VIENNA (AP) Janko Tipsarevic reached his 13th quarterfinal of the season by defeating Ernests Gulbis 6-3, 6-4 Thursday at the Erste Bank Open.
Tipsarevic will face Aljaz Bedene of Slovenia in the quarterfinals. Bedene edged Donald Young of the United States 7-6 (4), 6-7 (2), 6-3.
The ninth-ranked Tipsarevic, who is looking to qualify for the season-ending ATP World Tour Finals, dropped serve once in each set but dominated play from the baselines.
``I have to be pumped for every single point and not think what's going on behind me or ahead of me,'' he said. ``The only thing I care about now is winning my next match. I don't think about winning the tournament or about reaching London.''
Tipsarevic said his new attitude developed after Serbia won the Davis Cup, helping him become a consistent top-10 player this year.
``I don't feel I improved my forehand, backhand or serve dramatically,'' he said. ``I just feel that now I am living and breathing tennis outside of the tennis court as much as I am on the tennis court. ... This changed after winning the Davis Cup. I realized I wasn't getting any younger and that I would regret it if I realized one day that I could have reached more in my career.''
Marinko Matosevic defeated wild card Dominic Thiem 6-3, 7-6 (5) to set up a quarterfinal match against top-seeded Juan Martin del Potro. Grega Zamlja beat Matthew Ebden 7-5, 6-4, and Paolo Lorenzi defeated Vasek Posposil 6-4, 6-4.
