dominance is not invincibility. there are no mario stars in baseball... outside of super mario baseball.
mariano had one of his greatest seasons ever, just last year. but even at his peak, he'll drop a game or two.
the '04 bosox series had a lot riding on it. aside from being the frickin amazing '04 bosox team, and the standard playoff pressure, the sox have the "advantage" of facing mariano up to 25 times a year now. thats quite a good opportunity to figure out what works. all that in addition to fenway fans "whose your poolboy" chants, immediately following his nephew's death. can't be pleasant.
