MELBOURNE: Sania Mirza and Rohan Bopanna moved into the Australian Open mixed-doubles semifinals without striking a ball when their opponents Latvia's Jelena Ostapenko and David Vega Hernandez of Spain withdrew from the last-eight clash on Tuesday.
Ostapenko, who lost the women's quarterfinal against Elena Rybakina, complained about mental fatigue resulting from the scheduling in her post-match conference.
