Speaking after the match, Alcaraz was quick to reassure everyone that the issue was nothing serious.
“I'm feeling good. Just as a precaution, I called the physiotherapist when he broke my serve on the last point. I felt something that wasn't working well in my knee. After 5, 6 points, it disappeared,” Alcaraz explained. “I asked the physiotherapist just to take care of the knee, because there was 1 set left, I had to be ready and feeling good physically. Precaution. I'll talk to my team, but I'm not worried about it.”
