Dear Joe Maddon,
Unlike last year, where everyone in your bullpen would proceed to walk a batter, this year you have a handful of reliable arms that can produce outs. When your pitcher walks four in one inning of work, it's usually time to pull him, despite whatever respect you may have for him. Please, please you've done a very nice job this year, don't risk a lead by letting Percival possibly kill himself just to maintain his reputation for being tough.
