Top seed Dominic Thiem fought back from a set down to reach the final of the China Open on Saturday -- and also book his place at the season-ending ATP Finals.
The Austrian will play Alexander Zverev or Stefanos Tsitsipas in Sunday's decider in Beijing after beating Karen Khachanov 2-6, 7-6 (7/5), 7-5 in two hours and 41 minutes.
The 26-year-old Thiem, ranked fifth in the world, beat former number one Andy Murray on Friday and is one victory away from a 15th career title.
But he already has reason to celebrate because the triumph over Russia's Khachanov sealed his spot in the prestigious Finals in London next month.
"For me personally, it was one big goal when I started into the season, I'm very, very happy that I made it again," said Thiem.
"But it's not because of today's win, it's because of all the season."
