Ljubicic falls; Dodig wins Zagreb opener

Croatian tennis hero Ivan Ljubicic went round upset, while reigning champion Ivan Dodig of the host round winner Wednesday at the Zagreb Indoors tennis event.

The top-seeded Ljubicic was sent packing by last year's Zagreb runner-up Michael Berrer, as the left-handed German posted a 6-4, 6-4 victory, despite an 11-ace effort from the big Croat.

The former top-five star Ljubicic was the Zagreb champion back in 2006.

Berrer will meet Austrian qualifier Jurgen Melzer in Friday's quarterfinals.

Meanwhile, the fourth-seeded Dodig downed Turkey's Marsel Ilhan 7-6 (7-5), 7-5 on the indoor hardcourts at Dom Sportova.

Dodig defeated Berrer in last year's finale here.

In some other second-round action, seventh-seeded Dutchman Robin Haase outlasted German Matthias Bachinger 7-6 (7-4), 3-6, 6-3, while Melzer upended fifth-seeded Italian Andreas Seppi in a mild upset, 6-2, 6-3.

Additional first-round winners were Slovenian Grega Zemlja, Israeli Dudi Sela and Spaniard Guillermo Garcia-Lopez.

In some second-round action here on Thursday, Dodig will face Garcia-Lopez and sixth-seeded former Australian Open runner-up Marcos Baghdatis will encounter Poland's Lukasz Kubot. The Cypriot Baghdatis was the Zagreb champ in 2007.

This week's titlist will collect $90,000.

Zagreb and Montpellier, France are the first European stops on the 2012 ATP World Tour calendar.
