Perkins needs to be demoted to a 7th or 8th inning set up man until he regains his form and confidence. If he is unable to regain it, send him to the minors for a couple of weeks. Pick up the velocity on the fast ball, work on location, and get a breaking ball to break down and away. Taking out two relief pitchers who were pumped and throwing bullets and substituting a guy who started falling apart in the all star game and has never really recovered is just managing by formula instead of good situational strategy.
