Swiss Women's Curling Championship. This put her in a playoff against 2020 Champions Team Stern for the right to represent Switzerland at the 2021 World Women's Curling Championship, as the 2020 Worlds were cancelled due to the COVID-19 pandemic. Tirinzoni beat Stern in the playoff, and represented Switzerland at the World Championship, which was played in a bio-secure bubble in Calgary, Canada due to the pandemic. There, she led her rink to a 12–1 round robin record, including scoring a rare eight-ender against Denmark, the first time an eight-ender has ever been scored at a World Championship. In the playoffs, Tirinzoni defeated the United States in the semifinal, and then Alina Kovaleva representing RCF (Russia) in the final to win the gold medal, successfully defending her 2019 championship, becoming the first Swiss skip to win back to back titles. While also in the Calgary bubble, Team Tirinzoni played in two Grand Slam events, making the final at the 2021 Champions Cup and the semifinals at the 2021 Players' Championship. Team Tirinzoni had a slow start to the 2021–22 season, not reaching any finals in their first five tour events. At the first two Slams, the 2021 Masters and the 2021 National, they went undefeated until losses in the quarterfinals and semifinals, respectively. At the 2021 European Curling Championships, the team failed to reach the playoffs for the first time, finishing in fifth with a 6–3 record. The next event the team played in was the 2022 Winter Olympics, where they found their footing for the first time during the season. They finished in first place after the preliminary round with an 8–1 round robin record. This earned them the top seed in the playoff round. They then, however, lost the semifinal to Japan's Satsuki Fujisawa and the bronze medal game to Sweden's Anna Hasselborg, placing fourth. Immediately after the Olympics, the team entered the Swiss Women's Curling Championship where they were once again able to defend their title, earning the right to represent Switzerland at the 2022 World Women's Curling Championship. At the championship, Team Tirinzoni dominated the competition, finishing the round robin with an unblemished 12–0 record. They then beat Sweden's Hasselborg in the semifinal to qualify once again for the world championship final where they would face South Korea's Kim Eun-jung. Switzerland took a three point lead early, but Korea was able to tie the match later on.
