Carlos Alcaraz’s ATP Finals debut ended in disappointment as he fell 6-1, 7-5 to Norway’s Casper Ruud. The Spanish star made 34 unforced errors, struggling with consistency throughout the match. Ruud, who had been in poor form recently, mounted a comeback from 5-2 down in the second set, securing his first career win over Alcaraz and putting himself in a strong position for the semifinals.
