Dominic Thiem has qualified for the final of the ATP Finals on Saturday. The Austrian dealt with defending champion Alexander Zverev and will face Stéfanos Tsitsipás in the final, who won against Roger Federer earlier in the day.

Number five in the world Thiem did not give up a set against Zverev, the global number seven. It became 7-5 and 6-3 at the O2 Arena in London.

The 26-year-old Thiem is in the final of a major tournament for the third time in his career. Both this year and last year he was a losing finalist on Roland Garros.

Zverev, four years younger, won the ATP Finals last year by settling with Novak Djokovic in the final. At Grand Slam tournaments he did not get any further than the quarter-finals.

Earlier in the day, twenty-time Grand Slam winner Federer was unable to withstand 21-year-old Tsitsipás, who were 6-3 and 6-4. Federer, who was the number three in the world compared to the number six, was sometimes sloppy at the important moments.

The 38-year-old Federer reached the final of the ATP Finals in 2003 and was also in the final battle in 2004, 2005, 2006, 2007, 2010, 2011, 2012, 2014 and 2015. He won the prestigious end-of-year tournament in 2003, 2004, 2006, 2007, 2010 and 2011 and is therefore the record holder.

For Tsitsipás, this is the first time in his career that he has reached the final of a major tournament. At Grand Slams the semifinals at the Australian Open is the best result of the talented Greek. The final of the ATP Finals is Sunday.
