British number one Kyle Edmund’s start to the clay-court season continued with a 6-2 6-4 victory over Moldova’s Radu Albot in the Grand Prix Hassan II.
World number 26 and second seed Edmund, 23, won in an hour and a quarter in the last-16 match in Marrakesh.
His first-round match on Tuesday lasted only 16 minutes as Jiri Vesely retired when trailing 5-0.
Edmund reached the Australian Open semi-finals in January, but lost early on at Indian Wells and Miami.
He will play Tunisia’s Malek Jaziri in the quarter-finals. The world number 91 beat eighth seed Mischa Zverev from Germany in the last 16.
