Just a little rant if I may:
Baseball injuries are insanely frusterating to deal with as a fan. Clubs will give blatant misinformation concerning injuries. I am not convinced that his "back" injury this spring is unrelated to this. Teams always seem to paint a picture that is most advantageous to them, not the player.
For instance, it is difficult to tell why a player was moved to the DL. Did the team need a roster spot? Were they trying to prove a point? You just don't know much of the time.
As a fantasy baseball player, my teams have suffered many injuries. Through the years, I have been frustrated because of how bizarre some of these cases are. A couple of examples: In Jose Reye's rookie season, team doctors cleared him to play. Reyes refused. He did not play for the rest of the year. In 2003, Randy Johnson was injured. The Diamondbacks severely 'miscalculated' when he would return. His return was "a couple of weeks away" for over two months.
Just venting... I hate waiting for information when it comes to a player that is as important to my team as BJ Ryan.
