far from convincing display by the 19-year-old, who struggled on serve and fluffed countless opportunities.
