It shouldn't surprise me, but it is crazy that he was getting 3000 racist letters a day for a while 5 years before I was born.
Imagine getting that response simply because you did something better than any human had before.
I can’t imagine the s*** he had to go through while chasing the Babes career home run record. Think of how many racist there must have been in 1974. Especially after seeing how many there still is in this past year. Add on top of that you have to hit a round ball with a cylinder object. All the while trying to hit the varying speeds, curves, sinkers and knuckleballs of the pitch. Really impressiv.
