History
2013: ATP debut in doubles
Ritschard made his ATP main draw debut at the 2013 Crédit Agricole Suisse Open Gstaad in the doubles draw partnering Alexander Sadecky.
2022: ATP and Major debuts in singles, Maiden ATP win
At the age of 28 he made his Grand Slam and ATP debut in singles after qualifying for the 2022 Wimbledon Championships. He drew fourth seeded Stefanos Tsitsipas whom 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 2022 Swiss Open Gstaad he won his maiden ATP tour match defeating eight seed Joao Sousa as a wildcard.
He made his debut at the 2022 US Open as a qualifier.
He won his Maiden Challenger title in 2022 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
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 U.S. Men's Clay Court Championships.
