Contacting pros for a book

What have any of you found to be the best way(s) to contact current and former baseball players to request an interview for a book?

Thanks in advance.

 

I don't know about baseball players, but for football players, I went through both the NFL team he was both known for and his college. A lot of them were coaching or in business, as well, and not too hard to find.

 

It just depends. Twitter has actually been a good start for a ton of athletes I would book.

 

I have found some of the players on Twitter, but wasn't sure if that would be an appropriate avenue to make contact.

 

To make contact? Sure. To do an interview? No.

 

From the title, I thought this thread would be about illegal sports betting.
