Grimm was demoted because he has options. Edwards has been great. Please consider how annoyed you are by a Cubs team on pace to win 103 games and has won 18 of their last 22. How miserable it must be to have these be the thoughts you dwell on. As long as Strop and Rondon get back and Chapman isn't hurt, I'm not annoyed, beyond standard "I should have gone to bed" emotions.
