It's my first fanpost, so please be kind.  I found this article from Forbes on Yahoo Finance, it's a brief background on the creation of early fantasy baseball though the eyes of one of its creators Daniel Okrent.

Notable from the article regarding Harry Stein, one of the early champions of Daniel Okrent's leagues:

Today, all he'd have to do is go online. Back then, Stein was so desperate to know the outcome that he went to the locker room and asked Pete Rose, a player-manager at the time, for the results. Rose went to a nearby payphone, made a call and returned seconds later with the information. Stein later realized that Rose, now banned from baseball for gambling, had gotten the information from his bookie.

There's some Rangers related information in the article as well.  The article polls 5 experts for their fantasy picks this year.  Rangers picks include Harry Stein choosing David Murphy as his sleeper pick of 2009 and Sam Walker, the author of Fantasyland, chooses Nelson Cruz as one of his sleeper picks for 2009.
