Reigning champion Mikhail Youzhny was an easy quarterfinal winner Friday at the Zagreb Indoors tennis event.
The third-seeded Russian drilled 2011 Zagreb titlist Ivan Dodig of Croatia, 6-3, 6-2, at Dom Sportova.
Youzhny beat Slovak Lukas Lacko in last year's finale here.
Also in the round of eight, fourth-seeded veteran Austrian left-hander Jurgen Melzer topped big-serving Czech Lukas Rosol 6-4, 6-4 and Dutchman Robin Haase snuck past German qualifier Philipp Petzschner 6-4, 3-6, 6-0. Melzer and Haase will square off in Saturday's semifinals.
