Tommy Haas outlasted qualifier Blaz Kavcic of Slovenia 6-1, 4-6, 6-4 Wednesday to advance to the third round of the German Tennis Championships.
The second-seeded Haas blew a 4-1 lead in the third set. But he held serve and broke to clinch the match when Kavcic sent a forehand long.
The 35-year-old Haas was runner-up in the tournament last year and is the oldest player in the top 100. He is looking for his second title at home this season after winning in Munich.
Defending champion Juan Monaco of Argentina, seeded fifth, beat Gael Monfils 6-4, 6-4.
