"I was like, 'Why is my TV shaking?'" said Swisher, who quickly realized he was experiencing an earthquake. "That was my first one. I couldn't believe it. In New York?"
Yes, in New York, Boston, Philadelphia, Washington, D.C., and several other cities that aren't used to having noticeable seismic activity.
The 5.9-magnitude earthquake was centered near Richmond, Va., and struck at 1:51 p.m. ET. Slight tremors were felt by early-arriving staff at Yankee Stadium, as bobbleheads quivered in the offices.
Electricians and engineers went through a thorough checklist before Tuesday's game against the A's and found no irregularities in the stadium, the team said.
Yankees designated hitter Jorge Posada said that he was at home and felt the quake, which wasn't his first but seemed to be his strongest.
"Everything was shaking, but it was short," Posada said. "In Puerto Rico, my mom would always say, 'Did you feel the earth moving?' and stuff, but growing up, they weren't as big as today."
Yankees manager Joe Girardi was working out in the stadium gym and said he didn't notice anything out of the ordinary, though his phone lit up with text messages soon after.
"A couple of our people talked about it, where they just felt it a little bit," Girardi said. "I've never felt one, and I don't want to. [Head athletic trainer Gene Monahan] said he felt it, and I was giving him a hard time about it."
Phil Hughes was driving to the Stadium and didn't notice anything, but for the southern California product, it wasn't the first time he missed one.
"As a kid, my parents would always wake me up when we had one, but I've only felt one earthquake in my life," said Hughes, who grew up near Angel Stadium in Tustin, Calif. "I've probably been through 30, but a lot of times, they're in the middle of the night."
Hughes never expected to experience one in New York, but he chuckled at the extent of the media coverage surrounding the rare event.
"It's funny how big of a deal it is," Hughes said. "If this was California, it'd be, like, two seconds on the news."
