Sinner: ‘I was not feeling really well’
I was not feeling really well,’ said the 23-year-old. ‘I think we saw that today I was struggling physically. I knew that it was going to be very, very difficult today, playing against a tough opponent but also playing against myself a little bit.
I at least felt slightly better when I went back on court. I felt like the face looked a little bit better, the colour was a little bit back. The doctor gave me some medication.
I talked with the doctor before already, before going on the court. I had a little checkup.
Yeah, it was a bit helpful. I at least felt slightly better when I went back on court. I felt like the face looked a little bit better, the color was a little bit back.
So, yeah, that helped, for sure. You know, it’s a toughconditions. You know, yesterday was hot. Today was hot again.
You know, every player, you know, struggles a little bit. When you’re not there health-wise where you want to be, it’s also even more difficult, but it helped, yeah. It gave he some small medication, and then it wasn’t slightly better.
