Winkelhausen was the alternate on the Swiss team (skipped by Binia Feltscher-Beeli) at the 2010 Ford World Women's Curling Championship, finishing 10th.

The team won two WCT events in their first season together (the 2014 Red Deer Curling Classic and the 2015 International Bernese Ladies Cup.)

The Swiss team claimed the silver medal after 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.

Tight victories over China in the qualification game, and South Korea in the semi-final set up a repeat of the European Championship final against Hasselborg and Sweden.

They were able to turn the tables on Sweden, with Pätz making a draw to the four-foot in the extra end for an 8–7 win which meant they were crowned the 2019 world champions.
