Krefeld:Germany advanced to the quarterfinals of the Davis Cup with a 3-2 win over Croatia, with Tommy Haas earning the deciding point by beating Ivan Ljubicic 6-2, 7-6 (7), 6-4. Haas, an Australian Open semifinalist, hit an ace to close out the first reverse singles match and give Germany an insurmountable 3-1 lead. Marin Cilic later beat Benjamin Becker 4-6, 6-1, 1-6. "I'm very proud of my performance. I'm happy I could get the third point," Haas said. "We weren't the favorites. This is very good. We have been very close during the past couple of years but couldn't advance." Three time champion Germany, a three-time Davis Cup champion, reached the quarterfinals for the first time in six years and faces Belgium on April 6-8. Haas, backed by a vocal crowd of 4,600, had no trouble returning serve against one of the biggest servers in tennis as he ran his Davis Cup record to 18-6. He fought off a set point in the second set tiebreaker against Ljubicic, then won 9-7 when the Croat missed a hard backhand down the line. Alexander Waske and Michael Kohlmann set the stage for Germany's triumph on Saturday when they won the doubles, handing Ancic and Ljubicic their first Davis Cup loss in seven matches. "That was the best doubles match we ever played," Kohlmann said. Ljubicic gave Croatia its only point when he swept past Becker on Friday. The German was making his Davis Cup debut.
