It's hard to think of a more iconic time in baseball history than the 1998 home run chase, and it was on this day, 27 years ago, that St. Louis Cardinals first baseman Mark McGwire did something that no one else in MLB history had done before him.
Going head-to-head with Sammy Sosa and Ken Griffey Jr. for the 1998 home run crowd, and more importantly, the single-season home run record, McGwire stepped up to the plate against the New York Mets at the old Shea Stadium on August 20th, and proceeded to blast his 50th home run of the season.
