At the Serbia Open in Belgrade, Feliciano Lopez upset fourth-seeded fellow Spaniard Albert Montanes 6-4, 6-4 to reach the semi-finals, where he will play Filippo Volandri, after the Italian defeated Spain's Marcel Granollers, 6-2, 6-4. Lopez converted two out of nine break points to reach his first ATP semi-final of the year.

In the third quarter-final, Serbia's Janko Tipsarevic edged Somdev Devvarman, of India, 6-3, 3-6, 6-4 and will next play the winner of the match between Novak Djokovic and Blaz Kavcic of Slovenia. The second-ranked Djokovic, of Serbia, is seeking his 26th consecutive victory this year.
