World number one Rafael Nadal raced past Slovenia's Aljaz Bedene to reach the third round of the Monte Carlo Masters in Monaco.
Defending champion Nadal beat Bedene, ranked 58th in the world, 6-1 6-3 in 77 minutes.
Ex-world number one Novak Djokovic beat Croatia's Borna Coric but needed 10 match points before closing out a 7-6 (7-2) 7-5 win over the world number 39.
"After two years finally I can play without pain," said Djokovic.
"Under the circumstances and considering I haven't played too many official matches, I thought I played well."
Spaniard Nadal is continuing his return from a hip problem that forced him to retire from his Australian Open match against Marin Cilic in January.
