Four seeds, including Guillermo Garcia-Lopez and Andreas Seppi, posted second-round wins Thursday at the Zagreb Indoors tennis event.
The third-seeded Spaniard Garcia-Lopez grounded Bosnian Damir Dzumhur 6-1, 6-1, while the fifth-seeded Italian Seppi held off Brit James Ward 7-5, 6-7 (4-7), 6-3 at Dom Sportova.
Seppi stunned Roger Federer in the third round at the Australian Open two weeks ago.
"I didn't have so much energy today," admitted Seppi on Thursday. "I felt a little bit down. I didn't feel I could play as aggressively as I wanted, and I gave him a little bit more space to play. I think he played really well. He served good at important moments. I could have actually finished in two sets as I was 7-5, 4-2 up, but I lost the tiebreak. Anyway, I am happy to be through and I will try to improve next match."
An upset came when Lithuanian Ricardas Berankis tackled fourth-seeded Gilles Muller of Luxembourg 3-6, 7-6 (7-5), 6-4, while seventh-seeded Serb Viktor Troicki avoided an upset by whipping Japanese Go Soeda 6-3, 6-1 on Day 4. The resurgent Troicki was a titlist in Sydney last month.
Troicki will meet Garcia-Lopez in Friday's quarterfinals, while Berankis will face Seppi.
Another result saw eighth-seeded Spaniard Marcel Granollers outlast Croatia's Ivan Dodig 7-6 (10-8), 4-6, 6-3. Dodig captured the title here in 2011.
The 2015 Zagreb champion will collect $90,000.
