Rafael Nadal will have one final battle with Novak Djokovic when they meet in the Six Kings Slam exhibition event on Saturday. The Spaniard is retiring after next month's Davis Cup finals in Malaga, bringing the curtain down on an incredible career.

Novak Djokovic and Rafael Nadal, who own 46 Grand Slam singles titles between them, will be among the tennis stars competing for the largest purse in tennis history.

Nadal is playing his penultimate tournament before retirement, falling to his young compatriot and setting the third-place clash with his greatest rival, Novak Djokovic. Alcaraz faced no break points and kept the pressure on the other side.

All six participants — Nadal, Djokovic, Carlos Alcaraz, Jannik Sinner, Daniil Medvedev and Holger Rune — will be paid a guaranteed $1.5 million each for their appearance in the exhibition tournament. Whoever ends up on the champion’s throne will see his earnings further increase, with the winner set to receive a whopping $6 million.
