The season finale, where the top eight singles players and doubles teams in the world face off, begins on Oct. 29.
For sure, it was the last thing I expected at the beginning of the tournament," Swiatek said.
French Open champion Swiatek also became the first player since American Serena Williams to claim five or more titles in successive years.
Swiatek also became the player with the most WTA 1000 titles before turning 23 with six, eclipsing Caroline Wozniacki's five.
"It was an amazing week," said Samsonova, whose run to a second WTA 1000 final of the season ensured she will return to the top 20.
