I know this one is outside the range I traditionally write about, but this clip involved both a historic milestone and the St. Louis Cardinals, so I couldn't pass it up.
Willie Stargell, it is said, had atleast 100 career homeruns suppressed by spending his early career in Forbes Field. With a 20 foot high chainlink fence protecting RF and a 457 fence in left-centerfield, many believe that he would have at the very least reached the 500 Homerun plateau should he have played in a more neutral park.
Whether or not this is all true, Stargell was well regarded as one of the most prolific power hitters of the late 60's and entire 70's.
On June 29, 1977, Stargell hit his 400th career homerun off of Eric Rasmussen of the St. Louis Cardinals at Busch Stadium.
