After suffering his 12th straight first-round loss in a Grand Slam at the Australian Open, Australian Marinko Matosevic rages at the chair umpire, fans, and his coach in his post-match press conference.

Matosevic was upset for incurring time violations from the chair umpire in his five-set loss to Kei Nishikori.

“That was bulls---,” Matosevic said. “When have you seen that? A guy's taking his bottle to the back of the court [during a game]. He can do it, I'll take a drink.

“The other thing is, I shouldn't have gotten the first time warning either for equipment. My hat like went loose. The thing broke at the back. I went to change back and [the chair umpire's] like, 'I'm going to give you a time violation.' I'm like, 'Okay.' The next one was a really important game. Just kept on going back and forth. He went to get a drink, so I went to get a drink. She calls a point penalty. Nothing I can do.”

Matosevic also asked the umpire to ask fans to stop calling him “Mad Dog.”

“Hearing the stupid nickname—it's not my nickname. Some idiot put it on Wikipedia,” Matosevic said.

The 28-year-old Melbourne resident was also upset with his coach, Mark Woodforde, for not being vocal enough.

“I wanted my coach to vocally support me, but he wouldn't,” he said. “I've spoken about it before. Not disappointed in the lack of support. Some players need verbal support, some don't. I'm a player that likes it and needs it and wants it. So if my coach is just going to sit there and clap, I expect more.”

Woodforde told BBC Radio that Matosevic's reaction was “Really amateurish of him and unprofessional. This is a bloke that I spent a good portion of 2013 trying to help get his career back on track, which I think we were able to achieve that. What dogs Marinko is he becomes very amateurish on the court and he starts to battle—he’s battling with himself and he doesn’t want to take any responsibility for what goes on on the court. It’s very easy to blame others.”
