Shock waves from an earthquake in Virginia were felt up and down the East Coast on Tuesday afternoon. Because of that, a number of Major League parks were affected. The press box swayed slightly and sent some fans toward the exits during the first game of a doubleheader between the Indians and Mariners in Cleveland. The Nationals issued a statement saying they were delaying the opening of the gates for a scheduled 7:05 p.m. ET start against the Diamondbacks while the team reviewed the situation. Workers at Yankee Stadium felt the quake as well. The 5.8-magnitude earthquake centered northwest of Richmond, Va., shook much of Washington and was felt as far north as Rhode Island and New York City.
