Carlos Alcaraz likely just played his tennis idol Rafael Nadal for the last time in their professional careers during Thursday's semifinal match of the Six Kings Slam. Although the score makes it look like Alcaraz ran away with the match at 6-3, 6-3, the 21-year-old admitted he still had to play his best in order to beat the 22-time major champion.

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.

Competing for the first time since the Olympic Games, Rafael Nadal faced world no. 2 Carlos Alcaraz in the semi-final of the Six Kings Slam in Riyadh. As was expected, the younger Spaniard scored a 6-3, 6-3 victory in under 80 minutes, arranging the title clash versus world no.
