Dominic Thiem denies Roger Federer in Stuttgart grass upset

Baden-Württemberg: Dominic Thiem came through a pair of rain delay distractions to stun top seed Roger Federer 3-6, 7-6 (9/7), 6-4 on Saturday for a place in the Stuttgart gass final.

The French Open semi-finalist who moved into the ATP top 10 only this week, produced the biggest win of his promising career after defeating the Swiss great on clay last month in Rome.

Third seed Thiem will play for his fourth title of the season on Sunday against either Juan Martin del Potro or Philipp Kohlschreiber.
