MUNICH -- Former champion Philipp Kohlschreiber upset second-seeded Karen Khachanov 7-6 (6), 6-4 Thursday to reach the quarterfinals of the Munich Open.

Kohlschreiber, who won the tournament in 2007, 2012 and 2016, had to save a set point in the tiebreaker then earned the decisive break for a 5-4 lead in the second before serving out the match. The loss extended a recent slump for Khachanov, who has not won a single set since the Indian Wells tournament in March. He also lost his opening matches at Miami, Monte Carlo and Barcelona since then.
