"The Empire State Building is getting all spruced up for Opening Day.
MLB's regular season began Sunday night with a 3-0 victory by the St. Louis Cardinals over the Chicago Cubs, and Monday features a slate of 14 games. The Yankees, 27-time World Series champions, will begin their season with a home game against the Toronto Blue Jays on Monday afternoon.
The Empire State Building stands 1,454 feet tall and was the world's tallest building from its completion in 1931 until '70, when the World Trade Center was completed. The 102-story landmark is currently listed as the fourth-tallest skyscraper in America and the 25th-tallest building in the world."
