BELGRADE, Serbia(AP) Tournament host and top seed Novak Djokovic extended his dominance of the inaugural Serbia Open by beating fellow countryman Viktor Troicki 6-3, 6-2 to reach the semifinals on Friday.
Djokovic's family brought the ATP event to Serbia this year after buying the license from the former ABM Amro Open in the Netherlands.
The world No. 3, who had lost to Troicki in their only previous clash two years ago in Umag, broke him four times in four chances in their quarterfinal.
On Saturday, Djokovic will play fourth-seeded Andreas Seppi of Italy, who reached his first semis of the season by beating Marcos Daniel of Brazil 6-4, 7-5.
The other semifinal pits second-seeded Ivo Karlovic against unheralded Lukasz Kubot of Poland.
Karlovic hit 13 aces past Italian qualifier Flavio Cipolla to win 6-3, 6-3.
Kubot, a 179th-ranked lucky loser in the main draw, defeated Kristof Vliegen of Belgium 7-6 (6), 6-3 in his first ATP quarterfinals to become the first Pole to make the last four on tour since October 1985, when Wojtek Fibak did it at Basel. Fibak was also the last Pole to reach a final, in 1982.
