NEW YORK -- If the bitter cold weren't enough, preparation for the Yankees' home opener also featured a rare earthquake Friday morning.

Yankees second baseman Gleyber Torres was taking batting practice from bench coach Brad Ausmus on the field when the earthquake rattled the region. The Blue Jays weren't on the field yet. The players in the visitors clubhouse didn't react to the shaking.

Yankees manager Aaron Boone, who was on the field during the quake, said he felt a vibration on his feet. He didn't realize it was an earthquake. Boone, a USC product, noted he was used to tremors after growing up in Southern California.

"I thought it was the sound system," Boone said.

The earthquake in New Jersey reached a magnitude of 4.8, according to the U.S. Geological Survey, and reportedly could be felt from Philadelphia to Boston.

In the aftermath of the earthquake, all indications were that the game would be played at 1:05 p.m. Eastern as scheduled.
