VIENNA -- Austrians Jurgen Melzer and Andreas Haider-Maurer were among the quarterfinal winners Friday at Bank Austria Tennis Trophy tournament.
Melzer, the top seed and defending champ, didn't even have to lift a racquet, as seventh-seeded German Philipp Kohlschreiber withdrew because of a groin injury.
Haider-Maurer, a lucky loser from qualifying who entered the week with just two career Tour-level wins and a ranking of 157, toppled second-seeded Marin Cilic of Croatia, 7-6 (7-1), 6-4. Haider-Maurer only gained entry to the main draw when Latvia's Ernests Gulbis withdrew.
Third-seeded Spaniard Nicolas Almagro also advanced with a 7-5, 3-6, 6-3 win over eighth-seeded Juan Ignacio Chela of Argentina, while Germany's Michael Berrer rallied to post a 5-7, 6-1, 6-4 victory over fourth-seeded Marcos Baghdatis of Cyprus.
Melzer will face Almagro in one of Saturday's semifinals, while Haider-Maurer will take on Berrer in the other.
