Swiatek passes Kenin test at Australian Open, Ruud roars

MELBOURNE : Iga Swiatek came through a testing opener in her hunt for a first Australian Open title on Tuesday as the world number one battled past 2020 champion Sofia Kenin 7-6(2) 6-2 in sweltering heat on Rod Laver Arena.

Russian 14th seed Daria Kasatkina overcame American Peyton Stearns 6-2 3-6 6-2 but she too struggled with the weather.
