BELGRADE, Serbia (AP) -- The Djokovic family did not enjoy any success at their home tournament.
After defending champion Novak Djokovic pulled out of the event, his brother Marko lost in the first round to Filippo Volandri on Monday.
Marko Djokovic, a wild-card entry, was broken four times and never forced a break point of his own as Volandri beat him 6-3, 6-1.
The tournament is organized by the Djokovic family. Novak, the world's top-ranked player, pulled out because of the recent death of his grandfather, decision he called one of the hardest of his career.
In other first-round matches Monday, Dusan Lajovic of Serbia defeated fellow wild-card entry Evgeny Donskoy of Russia 7-5, 6-4, and Ivan Dodig used six breaks to overcome Adrian Ungur of Romania 6-2, 6-7 (4), 6-4.
