Rafael Nadal is headed to the Middle East this fall.

The 37-year-old Spanish professional tennis player, the former World No. 1, is set to play in an exhibition event in Saudi Arabia in October, the kingdom’s latest move into tennis.

Nadal will be joined by Novak Djokovic, Carlos Alcaraz, new Australian Open champion Jannik Sinner, Daniil Medvedev and Holger Rune in what’s being touted as the “6 Kings Slam” in Riyadh.

All but Rune have won at least one Grand Slam title. Djokovic holds the men’s record with 24, followed by Nadal with 22. Alcaraz has two, and Sinner and Medvedev one apiece.

Nadal was recently announced as an ambassador for the Saudi Tennis Federation.

The ATP men’s tour moved its annual tournament for leading players who are 21 and under to Jedda, and the WTA women’s tour is in negotiations to put its season-ending championship in Saudi Arabia.

Saudi Arabia has pumped huge amounts of money into sports, such as soccer, Formula One, boxing and golf, with critics accusing the country of using its Public Investment Fund to engage in sportswashing over its human rights record, including the treatment of women and members of the LGBTQIA+ community.

The kingdom denies accusations of human rights abuses and says it protects its national security through its laws.
