Novak Djokovic strolled into the Italian Open quarter-finals on Sunday 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.
The injury-hit 37-year-old, now ranked 361 in the world, beat Djokovic in finals to win two of his three Grand Slam titles, but has now lost 20 of their 26 career meetings.
