Seven-time champion Roger Federer reached the Wimbledon quarter-finals by dismantling Steve Johnson 6-2 6-3 7-5.
Federer, 34, has lacked matches and form this summer but showed glimpses of his imperious best on Centre Court.
He will now play 2014 US Open champion Marin Cilic as he hunts a record-breaking eighth men's singles title.
Johnson, 26, shares a coach with Sam Querrey but never looked like pulling off an upset to compare with Querrey's third-round defeat of Novak Djokovic.
Federer broke world number 29 Johnson in the sixth and eighth games of the first set and maintained that momentum as the contest developed.
