nearly untouchable records...which will be the first to fall?

[mid50sbaseball]

At work anytime something really significant happens we get into a discussion about some of the records that currently stand and have for a long time and wonder if any of them will ever be broken. Which of these do you think has the best chance of some day falling? Which do you think has the best chance of standing for all time?

Note: I have only included records that were achieved post 1900 (i.e. Nolan Ryan's single season K record. A number of people have struck out more than that but all of them were in the 1880's) including any records that were achieved only partially in that time period (i.e. Cy Young's career wins 1890-1911).

I look at this list and there are so many where I just say to myself "nope...that'll never ever happen again" but you never know...
