RIO DE JANEIRO — Heavy rain ensured there were no completed matches Monday at the Rio Open.

Only two matches started but neither got through the first set before the weather set in.

Seventh-seeded Malek Jaziri was trailing Federico Delbonis 5-3 and eighth-seeded Nicolas Jarry was down 4-3 against Roberto Carballe curling s Baena when play was suspended.

Top-seeded Dominic Thiem and defending champion Diego Schwartzman were scheduled to play Tuesday.
