Most of the TV ones from the last 30 years have already been mentioned. I did witness in person McGwire's 66th in 1998.
I also saw Chris Speier hit a walkoff for the Cardinals in 1986 I believe. I remember that one because my Dad would not stand up on a long fly ball when everyone else did. I asked him why and he said "I'll stand up when it's gone". Speier hit it and he stood up.
