History
2013: ATP Tour debut in doubles
Ritschard made his ATP Tour main-draw debut at the Suisse Open Gstaad in the doubles draw, partnering Alexander Sadecky.
2022: ATP & major debuts & first singles win
At the age of 28, he made his Grand Slam and ATP Tour debut in singles, after qualifying for the 2022 Wimbledon Championships. He drew fourth seeded Stefanos Tsitsipas who, despite his ranking, performed very poorly on grass, having lost in the first round of his two previous Wimbledon appearances. Ritschard stormed out to a 4–1 lead in the first set, on serve, looking like another possible upset but Tsitsipas rallied to win the set in a tiebreaker and the match in four sets.
At the Swiss Open, he won his maiden ATP Tour match defeating eighth seed Joao Sousa as a wildcard.
He made his debut at the US Open as a qualifier.
He won his maiden Challenger title in Hamburg defeating Henri Laaksonen, after the fellow Swiss retired in the second set when Ritschard was 7–5, 6–5 up and had 40–30 on his service game, climbing 50 positions back to No. 166 in the singles rankings on 24 October 2022.
2023-2024: Second Challenger title, back to top 175
He qualified for the main draw of the 2023 BMW Open and defeated Jan-Lennard Struff but lost in the second round to Marcos Giron.
Ranked No. 194, he also qualified into the main draw of the 2024 US Clay Court Championships. He returned to the top 175 with lifting his second trophy at the 2024 Savannah Challenger.
