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.

It is not yet time to say goodbye to tennis for good, for Rafael Nadal. The Spanish champion still has one event, before the final farewell that will arrive at the Davis Cup Finals in Malaga, and the event in question is The Six Kings Slams exhibition in Riyadh, Saudi Arabia.
