Roger Federer eased into the last 16 of the Sony Open Tennis in Miami after a routine 6-3 6-3 victory over Thiemo de Bakker.
The two-time winner never looked troubled against his Dutch opponent as he continued his promising start to the 2014 season.
Federer dropped just seven points on his serve over the course of the entire match and did not face a single break point.
De Bakker, in contrast, faced a total of nine break points and dropped his serve on three separate occasions, including the final game of the match.
"I'm feeling really good with my game," said Federer, who next faces French No 9 seed Richard Gasquet.
"My confidence is high and I'm moving well. I'm excited about how I've been playing."
Gasquet set up the showdown with Federer after seeing off dangerous South African Kevin Anderson 6-3 6-4.
Novak Djokovic was originally scheduled to be out on court on Sunday but was given a walkover in the third round after his opponent Florian Mayer withdrew from the event.
The Serbian will play Tommy Robredo next after the 16th seed clinched a 6-3 6-4 victory over Julien Benneteau.
Kei Nishikori saw off Grigor Dimitrov 7-6 (7/1) 7-5 - with the latter have to help a ball girl off the court after noticing that she was feeling faint in the Florida heat.
Fourth seed David Ferrer ensured there would be no repeat of Saturday's 2.30am finish involving Sam Stosur as he beat Andreas Seppi 6-3 6-2 in just an hour and 10 minutes in the evening's final match.
