Team Schwaller (2022–Present)
Following the 2021–22 season, the top two Swiss rinks, Schwaller and de Cruz, announced that they would be disbanding. A new team was then created consisting of Lachat, Sven Michel, Yannick Schwaller and Benoît Schwarz-van Berkel for the 2022–23 season. Schwaller would skip the team but throw third rocks with Schwarz-van Berkel throwing fourth rocks, Michel playing second, and Lachat at lead. [10] The new Schwaller rink would represent Switzerland at the 2022 European Curling Championships, where they would go 8–1 in the round robin, but lose to Scotland's Bruce Mouat 5–4 in the final, winning the silver medal. Schwaller would go on to represent Switzerland at the 2023 World Men's Curling Championship, where they would win a bronze medal, beating Italy's Joël Retornaz 11–3 in the bronze medal game. Schwaller would again represent Switzerland at the 2023 European Curling Championships, once again winning a bronze medal over Italy's Retornaz, this time by a score of 8–4 in the bronze medal game. At the 2024 World Men's Curling Championship, the Swiss team would finish a disappointing 7th, going 6–6 in round robin play. However, Schwaller would have a strong season on the Grand Slam of Curling tour, finishing in the semifinals of both the 2023 National and 2023 Masters.
Schwaller would again have a strong start to the 2024–25 curling season. At the Grand Slam events, Schwaller would finish in the quarterfinals of the 2024 Tour Challenge and semifinalists at the 2024 Canadian Open. At the 2024 European Curling Championships, the team would finish 4th, losing to Norway's Magnus Ramsfjell in the bronze medal game. The Schwaller rink would return to the 2025 World Men's Curling Championship, where they would go 9–3 in the round robin, but lose in the final to Scotland's Mouat 5–4, finishing in second and winning the silver medal.
