Pitching in big-market Los Angeles is not what worries Zack Greinke.

"The thing that I was always worried about throughout is not so much this," he said Friday, "but when I go home in the offseason I don't want people following me around or everywhere I go people talking to me and stuff.

"The last season with Milwaukee and this offseason and going back to Orlando, people have talked to me a little bit more, but I guess I've gotten kind of used to dealing with people recognizing me and talking to me."

That's what social anxiety disorder is: Orlando can be more terrifying than Los Angeles.

According to the Mayo Clinic website, social anxiety disorder is a chronic mental health condition in which "everyday interactions cause irrational anxiety, fear, self-consciousness and embarrassment."

Greinke has had the condition since before he entered high school.

The pitcher hasn't addressed the topic since his first spring training with the Milwaukee Brewers in 2011. Maybe his silence the past two years have allowed those crude theories to foment, in Anaheim last summer and now in Los Angeles: The more people surrounding him, the harder it is to pitch.

Apparently that's not how it works.

"I never had a problem with people watching me," Greinke said. "That's never bothered me. That might bother people but that's never bothered me at all. I don't want them looking at me in my house."
