In its video series "Hidden Classics," MLB is digging into its archives and dusting off big games you might have forgotten about from your favorite stars of yesteryear. Stay tuned to MLB.com/HiddenClassics and MLB's YouTube channel for more Hidden Classic games.

History unfolds in all shapes and sizes. Look no further than the home run race of 1998.

The 62nd home run that Mark McGwire hit on Sept. 8 (pushing him past Roger Maris for the new single-season record) was a screamer down the left-field line at St. Louis’ Busch Stadium. It barely cleared the fence, almost before fans could register that it was the home run. Unofficial distance: A scosh over 340 feet.

Home runs Nos. 61 and 62 for Sammy Sosa? Precisely the opposite.

Struck at Chicago’s Wrigley Field five days after Big Mac's 62nd, these blasts – featured on this week’s edition of “Hidden Classics” – were skyscraping and grandiose. Sosa clubbed these nearly 20 years before the advent of Statcast for estimating homer distance, but each clout was measured unofficially at around 480 feet. Whether that’s accurate or not, each was hit high and far enough for Cubs fans to go ballistic before the balls finally touched down onto Waveland Avenue.

Once they did, the race was on.

Sosa’s second homer not only moved him past Maris (and temporarily even with McGwire) in the history books, but also spurred a ninth-inning comeback for the Cubs. You can see how it all played out by watching the condensed game in the video player above or at MLB's official YouTube channel.
