Roger Federer beat British number one Kyle Edmund to reach the quarter-finals at Indian Wells.
The Swiss, a five-time champion in California, eased past Edmund 6-1 6-4 in just over an hour.
World number four Federer, who has yet to drop a set at the tournament, saved all seven break points that he faced and won 79% of first serve points.
Second seed Rafael Nadal also reached the last eight with a straightforward 6-3 6-4 victory over Filip Krajinovic.
Edmund, who won the Indian Wells second-tier Challenger event last week, struggled on serve in the opening set.
