Also the 100th anniversary of Philly's first World Series title, an anniversary which will be universally ignored. When the A's left, it almost instantly became like they were never here. I'm a die-hard Phils fan, but I think it's weird that when they won in 1980, it was treated like there was never a world champion in Philly before, when the A's had won five and played in nine.

I’m still largely a novice to the play index, so when I see a search I’m not familiar with, I try to duplicate it. After a while, I got to the same point,

All of MLB: 5425 Plate Appearances in Postseason, Away Games and during 8th Inning

and when I looked at the inning batters summary I saw this:

12•PA gms 1
11•PA gms 2
10•PA gms 5
9•PA gms 9

However, those aren’t categories you can use to limit the search. I found the other games by looking at the subsequent screens 501-1000, 1001-1500, etc., but wouldn’t know how to make them into a single shared list, or if you can even do that. I’m fuzzy on the share business as well.

Anyway, here are all but the first 2 you listed – and it wasn’t easy – sometimes when I clicked for the next list, the program forgot what I was asking, and sent me back to ALL post-season plate appearances:
