From a historical perspective, if your team loses on Opening Day, it doesn't bode well for their chances of winning the World Series. Since 1903, just 33 World Series champions had lost their first game of the season.
New York has had lots of success on Opening Day over the years. The Mets have the best record in the National League, but they haven't been quite as good as the Yankees who have the second-best record in the American League. In fact, four of the top five AL Opening Day records belong to teams in the AL East. Can you name which AL East team has the best Opening Day winning percentage in all of baseball?
