In the moment, even as a Twins fan, I wouldn't have rated it #1, with only 1 run 10 innings. Heck at the time I would have said Puckett's Catch of the Plexiglass and Walk-Off HR in the B11th the night before was a better game.
Even now Red Sox/Mets G6 '86 WS with Reds/Red Sox G6 '75 WS, all 3 a case can be made for at the Best. MLB Network put it right in between those 2.
In hindsight watching replays, one gets reminded of the great theater of it all with the several jams that Morris got out of unscathed. Letting a pitcher go 10 just doesn't happen anymore.
Also as time goes by, you realize that the pitcher that matched Morris' performance until he was not allowed anymore, was also a cinch Hall of Famer. John Smoltz. Additionally, the Braves went on to have a dominant decade, though just 1 World Series Trophy.
Without that game, Morris does not make it to Cooperstown. Without that weekend, Puckett likely would have had to wait much longer, perhaps waiting for a Veteran's Committee election.
