Alexander Ritschard

Ritschard made his ATP Tour main-draw debut at the Suisse Open Gstaad in the doubles draw, partnering Alexander Sadecky.

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. In October, 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.

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. In April, he returned to the top 175 with lifting his second trophy at the 2024 Savannah Challenger.

Following a Challenger final at the 2024 Heilbronner Neckarcup in June and a title at the 2024 Salzburg Open in July, he reached a new career-high of No. 135 on 29 July 2024.

Following a semifinal showing at the 2024 Copa Sevilla, he reached the top 125 at No. 121 in the singles rankings on 23 September 2024. After winning his third Challenger at the 2024 Lisboa Belém Open, he reached the top 100 in the rankings at 30 years of age.
