The ITF determines its awards based on criteria that include all events and give special weight to the four major championships and two team events, the Billie Jean King Cup and Davis Cup.?

Nadal won despite finishing No. 2 in the ATP rankings behind Carlos Alcaraz, while Swiatek topped the year-end WTA rankings.

It's the fifth time Nadal has earned the ITF honor, following 2008, 2010, 2017 and 2019. He raised his Grand Slam title total to a men's-record 22 by winning the Australian Open in January and the French Open in June.

This is Swiatek's first time as ITF World Champion and it comes after she won the French Open and the U.S. Open for her second and third career major trophies. She led the WTA with eight titles this year and put together a 37-match winning streak that was the longest unbeaten run in women's tennis since 1997.?

The ITF awards will be presented at a ceremony on July 8 at the Victoria and Albert Museum in London.
