I asked because by now it the whole topic is a sabrmetric chestnut (not just the leadoff spot), and yet not even a last-place team with a lame-duck manager has said "nothing to lose, let's stack the batting order by OPS, see if there's anything to it." The notion that you give your best hitters the most PAs doesn't seem controversial, and yet so often you see a mediocre guy batting second because of his "bat control." (If the bat control is so good, why isn't he hitting .400?) Batting Cruz lead-off could have negative impact on clubhouse chemistry, I suppose, if he took the attitude "I'm a power hitter, I want men on base in front of me, no offense intended to you #8 and #9 guys." He, and other great hitters, are only human and the manager has to consider their professional pride.
