'Physical issue'
Zverev said he wasn't feeling 100 per cent in his match with Ruud, which limited his ability to match the Norwegian.
“I don't want to take anything away from him, to be honest, but yeah, I had my struggles,” he said. “It's a tough one, because I think he played extremely well. I had one physical issue, which against him you have to run a lot, you have to fight. Like the previous match, actually. Very, very similar.
“I wasn't really able to do that. I wasn't really able to push off my serve much, as well. You know, just everything went his way a little bit.
“At the end of the day, that's how it goes. If I break him maybe in the second set, then the match maybe can turn around. I don't use those kind of chances, and then at some point it's gonna get tough.”
And Zverev said Ruud fully deserved to be on court on Sunday.
“I would have loved to play a final here, for sure,” he said. “I saw it as a big opportunity to play a final here. But he was much, much better than me today. That's the result that there is.”
