Musk21, thanks for the article - this is easily the best compilation of such data that I've seen. It's also so recent that it doesn't even confirm Torii's numbers in full.
Brock, while it's entirely in the realm of possibility that Torii has stolen more home runs than any other Twin in history, the plexiglass only stretched to deep left center. That surely cut down the opportunities, but it's at best a third of the fence line. If Dan Gladden was the thief in question, we'd be talking about a greater impact. Anecdotally, all the Puckett leaps I recall (other than the '91 Series) came right in front of the 408 numbers.
cHawk, I'm not familiar with baseballsavant - when I tried to search, I couldn't find much beyond the statcast era.
The one option that I'm seeing is a review of Retrosheet play-by-play descriptions game by game. That's a tall task.
