UMAG, Croatia, July 29 (UPI) --
Rain caused the postponement of all four second-round matches Thursday at the Croatia Open tennis tournament.
Weather issues caused the matches to be pushed back to Friday, where two quarterfinal matches were already on the schedule.
The matches delayed included second-seeded Jurgen Melzer's draw against Jan Hajek and third-seeded Ivan Ljubicic, the local favorite for this event, versus Ivan Dodig, another Croat.
Also Andreas Seppi was to have gone against Olivier Rochus and Bjorn Phau was to have played Portito Starace.
The two quarterfinals already set have top-seeded Nikolay Davydenko facing eighth-seeded Juan Ignacio Chela and fourth-seeded Juan Carlos Ferrero battling No. 6-seeded Alexandr Dolgopolov.
Davydenko beat Ferrero in last year's Croatia Open final.
