Top seed Dominic Thiem missed a chance to pass Roger Federer and become the world`s third-ranked player when he was knocked out of the Rio Open by Italian qualifier Gianluca Mager in a rain-delayed quarter-final match on Saturday.
Mager, 25, completed the victory 7-6(4) 7-5 after leading 2-1 in the second set when play was halted on Friday.
"It’s unbelievable,” the Italian said. “For me, it was a dream only to play with him. Now that I beat him, it is a dream. He is a great, unbelievable player… I am very emotional.”
The tournament was Thiem`s first since reaching the Australian Open final last month.
Mager held his opening three service games to serve for the match at 5-4. But after dropping serve to Austrian Thiem, he landed back-to-back winners and on his first match point fired an ace out wide to complete the win.
Both semi-finals were suspended because of rain on Saturday and will be completed on Sunday.
Mager led Hungary`s Attila Balazs 7-6(4) 3-3 and Cristian Garin of Chile was in front of Croatia`s Borna Coric 6-4 4-4.
