Carlos Alcaraz has confirmed his schedule for the rest of the season opting to play four more events this year with the ATP Finals as the last one.
Alcaraz will also likely play for Spain in the Davis Cup Finals as well which would be the final event for him but he won't get awarded points for those events so they don't really count as part of the schedule. His next event will be in Astana next week where he'll be part of a brutally strong field as the event was upgraded to an ATP 500 event:
“I’m leaving on Friday for Astana, where I will play the tournament next week. Then I will play in Basel, Paris, Turin for the Masters and finally the Davis Cup at the end of the year."
As noted above he'll travel to Basel next where he'll take part in the event where his idol dominated for many years and probably will be in attendance. Perhaps a ceremony as well, it was certainly promised by the tournament director.
After that, it's Paris, the ATP Finals in Turin and then the Davis Cup Finals back home in Spain. It will be hosted by the city of Malaga.
