Rafael Nadal revealed several years ago he was told that there was "someone very good" coming up in Spain and he realized that was true after hitting the practice court with current world No. 2 Carlos Alcaraz during the 2021 Australian Open.

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.
