Roger Federer moved into the Miami Open quarter-finals with a straight-sets victory over Daniil Medvedev.
Three-time champion Federer beat 13th seed Medvedev 6-4 6-2 in a rain-delayed clash carried over from the previous day.
The 37-year-old struck with the first break of the opening set at 4-4 before recovering from 40-0 down to win the next game.
Federer then broke his Russian opponent again in the opening game of the second set, and for a third time at 4-2 up, en route to completing victory in just over an hour.
The fourth seed will face South African Kevin Anderson in the last eight.
