World number one Novak Djokovic reached the Italian Open quarter-finals for the 15th time in a row with a straight-set win over Alejandro Davidovich Fokina.
The defending champion dropped his opening serve but recovered immediately to beat the Spanish qualifier 6-2 6-1.
He was bad-tempered in his previous match but here he was serene as he savoured the return of fans in Rome.
Second seed Rafael Nadal is in action later on Thursday when he takes on Canada's Denis Shapovalov.
Meanwhile, Britain's Andy Murray is back in doubles action alongside Liam Broady when they face Germany's Kevin Krawietz and Romania's Horia Tecau - the eighth seeds - in the second round.
