season by winning their first event, the 2014 Stu Sells Oakville Tankard. She then went off to skip the Swiss team (throwing third rocks) at the 2014 European Mixed Curling Championship. She would lead her rink of Martin Rios, Romano Meier and Jenny Perret to a bronze medal. While Tirinzoni did not return to international competition for a while (due to strong competition in her home country from teams like Alina Pätz and Binia Feltscher), she and her rink have been strong on the World Curling Tour since then. The 2015–16 season included three tournament wins, including the first slam of the year, the 2015 GSOC Tour Challenge, where she beat the World #1 Rachel Homan rink in the final. The team would also win the International Bernese Ladies Cup and the Glynhill Ladies International later that year, while she led her team to four other tournament finals. Tirinzoni continued her WCT success the following season, winning their first event, the 2016 Stu Sells Oakville Tankard, but did not win any further tournaments. She began the 2017–18 season by defending her Oakville Tankard title, which would be the third time she would win that tournament. In one of the strongest countries, with three different World Champions, including a two-time World Champion and two-time Olympic silver medalist, Tirinzoni won the right to be the Switzerland representative at the 2018 Winter Olympics. Her team finished undefeated throughout the 2017 Swiss Olympic Curling Trials. At the games, the team just missed out on a playoff spot, finishing with a 4–5 record. Heading into the 2018–19 curling season, Tirinzoni joined forces with Alina Pätz, who threw fourth rocks with Tirinzoni skipping at the third position, with Esther Neuenschwander at second and Melanie Barbezat throwing lead rocks. The team reached the final in the first Grand Slam of the season, the Elite 10. They represented Switzerland at the 2018 European Curling Championships claiming the silver medal, going on an unbeaten 9–0 run to finish top of the Round Robin, before defeating Germany 6–4 in the semi-final, and falling 5–4 to Sweden's Anna Hasselborg in the final. Having won the 2019 Swiss National Championships, the team represented Switzerland at the 2019 World Women's Curling Championship in Silkeborg, Denmark. The team got off to a shaky start posting a 2–3 record in their first five games before winning six in a row to secure their playoff spot,
