ZAGREB, Croatia, Feb. 4 (UPI) --
Top-seeded Ivan Ljubicic
Friday was a 6-3, 6-2 winner over Mikhail Youzhny
in the quarterfinals of the PBZ Zagreb Indoors tennis tournament in Croatia.
Ljubicic, who is ranked fourth in the world, plays little-known Novak Djokovic in Saturday's semifinals. The 18-year-old Djokovic wasted Ilia Bozoljac, 6-2, 6-3. The pair made history on Friday by competing in the first-ever all-Serbian quarterfinal on the ATP Tour.
Former top 10 member Tim Henman beat Andreas Seppi, 6-3, 6-4; and qualifier Stefan Koubek beat crowd favorite Ivo Karlovic, who is from Croatia, 7-6 (7-4), 6-7 (6-8), 6-3.
In the other semifinal, Henman meets Koubek.
