did he hit it with the tip of his racket?
Yeah, he did. His technique was all messed up on that serve
He was trying to guide it in, instead of actually hitting the serve. He hit it right off the tip of the racquet and it literally floated to right around the back of the court.
Nando's serve has really, really declined. You can tell he has no confidence in hitting it. Because he's scared about double faulting.
