Australian Open day nine wrap: Stefanos Tsitsipas tees up Karen Khachanov showdown

Stefanos Tsitsipas continued to look the most likely challenger to Novak Djokovic as he eased into the semi-finals of the Australian Open.
The third seed defeated young Czech Jiri Lehecka in straight sets and will next meet Russia’s Karen Khachanov, who benefited from Sebastian Korda’s mid-match retirement due to a wrist injury.
Wimbledon champion Elena Rybakina won a power battle against Jelena Ostapenko to set up a last-four clash with Victoria Azarenka, who saw off third seed Jessica Pegula, who continues her campaign in the doubles.
