Fish didn't seem injured but there was this weird moment at deuce when Phau was serving for the set. Phau hit this short angled backhand around the servers box cross court and Fish dove and wasn;t getting up. Everyone was silent for like 30 second and Fish's headband fell off and he got on his knees and smashed his racket and I just had this feeling he was gonna retire or something but was just a scare
Fish has a lot of weird moments like that
Good thing he's OK though.
