Nadal and Swiatek named ITF world champions after stellar 2022 season
World number two Nadal fought back from two sets down to defeat Daniil Medvedev in January's Australian Open final to capture his 21st Grand Slam trophy, before sealing a record-extending 14th French Open title in June for his 22nd major.
The Spaniard joins his friend and recently-retired rival Roger Federer as a five-times ITF world champion behind Pete Sampras (6) and 2021 winner Novak Djokovic (7).
"I'm very happy to be named ITF World Champion for the fifth time," Nadal, who also bagged the award in 2008, 2010, 2017 and 2019, said in a statement.
"When I first won the award... I wouldn't have expected to still be playing at such a high level 14 years later. It was special to win the Australian Open for a second time, and of course to win Roland Garros.
"I'm grateful for the support of my team and my fans around the world and I'm already looking forward to the 2023 season."
Swiatek went on a 37-match winning run and won the French and U.S. Opens as well as titles at Doha, Indian Wells, Miami, Stuttgart, Rome and San Diego. She won 67 matches overall and topped the list of finals reached and trophies won.
Swiatek, who was also named WTA Player of the Year, said major awards in a "big year" showed how far she had come.
"I appreciate it and I want to thank the ITF," Swiatek, who is the first Polish singles player to win the ITF award, said.
"It wouldn't have happened without my team, my family, and my fans from Poland and all over the world. Consider it our joint award for amazing adventure on court in 2022."
In the men's doubles category, American Rajeev Ram and Briton Joe Salisbury won the award for the first time, while Czech duo Barbora Krejcikova and Katerina Siniakova took the women's doubles honour for the third time.
