VIENNA (AP) The 213th-ranked Jaroslav Pospisil of Czech Republic stunned sixth-seeded Gael Monfils of France 7-6 (0), 7-5 to win his first match on ATP level at the Erste Bank Open on Wednesday, while seeded Czech players Radek Stepanek and Lukas Rosol advanced to the quarterfinals.
The 32-year-old Pospisil, who usually competes on the lower-ranked Challenger circuit, lost in the final qualifying round Monday but replaced Marinko Matosevic after the Australian withdrew with a shoulder injury.
"This is an amazing feeling," said Pospisil, who had lost his previous six main-draw matches.
"For sure Monfils wasn't at his best today," said Pospisil, who will play Dominic Thiem of Austria in the second round. "He arrived late from his Asia trip and I have been training here since Friday. That was a huge advantage for me."
In the opening set, Monfils held off four break chances while serving at 5-4 down but failed to score a point in the tiebreaker.
