Baseball is officially back. Well, almost, but you can be sure that Opening Day is NOT the day to miss. There is something almost magical about Opening Day in the Major Leagues. The San Francisco Giants won't hold their home opener until Friday, April 8, against the St. Louis Cardinals but it is still considered their Opening Day, even though they play two away series and officially open the season Thursday, March 31, in Los Angeles against their hated rival, the Dodgers.
