Federer was slated to meet Joao Sousa on Wednesday, eight-time Rome champion Nadal was scheduled to play Jeremy Chardy and Djokovic was up against Denis Shapovalov. Also, top-ranked Naomi Osaka was to play Dominika Cibulkova.
But consistent rain at the Foro Italico wiped out the entire day and evening sessions. Better weather is forecast for Thursday and Friday.
