Moutet also took on an umpire during his first-round victory over Stan Wawrinka at the US Open. he complained about having to wait too long on his serve.
“When I’m serving … you have to do something. You have to do your job,” Moutet said, as picked up by court-side microphones.
“I was waiting the whole match on my serve. You don’t have to call the ball anymore. You can call it late when the guy is late. You’re here to call the score, that’s it. One pay check for it. I wish I was doing the same job.”
