British number one Kyle Edmund eased to victory over Russia's Daniil Medvedev to set up a second-round tie with Novak Djokovic at the Madrid Open.
Edmund, 23, saved five break points in the first set as the match remained on serve at 4-4.
The world number 22 then reeled off eight straight games to win 6-4 6-0 in one hour 17 minutes.
He will likely enter the world top 20 should he beat 12-time Grand Slam champion Djokovic on Wednesday.
The Serbian former world number one, who has struggled since returning from elbow surgery, secured his first win against a top-20 opponent in almost a year by beating Kei Nishikori on Monday.
