Rafael Nadal, in his first match since announcing he would be retiring after the Davis Cup next month, lost 6-3, 6-3 to Carlos Alcaraz at the Six Kings Slam on Thursday.

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.

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.
