HALLE: Defending champion Tommy Haas reached the quarterfinals of the Halle grasscourt tournament on Thursday beating Ernests Gulbis, 7-6 (7/5), 6-4, after the Latvian had saved 16 of 16 break points. World number 11 Haas will face France's Gael Monfils for a place in the semifinals. "I knew that I had to play my best tennis to stay in the tournament," said Haas, of the challenge posed by world number 38, Gulbis. "Gulbis is a great player who is on the up." Haas is one of four German players to make the last-eight after Philipp Kohlschreiber, Florian Mayer and Mischa Zverev. He is making his 13th appearance at the pre-Wimbledon warm-up and took the title for the first time in 2012, beating Roger Federer in the final. French world number nine Richard Gasquet eased past Austria's Jurgen Melzer, 6-3, 6-1, and will face Mayer on Friday. The German got the best of his Argentine namesake Leonardo Mayer, 6-2, 6-3. Kohlschreiber, the 2011 champion, beat compatriot Tobias Kamke, 6-4, 6-3 and will take on Russia's Mikhail Youzhny. Kohlschreiber has beaten his doubles partner Youzhny seven times in eight meetings, but they have never met on grass. Federer will face Russian-born Zverev, the world 156. Five-time Halle champion Federer has yet to win a title in 2013. |
