Zack Greinke has enjoyed playing in empty stadiums during the COVID-19 pandemic.

"I don't really notice fans when the game's going on, but warming up and practice before games, I mean, for me it's nice not having fans in the stands," Greinke said. "Most people like it. When the game comes on, it's the same for me."

When asked to explain further, the pitcher said: "Because then there's no one there to talk to you and ask for autographs and want pictures and all that stuff. I don't like to do that stuff. It's nice not having them, for me. Most people like it. I don't like it."

Greinke discussed during spring training in 2013 that he had social anxiety disorder since before high school but no longer considered it a problem. He did not mention anxiety while discussing the empty stadiums.
