ZAGREB, Croatia, Feb. 3 (UPI) -- Second-seeded Ivan Ljubicic won 60 percent of the points Thursday in advancing to the quarterfinals of the Zagreb Indoors tennis tournament in Croatia.
Ljubicic, playing in his home country, took more than three-quarters of the points on serve and nearly half when receiving in a 6-2, 6-3 victory over Daniel Brands. He was good on only 51 percent of his first serves but still didn't face a break point.
Qualifier Alex Bogomolov Jr. was even more efficient in defeating No. 7-seeded Philipp Petzschner 6-1, 6-2. The match took just 53 minutes as Bogomolov dropped only 12 points in eight games on serve. Bogomolov's first-round match took nearly three hours.
Ivan Dodig had four service breaks in a 6-2, 6-3 win over Illya Marchenko and fourth-seeded Richard Gasquet advanced in a walkover when Arnaud Clement was unable to play Thursday because of a shoulder injury.
A quarterfinal match pitting top-seeded Marin Cilic and No. 5 Florian Mayer was determined Wednesday. Thursday's results set up the rest of the quarters with Gasquet playing eighth-seeded Michael Berrer, Bogomolov meeting No. 3-seeded Guillermo Garcia-Lopez and Dodig paired against Ljubicic.
