Jannik Sinner won his 50th match of the year on Thursday to reach the US Open third round as 2022 champion Iga Swiatek stormed through.

World No. 1 Sinner defeated America’s 49th-ranked Alex Michelsen 6-4, 6-0, 6-2 to make the last 32 in New York for a fourth successive year. The 23-year-old Italian had already defeated his Californian rival just two weeks ago in Cincinnati and he repeated that outcome for his 30th hard court victory of 2024.
