Opening Day stats - what does a win or loss portend?

I really should do a study of wins or losses versus rankings in the standings, but why bother?

The Sox are 55-58-1 all-time on Opening Day (excluding G2 of twinbills in 1903, 1948, 1982).

Now, what I was really curious about: in the years the Red Sox have won the pennant:

1903 - it was a doubleheader. Boston won first game, lost second.
1904 - lost
1912 - won (first three games)
1915 - lost
1916 - won (first four games)
1918 - won (first six games)
1946 - won (first five games)
1967 - won
1975 - won
1986 - lost (first two games)
2004 - lost
2007 - lost
2013 - won (first two games)

As I expected, ya can't draw conclusions from a win or a loss in the first game of the season.

That said, I'd rather have a win than a loss.  It still keeps alive the possibility of going 162-0!
