I think gscottar has it right. Mo sets the starting lineup. You can smell the crap of the Modus Operandi going all the way back to the Matheny days.
Who is the only person in the organization that would replace a 3 and 4-hole hitter in the lineup with Matt Carpenter in his final season? You could bat him 9th but no, you put him in the number 3-hole. Who has the most to gain from this decision?
