The Swiss women are unable to take their chance at the new Challenger tournament in Montreux.
Jil Teichmann (WTA 202) was the last representative to fail in the quarter-finals on the clay court by Lake Geneva.
Despite a good start and a 5:3 lead in the third set, the former world number 21 and 2022 team world champion lost 6:1, 3:6, 5:7 to Spain's Nuria Parrizas-Diaz, who was seeded number 4 and ranked more than 100 places higher.
