Kokkinakis Upsets Tsitsipas at US Open

Australia has made an impressive start at the US Open with Thanasi Kokkinakis, Jordan Thompson, and Tristan Schoolkate all securing first-round victories. Kokkinakis's win was particularly notable, as he upset 11th-seed Stefanos Tsitsipas in four sets, marking his second victory at the Open in nine years. Tsitsipas revealed he is struggling with burnout and a lack of hunger, contributing to his disappointing performances this year. Schoolkate also made headlines with a comeback victory in his grand slam debut, while Thompson breezed past his opponent in straight sets. In the women's competition, Naomi Osaka returned from maternity leave to defeat Jelena Ostapenko decisively.
