I don’t know that the 7th game of the  1975 World Series was anti-climatic. I mean, the game was tied in the 9th inning. Also, the Reds trailed in that game 3-0 and they scratched and clawed their way back. It is actually one of the memorable 7th games in my memory; Joe Morgan won it on a bloop single. That, and the Jack Morris shutout in Minnesota stand out for me.
