Novak Djokovic strolled into the Italian Open quarter-finals on Thursday with a routine 6-2, 6-2 win over Stan Wawrinka, while Iga Swiatek continued her bid for a fifth straight tournament victory by beating Victoria Azarenka. Chasing a sixth title in Rome, Djokovic took one hour, 16 minutes to get past his Swiss opponent without stretching himself and will now face Felix Auger-Aliassime in the last eight. Wawrinka, whose first-round victory over Reilly Opelka was his first win in 15 months, was no match for top seed Djokovic and beyond a few classic passing shots he offered little resistance.
