Career
In 2016, Witschonke was named to the Swiss team for the 2016 Winter Youth Olympics in Lillehammer. [3] Through the round robin, she led her team of third Henwy Lochmann, second Laura Engler and lead Philipp Hösli to a 6–1 record, finishing second in their pool. They then beat Sweden's Johan Nygren 7–3 in the quarterfinals before dropping the semifinal 7–5 to Canada's Mary Fay. [4] They won the bronze medal with an 11–3 defeat over Russia's Nadezhda Karelina. In the mixed doubles discipline, Witschonke competed with Estonia's Jarl Guštšin. After winning their first two games, the team lost in the quarterfinals to China's Han Yu and Great Britain's Ross Whyte. [5]
Witschonke represented Switzerland at five consecutive World Junior Curling Championships from 2016 to 2020. [6] In her first appearance, as alternate for the Elena Stern rink, the team missed the playoffs with a 4–5 record. Witschonke played in no games. The next season, she skipped her team to victory at the Swiss junior championship to qualify for the 2017 World Junior Curling Championships. There, her team lost 7–5 in a tiebreaker to South Korea's Kim Min-ji, finishing fifth. In 2018, they also narrowly missed the playoffs, again going 4–5 through the round robin and finishing seventh.
The 2019 World Junior Curling Championships was a breakthrough event for the Swiss team. They added Raphaela Keiser to their team at third who took over skipping duties, shifting Witschonke to fourth. Through the round robin, the team finished third overall with a 6–3 record, qualifying for the playoffs for the first time. After losing 8–2 in the semifinal against Canada's Selena Sturmay, the team rebounded in the bronze medal game by stealing two in the tenth end to upend China's Jiang Jiayi 6–4 and secure Switzerland's first women's world junior medal since 2015. [7] In her last year of eligibility, Witschonke led the Swiss team to another 4–5 record, placing fifth.
While also competing in juniors, Witschonke and her team of Elena Mathis, Marina Lörtscher and Anna Gut also competed on tour during the 2019–20 season. As a junior team, the team was able to find success at the Paf Masters, advancing to the semifinals and the Schweizer Cup where they finished fourth. [8] The following season, aged out of juniors, Raphaela Keiser rejoined the team at second but once again took over as skip. This shifted Witschonke to fourth, with Mathis playing third, Lörtscher at lead and Gut to alternate. Due to the COVID-19 pandemic, there were a limited number of events during the season, however, the team was able to find success in the two tour events they did play in. After another fourth-place finish in the Schweizer Cup, Team Keiser competed in the 2020 Women's Masters Basel. After a 2–1 round robin record, the team won 6–5 over Corrie Hürlimann in the quarterfinals and then upset Elena Stern 9–4 in the semifinals. They couldn't keep their momentum going into the final, however, losing 8–2 to Sweden's Anna Hasselborg. [9] At the 2021 Swiss Women's Curling Championship, they finished 3–6 through the round robin. They were, however, able to defeat Irene Schori 5–2 to win the bronze medal. [10]
Team Keiser began the 2021–22 season at the 2021 Euro Super Series where they went 2–3, missing the playoffs. They then finished fourth at the Saint Petersburg Classic, losing 7–4 to Scotland's Eve Muirhead. At the 2021 Women's Masters Basel, the team went 4–0 through the round robin before dropping the quarterfinal 8–7 to eventual champions Denmark's Madeleine Dupont. [11] Team Keiser had three semifinal finishes in a row at the Alberta Curling Series Thistle, Camrose, and the St. Galler Elite Challenge. In January 2022, they won their first tour event when they defeated Germany's Daniela Jentsch 5–2 in the final of the International Bernese Ladies Cup. [12] In February 2022, the team competed in the 2022 Swiss Women's Curling Championship for the opportunity to represent Switzerland at the 2022 World Women's Curling Championship. Through the first round, the team finished on top of the standings with a 4–1 record. They then went 2–1 through the second round, advancing to the best-of-three final against the two-time defending world champions Team Silvana Tirinzoni. After dropping the first game 10–4, Team Keiser won 5–3 to force a third game. There, Team Tirinzoni won 8–4 to secure the Swiss title, and later went on to win their third world championship title. [13]
The following season, the Keiser rink began with a semifinal finish at the 2022 Euro Super Series. [14] On tour, they reached the final of the 2022 Alberta Curling Series Major and the quarterfinals of the 2022 Saville Shoot-Out. [15] The team won their second tour event by going undefeated to claim the 2022 Women's Masters Basel in September 2022. [16] Due to their strong results early in the season, Team Keiser qualified for the 2022 National Grand Slam of Curling event. Playing without third Elena Mathis who was out due to illness, Witschonke, Keiser, and Lörtscher finished 3–1 through the round robin to qualify directly for the playoffs. This included upset victories over Kaitlyn Lawes, Gim Eun-ji, and Tabitha Peterson. [17] In the quarterfinals, they fell 6–2 to Kerri Einarson. [18] The team also competed in the next three Slams of the season, the 2022 Tour Challenge, 2022 Masters and the 2023 Canadian Open. At the Tour Challenge, the team started with two straight losses, but then beat Chelsea Carey and Tabitha Peterson to get into a tiebreaker which they lost 4–2 to Gim Eun-ji. After a winless showing at the Masters, the team just missed the playoffs at the Canadian Open, going 2–3. They were, however, able to defeat Swiss rivals Team Tirinzoni 4–3 in a C event elimination game. [19] At the 2023 International Bernese Ladies Cup, the team continued their strong play with another semifinal showing. Despite their successful season, they had a disappointing showing at the Swiss Championship. After a 4–4 round robin record, they lost 9–4 in the semifinal to Corrie Hürlimann. [20] Following the season, the team announced they would be parting ways. [21]
On April 5, 2023, Team Michèle Jäggi announced that Witschonke would be joining them as their new third with Irene Schori retiring. [22] A month later, however, Team Tirinzoni announced that Briar Schwaller-Hürlimann was removed from the team for "team harmony" reasons. Days later, it was announced that Witschonke was replacing Schwaller-Hürlimann as the team's second. [23]
