Defending champion Aryna Sabalenka battled through serving woes Wednesday to make the Australian Open third round, admitting she was relieved to get a tricky match done in straight sets. 

The World No. 1 dropped serve three times and faced 11 break points before overcoming Spain’s Jessica Bouzas Maneiro on Rod Laver Arena 6-3, 7-5, rattling off the last five games in a row.
