Team USA is out of the Davis Cup as they were beaten by Italy but there is very little interest in the competition stateside anyways.
Tennis is popular in the US but it's far less popular than some other sports. It's not so different anywhere else in the world and outside of the grand slam, it rarely makes news. Fritz wanted to win it because he cares about the competition even though he knows very few back home would:
"It's obviously way more important for us. I think no one really cares I think if we win. If we were to win Davis Cup, I don't think it would be even talked about on ESPN or our sports channels in the U.S. Maybe we'll win and I'll be pleasantly surprised, but yeah, I don't think so."
Pietrangeli on Berrettini standing by his team at Davis Cup despite injury: "It's a noble gesture"
"But we all want to win. The importance of Davis Cup for me is basically like you either win the whole thing or you don't. It's not the kind of thing where we make finals and I'm, like, I'm happy we made finals. It's like lose quarterfinals, lose semifinals, lose finals, it's all the same. It's either you win or you don't."
